在欧陆风云4中,科技分为三种类型,分别对应着三类君主点数。每种类型的科技都细分为33个等级,随着等级的提升,可以激活新的能力、建筑单位 ,或是改进已有的技能。在游戏中,科技的每个等级都与特定的年份(该项科技在历史中的出现时间)相关联。(参见:科技列表中的年份列目)

科技类型

行政科技

Administrative tech.png 行政科技组主要是用来解锁新的政体形式,增加生产效率,解锁国家理念,解锁提升建筑等级。这些大部分与稳定度和收入有关。提升行政科技等级,可以提高行政效率,降低造核费用,较少过扩惩罚,但也伴随着殖民地更高的独立意愿。

外交科技

Diplomatic tech.png 外交科技主要与其他国家和飞地的互动有关。提高外交科技等级可以提高贸易效率,殖民距离,外交影响和海军力量。外交科技解锁的建筑都是贸易和海洋相关的。

军事科技

Military tech.png 军事科技的主要效果为增强陆军素质,并为国家解锁新的兵种类型,提高部队的士气、机动和军事战术(tactics),还可以解锁与战斗相关的建筑,例如征兵中心和要塞等。

科技组

科技组决定了国家在开局时的科技等级和大致的地图探索范围。每个国家都拥有某一个科技组。[1]每个科技组都有一组独特的陆军单位类型,代表了该科技组的国家的大致军事策略。

几乎所有国家在开局时都会以其科技组来决定是否已接受封建主义思潮(下表列出了一些例外)。没有接受封建主义的国家将会承受思潮机制带来的50%科技研究惩罚。所有国家在开局时都会根据其科技组获得对应的初始科技等级,不论其是否拥有思潮惩罚。

Nomadic.png 游牧 +0% 满洲国家:(建州, 海西, 野人)

原始土著

"原始土著" 是指拥有以下科技组的国家:

  • 北美洲科技组 北美科技组
  • Mesoamerican technology group 中美洲科技组
  • 安地科技组 安第斯科技组
  • South American technology group 南美洲科技组

Primitive nations get reduced income from Gold gold and cannot build boats, preventing them from colonizing non-adjacent provinces. They can be annexed at no diplomatic point cost and with minimal Aggressive expansion impact.png aggressive expansion impact by nations using the Colonial conquest casus belli from the Exploration idea group.png exploration idea group (also possible by other primitives). Colonial nations may attack primitives without involving the mother country. They also do not cause separatism in conquered provinces if the conqueror is not primitive.

Nations with a primitive technology group can shrug off the label of "primitive" (giving them full gold income and ships, etc.) by reforming their government (for nations in the 北美洲科技组 North and South American technology group South American technology groups) or religion (for natives in the Mesoamerican technology group Mesoamerican and 安地科技组 Andean technology groups).

科技花费

The cost for researching a new technology level consists of the base cost, 600 monarch points,[2] multiplied by the current institution penalty and all modifiers, plus 100%.

思潮惩罚

主条目:思潮

在欧陆风云4所处的历史年代中,曾经有七种思想广为传播并改变了这个世界。而在游戏中,那些未能接受这些思潮的国家想要在科技研发中跟上其它国家——特别是思潮诞生的欧洲——的脚步将会变得愈加困难。每一个已经出现但是尚未被接受的思潮将会带来+1%/年的科研花费惩罚(上限为+50%),这有可能使得研发科技的花费超过君主点数的储存上限。这些惩罚将随着新思潮的不断出现而累加,例如,一个尚未接受封建主义思潮的国家在1821年将会受到+350%(即7*+50%)的科研花费惩罚。

通用修正

通用修正影响所有类型科技的花费。

年代惩罚

科技花费随着时间而增加。[3]这一效果是线性增加的,并且只与当前科技等级的历史年份挂钩。也就是说,如果当前科技等级的历史年份是1444年,年代惩罚就是0%;如果当前科技等级的历史年份是1821年(游戏结束的时间),年代惩罚就是30%[4]

邻国加成

若你某个类型的科技等级低于你科技等级最高的邻国(须与该国首都有陆路相通)或同科技组的国家,则每低1级,你可以获得-5%的科技花费加成[5],最高可以达到-75%[6]。简单来说,科技落后的国家可以通过接壤一个科技先进的不同科技组国家来获得科技增益,而同科技组的国家即使不用接壤也有此效果。

间谍奖励

当你拥有“窃取科技”(外交科技9级)的能力时,若你在某个科技较先进的国家有间谍网络,你研究该国拥有的科技时会享受一定的减成。

超前惩罚与加成

若国家达到某项科技等级的时间早于该科技等级的历史年份,则称为该国科技超前

国家科技每超前1年,研究下一等级的花费便增加10%[8]。如果某个国家的科技超前了10年,那么再研究下一级科技就不可能了,因为科技花费已经超出了君主点数的存储上限。

若一国某项科技超前,该国将依超前科技的项目不同而获得不同的加成:

  • 行政科技超前会带来 Production efficiency.png +20%生产效率加成和Corruption.png-0.05腐败[9]
  • 外交科技超前会带来 Trade efficiency.png +20%贸易效率加成和 Corruption.png -0.05腐败[10]
  • 军事科技超前不会带来任何加成[11]

科技列表

Administrative tech.png 行政科技

等級 科技 效果 年份 描述
0 Tribal Government 1350 The most basic unit of governance is an extended family where all members of a community claim kinship with each other, a tribe in other words.
1 Advanced Tribes 1390 A family structure with most senior members at the top can work for nonrelated groups. In its simplest form, the system is meritocratic, with leadership tasks assigned to the most capable.
2 Feudal Monarchy 1420 As social organization improves, so do things like food production. Increasing food production allows a society to upkeep people who aren't producers of food themselves. This leads to creation of a military elite, to defend against enemy's military elite. Supporting of the military elite is the basis of the feudal system.
3 Medieval Administration 1440 With a military elite to govern our society, the next stage of development is to have a literate class of administrators. Usually these will be drawn from the ranks of clergy.
4 Temples
  • Latin temple.png 允許建造 temples
1453 Housing the machinery of government is as important as the machinery itself and one should never forget of the importance of religion when doing so.
5 National Ideas 1466 Choosing the direction a country is going to take is perhaps the toughest choice a ruler will ever face. National ideas are the concepts that will shape our country for years to come.
6 Workshop
  • Latin workshop.png 允許建造 workshops
1479 Prior to the Industrial Revolution the Workshop- or Putting-out System was used in Early Modern Europe to organize the production of everything from Textiles to Wrought Iron. With materials provided craftsmen could refine various goods either in workshops or in their own home, bypassing the rigid restrictions of the guilds.
7 Renaissance Thought 1492 The notion of a noble oligarchy ruling the society has existed, since well, at least the Roman times, and remained popular in some parts of the world. Now this idea is once more gaining popularity amongst those who matter.
8 Courthouse
  • Latin courthouse.png 允許建造 courthouses
  • Number of states.png +3 直轄州數量
1505 The problem with a hereditary local nobility is that they tend to value their local interests over those of the rest of the nation. We need to steadily expand the reach of the government, which begins with two of the most important areas of administration, justice and taxation.
9 The Scythe
  • Production efficiency.png +5% 生產效率
1518 Although it has been in existence for a long time, the scythe somehow still isn't the most popular tool for harvesting crops. By encouraging peasants to use a scythe instead of a sickle we will improve the efficiency of our harvests.
10 Modern Theocracy 1531 The development of the social structure is not exclusive to the aristocracy. The clergy too have to improve their internal governance. This will assist in the development of modern thought in our country.
11 Textile Manufactory
  • Textile manufactory.png 允許建造 textile manufactories
1544 Textiles were manufactured since time immemorial. The invention of stocking frame in 1589 was the first step towards the industrial revolution and the beginning of mechanization. This invention would lead to increase in textile production.
12 Early Modern Administration 1557 In time it became apparent that a more centralized bureaucracy with administrative bodies run by educated officials employed directly by the state was a necessity for the ambitious projects of the Early Modern rulers.
13 Improved Drainage
  • Production efficiency.png +5% 生產效率
1570 The more land we can cultivate, the bigger the population we can feed in that area. Gradual improvements in drainage have led to wetlands being brought into use.
14 Scientific Experimentation
  • Idea unlock 解鎖第四個理念
  • Plantation.png 允許建造 plantations
1583 While it is true that we stand on the shoulders of our ancestors it is high time that we start to learn about the world from our own, well documented observations. By observing the world around us and by experimenting to prove or disprove our ideas about it we can reach further than those before us.
15 Military Administration 1596 The ever increasing armies of the 16th century put bigger and harder demands on the administrative systems of states. By creating a permanent organization charged with taking care of the procuring and planning of Military supplies and by keeping more troops on the rolls even during wintertime or peacetime we will in the long run be able to field large armies more cheaply and be able to support these armies more efficiently while at war.
16 Metallurgy
  • Production efficiency.png +5% 生產效率
1609 The process to produce wrought iron was under continuous improvement and by the early 17th century the finery process came to overtake the older Osmond process. Iron production could now be specialized with the working of the iron no longer taking place at the same location as it was mined and more, stronger and purer iron would in time lead to developments in many other sectors.
17 University
  • Latin university.png 允許建造 universities
  • Administrative efficiency.png +10% 行政效率
  • Development.png +10% Development efficiency
  • Number of states.png +5 直轄州數量
1622 The great medieval universities were of course great but they were not able to produce enough graduates to staff our growing administration. We need to expand our universities or we will fall behind.
18 National Sovereignty 1635 The many and long wars of the first half of the 17th century have led to an international diplomatic system where the territorial integrity of states is a cornerstone. States rather than individual rulers or supra-national groupings are the actors on the international arena and no state has the right to intervene in the internal affairs of another.
19 Cathedral
  • Latin cathedral.png 允許建造 cathedrals
1648 Promotion of religion will be crucial for the stability of the realm. It is not enough to be great, people must be able to see our greatness. The ancients knew how to display their greatness and we will do the same by building monuments to withstand the test of time.
20 Absolute Rulership 1661 There are many people who demand to be given a role in the government, but in reality mostly want rewards without effort. A new interesting idea of absolutism is spreading, which is a system where we dispose of those parasites and govern alone.
21 Land Clearance
  • Production efficiency.png +5% 生產效率
1674 Large-scale woodlands are of course useful as a source of firewood and a place for hunting, but if the trees were to go, those lands could be used for farming instead.
22 The Constitution 1687 A new philosophical concept called constitutionalism has been developed, where the government accepts legal limits to its power. This is an intriguing idea, but I can't see it catching on.
23 Measuring the World
  • Administrative efficiency.png +10% 行政效率
  • Development.png +10% Development efficiency
1700 The new sciences have given us a number of different ways to describe and measure the world around us. Let us send these learned men out into the world in general and into our country in particular. We cannot know what resources are at our disposal until we have thoroughly searched all our lands for minerals, counted every last subject and assessed every last enterprise.
24 Bonds and Tontines
  • Latin counting house.png 允許建造 counting houses
  • Number of states.png +15 直轄州數量
1715 Paying for the upkeep of the army, the navy and the administration itself accounts for the majority of the expenses for any state. As these are expenses that can run away quickly however taxes and tolls can be frustrating and inflexible ways to raise the money needed. While national debt is far from unheard of we need to come up with better plans for raising money. Bonds, tontines and other similar plans can be used both domestically and abroad to finance unforeseen expenses and will allow us to make much better use of the money we do have to develop our country.
25 Improved Production
  • Production efficiency.png +5% 生產效率
1730 Having the technical means to improve land and thus production is useless without incentives to do so. By reforming the laws of land tenure we can provide greater incentives to adopt improved methods of production.
26 Separation of Powers 1745 Our thinkers continue to develop the flawed notions of constitutional limitations on government power. Amusing as these ideas may seem, they also inspire progressive thought in other areas.
27 Modern Bureaucracy
  • Administrative efficiency.png +10% 行政效率
  • Development.png +10% Development efficiency
  • Number of states.png +5 直轄州數量
1760 An anonymous treatise on political theory has emerged, and despite efforts to suppress it it is quickly spreading across the world. It deals with the nature of forms of government, be they monarchies, despotisms, or democracies, and argues for a strict separation of the executive, legislative, and judiciary branches. This would protect the people and limit the power of a monarch, which is understandably a very popular prospect for many of our subjects. Despite the unfortunate implications for the power of monarchs, these ideas may well benefit our nation greatly.
28 Rotherham Plough
  • Production efficiency.png +5% 生產效率
1775 The basic plow in use in Europe has been unchanged since the Roman times. Now, thanks to improvements in design, the same plough can be made much lighter, reducing workload on draft animals, allowing them to do more work.
29 Rights of Man 1790 These so-called enlightened philosophers are nothing more than madmen, with notions such as the separation of church and state and sexual or racial equality. Still, their thinking has led to the development of new ideas in the areas of state and government.
30 Advanced Production
  • Production efficiency.png +5% 生產效率
1805 At the forefront of current revolutionary thought is the radical notion of equality for all. Philosophers from different parts of the world have worked together to create a document entitled the 'Declaration of the Rights of Man and of the Citizen', proclaiming that these rights are universal and should be enforced by law. It is likely that this will have ample repercussions for the development and spread of the concepts of freedom and democracy, and we would do well not to lag behind.
31 Revolutionary Ideals 1820 These foolish revolutionaries think they can simply consign hundreds of years of progress to the dustbin of history, all in the name of such outlandish concepts as liberty and equality. We will defeat them through the tried and tested plan of stealing the bits and pieces of their ideas that we like.
32 Four Field Rotation
  • Production efficiency.png +5% 生產效率
1835 My secretary of state assures me that the switch to clover as a fodder crop and the addition of the turnip in a ‘four field' rotation will increase yields in agriculture. I am inclined to promote this idea.

0 Early Ships 1350 Shipbuilding can mean a lot of different things, it is amazing how far you can get on a raft for example. However, this is not the same as creating a fleet to enforce policies of a state. This requires a whole different approach to the building of ships, as well as developing ways to control the navy you've built.
1 Merchants & Trade
  • Merchants.png Can place Merchants
  • Trade range.png +100 貿易範圍
  • Global settler increase.png +10 全局移民數量
1390 The patterns of trade had been seriously disrupted in the 14th century, possibly due to plagues and pandemics. Now trade is slowly beginning to recover.
2 The Barque
  • Trade range.png +100 貿易範圍
1420 The barque has a long history, beginning as an Ancient Egyptian river boat. However, since then the term has gradually come to mean a light ship.
3 The Early Carrack
  • Morale of navies.png +0.1 海軍士氣
  • Naval maintenance modifier.png +10% Naval maintenance
  • Colonial range.png +100 殖民範圍
  • Trade efficiency.png +5% 貿易效率

1440 The first true ocean-going ship. Unlike galleys and cogs, Carracks can serve the role of proper ocean-going warships.
4 Marketplace
  • Trade range.png +10 貿易範圍
  • Latin marketplace.png 允許建造 marketplaces
1453 Creation of legal and regional infrastructure in order to promote trade will not only encourage commerce but also allow us to better tax it.
5 Basic Financial Instruments
  • Trade range.png +20 貿易範圍
  • Naval maintenance modifier.png +10% Naval maintenance
  • Trade efficiency.png +5% Trade Efficiency
1466 Overseas trade is very risky but also highly profitable. The development of financial instruments like letters of credit will help reduce the risk, increasing our profits.
6 Docks
  • Latin dock.png 允許建造 docks
  • May steal maps May steal maps
1479 Land transportation of a lot of cargo is simply too expensive, moving it by ship is more efficient. Building shipyards will provide enough ships to do so.| style="text-align: justify;" | As time progressed an expanding and increasingly advanced shipbuilding sector put new demands on seaports. Well maintained and planned docks went from being a convenience to a necessity for any location wishing to become a centre for naval or maritime activity.
7 Naval Ambitions
  • Morale of navies.png +0.3 海軍士氣
  • Colonial range.png +115 殖民範圍
1492 With an extra boost to naval morale, our sailors will conquer the waves and rule the seas. While our colonists will be able to brave the dark corners of the world, founding new settlements farther from home than ever before.
8 Shipyards
  • Trade range.png +10 貿易範圍
  • Morale of navies.png +0.2 海軍士氣
  • Latin shipyard.png 允許建造 shipyards

9 Carracks & Caravel
  • Colonial range.png +50 殖民範圍
  • Naval maintenance modifier.png +10% Naval maintenance
  • May study technology May study technology
1518 Development of the lateen sail allowed Carracks to sail much closer to the wind than earlier vessels. Enhanced maneuverability made them superior to other ships.
10 The Flute
  • Trade range.png +20 貿易範圍
  • Trade efficiency.png +5% 貿易效率
  • Global settler increase.png +10 全局移民數量
1531 A Flute is a specialized cargo vessel capable of carrying a large load with a very small crew. Flutes were designed to be built cheaply and in large numbers. A useful ship if you need to move things across the oceans.
11 Wharf
  • Colonial range.png +100 殖民範圍
  • Naval equipment.png 允許建造 naval equipment manufactories
1544 The great wharfs and jetties will act as entrepôts for the world's goods. Let us build them and prosperity will follow.
12 Man of War
  • Morale of navies.png +0.4 海軍士氣
  • May slander merchants May slander merchants
1557 Throughout the 16th century the increasing sailing ability of ships together with a growing number of more efficient guns have led to an increasing specialization of ship types. A Man of War is a ship dedicated entirely to sea warfare with a greater number of guns and ammunition than a ship that would also have to act as a Merchantman could ever hold. In the long run this development will lead to growing permanent navies and the development of naval tactics to better fit the new realities of sea warfare.
13 Chartered Companies
  • Trade efficiency.png +5% 貿易效率
1570 The world is a big place and in order to develop our trade in it sometimes quite big risks must be taken. Luckily there are Merchants in our country that would be willing to do so, using mostly their own capital. By sanctioning such companies with a Government charter giving them special rights to exercise government powers as well as monopolies in certain areas we can control and encourage commercial development of everything from foreign trade contacts to our colonial possessions overseas.
14 The Galleass
  • Trade Company 允許建造 trade companies
  • Max promoted cultures.png +1 Max promoted cultures
1583 Galleys were light and small, and it was very difficult to mount cannons on them. The Galleass was a larger vessel capable of carrying a broadside of cannons like a man-of-war. To compensate for this extra weight, Galleass would be equipped with an additional sail.
15 The Galleon
  • Colonial range.png +50 殖民範圍
  • Naval maintenance modifier.png +10% Naval maintenance
  • Global settler increase.png +15 全局移民數量
  • May sabotage recruitment May sabotage recruitment
1596 The Galleon was created by lowering the forecastle and elongating the hull. These changes in design improved the speed and stability of the ship. Which was of vital importance for Galleons to serve as better gun platforms.
16 Development of Maritime Law
  • Trade range.png +20 貿易範圍
  • Trade efficiency.png +5% 貿易效率
1609 With more and more countries sending their subjects or citizens abroad on various trading ventures and with so many living so close to each other for so long times it has become absolutely essential to have at least a basic concept of common laws of the seas. With publications such as 'Mare Liberum' or the later 'De Dominio Maris Dissertatio' the foundations to an international law of the seas has been laid.
17 Merchantman
  • Colonial range.png +50 殖民範圍
  • Trade range.png +20 貿易範圍
  • Latin trade depot.png 允許建造 trade depots
1622 Further development of transport ships led to construction of larger and faster vessels, which still tried to maintain the simplicity of construction of the Flute. These ships fell under the generic term Merchantman.
18 Line of Battle
  • Morale of navies.png +0.5 海軍士氣
  • May sow discontent May sow discontent
1635 In order to make better use of the various developments in naval warfare new tactics are required. The evolution of broadside cannon have meant that the most efficient way for ships is no longer to seek to board the other party but rather to form a line of battle to be able to maximize the amount of firepower directed at the enemy.
19 The War Galleon
  • Colonial range.png +50 殖民範圍
  • Naval maintenance modifier.png +10% Naval maintenance
  • Latin dock.png 允許建造 drydocks
1648 The War Galleon, also known as a race-built Galleon, was built by reducing the number of decks on a Galleon. This sacrificed cannons for maneuverability, which proved to be beneficial in combat.
20 Naval Professionalization
  • Trade range.png +20 貿易範圍
  • Trade efficiency.png +5% 貿易效率
  • Max promoted cultures.png +1 Max promoted cultures
1661 Even at the beginning of the 17th century permanent navies were quite small and even naval powers of note would mostly maintain a naval force to meet their immediate needs. Over time however we are moving in the direction of a larger professional navy. Unless we want to see our rivals overtaking us in naval matters we must strive to create a larger permanent navy with an administrative structure to support it as well as ensure that a naval career can be a permanent occupation for our officers.

1687 In 1614 a rather mad physician wrote a treatise suggesting that scurvy was a result of a dietary problem and could be solved by consuming lemon or lime juice. As it turns out, there was method in his madness and we have started providing this new diet for our sailors. Other countries call us limey now.
23 Heavy Frigates

1715 A special version of the Frigate originally developed for operation in the Baltic. It kept a broadside of a frigate, but had a shallow draft and oars giving greater maneuverability in shallow waters, while sacrificing seakeeping in open oceans.
25 The Threedeckers
  • Morale of navies.png +0.5 海軍士氣
  • Naval maintenance modifier.png +10% Naval maintenance
1730 The addition of a third deck was a small sacrifice in maneuverability for a huge gain in close combat. The additional deck gave the ship an ability to fire onto the decks of smaller two-decker ships, while at the same time protecting its own deck.

1745 The East Indiaman was the largest merchant ship built, it typically could displace in excess of 1,000 tons and measure over 175 feet in length. Those queens of the oceans were the most efficient way of moving men and cargo around the globe.
27 Public Punishments

  • May agitate for liberty May agitate for liberty
1760 Life at sea is full of dangers and thus the punishments need to be harsh. If they do not have a sufficient deterrence effect, we will quickly run into trouble. Over time a system of highly public punishments has evolved, and now the time has come to formalize those. This will greatly enhance discipline at sea.
28 Joint Stock Companies

1775 As trade grew, so did the risk. New ways of accumulating capital and managing risk needed to be developed. In Joint Stock Companies the risk of enterprise was shared among their many shareholders.
29 Midshipmen Cadets

  • Naval maintenance modifier.png +10% Naval maintenance
1790 Originally the midshipman was a rank given to an experienced seaman who worked amidships. Men who aspired to become officers would often choose to serve in this role. If we formalize this, and make it a precondition for acquiring the rank of a commissioned officer, we will ensure our future leaders understand the ships they command.

1820 Building ships that are slightly faster than those of our opponents, even if the amount of this extra speed is so negligible that it is of no military significance, can still fill our crews with confidence and make our enemy wary of taking us on in an even fight.

1835 The ongoing trade deficit between Europe and China has caused a shortage of silver bullions in Europe and all over the world. Switching from silver coinage to gold coinage will allow new coinage to enter circulation and get trade flowing in ever greater amounts.

1350 The citizen soldier, the tribal warrior, essentially the non-professional. The starting point for any military.
1 Medieval Military
  • Latin fort01.png 允許建造 castles
  • Infantry shock +0.10 Infantry shock
  • Infantry fire +0.10 Infantry fire
1390 The creation of a professional military class is the first step to creation of a modern army.
2 Eastern Swarm
  • Infantry shock +0.20 Infantry shock
  • Cavalry shock +0.20 Cavalry shock
  • Combat width.png +5 Combat width
1420 Charging blindly at the enemy is perhaps not the greatest tactic known to man, but it is one of the simplest to master. It is also the stepping stone to more advanced strategies.
3 Late Medieval Military
  • Morale of armies.png +0.50 陸軍士氣
1440 By the end of the middle ages the land armies had become more professional and well organized. Better systems are in place to support the mix of levies and professional soldiers that now dominate the battle fields and the power of infantry is slowly but steadily gaining on the cavalry arm.
4 Pike Square
  • Morale of armies.png +0.50 陸軍士氣
  • Military tactics.png +0.25 Military tactics
1453 Throughout the Middle Ages cavalry's dominance was being challenged by disciplined pikemen. In battles such as Bannockburn or the Golden Spurs, cavalry was defeated by pikes. A combination of improved training and discipline, and the addition of swordsmen to provide close combat support has raised this formation to the peak of its efficiency.
5 Standardized Pikes
  • Supply limit.png +50% Supply limit
  • Infantry shock +0.15 Infantry shock
  • Cavalry shock +0.20 Cavalry shock
  • Combat width.png +2 Combat width
1466 A pike is a remarkably simple weapon to make, but to get the full benefit from the use of pikes, it's required for the whole formation to be wielding weapons of similar length and blade.
6 Arquebus
  • Latin barracks.png 允許建造 barracks
  • Infantry shock +0.30 Infantry shock
  • Infantry fire +0.20 Infantry fire
  • Military tactics.png +0.25 Military tactics
  • Combat width.png +2 Combat width
1479 Although hand cannons had been developed in China in the 12th century and had spread to Europe by the 14th, the weakness of these weapons reduced their battlefield utility. Light and reliable Arquebus was able to displace bow due to three main factors. It had better armor penetration, it was easier to train men to use it, and it did not rely on the strength of the user.
7 The Limber
  • Artillery fire +1.00 Artillery fire
  • Artillery shock +0.05 Artillery shock
  • Military tactics.png +0.25 Military tactics
Artillery.png Artillery
  • Large Cast Bronze Mortar
  • Houfnice
1492 Artillery had been documented in Europe since the thirteenth century, but due to its lack of mobility, it had very limited battlefield use. The development of the Limber in the 1470s allowed guns to become more mobile and thus useful.
8 Pike and Shot
  • Latin regimental camp.png 允許建造 regimental camps
  • Infantry fire +0.25 Infantry fire
  • Cavalry shock +0.80 Cavalry shock
1505 The Arquebus was easy to use as a weapon, but was also inaccurate and slow to fire, leaving its user vulnerable to cavalry charges. Blending with Pikemen allowed Arquebusiers to fire and then fall back to be shielded by Pikemen when enemy cavalry or infantry appeared.
9 Professional Officers
  • Military tactics.png +25% Military tactics
  • Combat width.png +1 Combat width
1518 The value of training and experience has always been great on the battlefield. With the advent of gunpowder and the tactical changes associated with it and other infantry weapons came a great demand for units versed in these new innovations. As professional armies were still far away this need had to be filled by mercenary units such as the Condottieri, Swiss Mercenaries or Landsknechts. A growing class of professional mercenary officers came to live of supplying these regiments to needing states in the middle of the military transition.
10 Reiter

1531 Pike and shot formations proved a major threat to medieval knights. The initial response was heavier armor to counter the power of gunpowder weapons, but this slowed down cavalry, reducing their shock power. Reiters were usually armed with two pistols and a sword, allowing them to either shoot or charge depending on the opposition they faced.
11 Matchlock Musket
  • Weapons manufactory.png 允許建造 weapons manufactories
  • Infantry shock +0.20 Infantry shock
  • Cavalry fire +0.50 Cavalry fire
  • Combat width.png +2 Combat width
1544 The Arquebus proved to be a very effective weapon for armor penetration, the result was that armor began to get heavier to resist its fire. A larger musket could deliver a heavier round offering better armor penetration
12 Spanish Square
  • Supply limit.png +50% Supply limit
  • Military tactics.png +0.25 Military tactics
1557 Spanish Square developed naturally from the Pike and shot formations. At its core was a traditional Pike Square. At each of the corners it had a group of Arquebusiers. It kept the staying power of the traditional pike square and enhanced it with the firepower of the Arquebus.
13 Trunnions
  • Artillery shock +0.10 Artillery shock
  • Artillery fire +0.40 Artillery fire
Artillery.png Artillery
  • Large Cast Iron Cannon
  • Small Cast Iron Cannon
1570 The new and more mobile artillery had one problem - it could not be easily elevated up and down to adjust its firing range. Trunnions were cylindrical protrusions that acted as mounts for the gun on its carriage, which allowed it to be tilted and thus aimed better.
14 Tenaille
  • Latin fort02.png 允許建造 bastions
  • Infantry fire +0.30 Infantry fire
  • Combat width.png +2 Combat width
1583 It was difficult to fire around curved walls, thus once attackers got close enough to the fortification, the ability of other parts of the defenses to provide flanking fire was nullified. The development of star-shaped bastions allowed every part of the wall to be supported from other parts.
15 Maurician Infantry
  • Morale of armies.png +1.00 陸軍士氣
  • Military tactics.png +0.25 Military tactics
1596 The size and depth of the Spanish Square gave it staying power but made it slow and cumbersome to maneuver on the battlefield. It also led to a large percentage of troops being inactive during battles. Maurice of Nassau, the Stadtholder of the Netherlands, reduced the total number of men in the formation to make it more mobile and reduced its depth, so it maintained the same firepower and shock values.
16 Standardization of Calibre
  • Latin training fields.png 允許建造 training fields
  • Artillery shock +0.10 Artillery shock
  • Artillery fire +1.00 Artillery fire
  • Combat width.png +1 Combat width
Artillery.png Artillery
  • Chambered Demi Cannon
1609 With artillery's growing importance in the battlefield, also the number of firearms kept increasing. But because each gun was made separately, it also required great effort to resupply. In 1544, Emperor Charles V declared that there would be only 5 calibres of gun, while King Henry II of France set 6 standard calibres.
17 Flintlock Musket
  • Icon shock.png +1.00 Cavalry shock
  • Supply limit.png +50% Supply limit
1622 The matchlock firing mechanism's biggest weakness was the need to keep the match lit in order to fire the weapon. Although wheellock was developed, it was too expensive to produce to enter into mass use. The development of flintlock created a more reliable weapon.
18 Carbine
  • Icon maneuver.png +25% Improved flanking range
  • Combat width.png +2 Combat width
Artillery.png Artillery
  • Leather Cannon
1635 The carbine was a shorter form of the musket.
19 Gustavian Infantry
  • Latin fort03.png 允許建造 star forts
  • Military tactics.png +0.25 Military tactics
  • Supply limit.png +50% Supply limit
1648 Gustavus Adolphus, King of Sweden, further developed infantry units to improve their firepower. His infantry formations were narrowed and made rectangular to increase the number of muskets that could fire in each volley. Attachment of small artillery pieces further increased the firepower of infantry.
20 Killing Grounds
  • Infantry fire +0.50 Infantry fire
  • Combat width.png +2 Combat width
Artillery.png Artillery
  • Swivel Cannon
1661 With development of new bastions engineers began to improve the art of positioning them to channel attacking armies into specially prepared killing grounds, where the defenders could inflict maximum amount of casualties on their enemy.
21 Line Infantry
  • Military tactics.png +0.25 Military tactics
  • Infantry shock +0.50 Infantry shock
1674 Thanks to bayonets, each musketeer could function as a pikeman as well. This allowed pikes to be removed from infantry equipment and provided infantry formations with more firepower.
22 Cartridge
  • Latin conscription center.png 允許建造 conscription centers
  • Cavalry fire +0.50 Cavalry fire
  • Artillery shock +0.10 Artillery shock
  • Artillery fire +2.00 Artillery fire
  • Combat width.png +2 Combat width
Artillery.png Artillery
  • Coehorn Mortar
1687 In the 1620s the idea of combining the shot and powder into a single unit, a cartridge, allowed for faster reloading and thus firing. This in turn dramatically improved the firepower of guns.
23 Light Cavalry
  • Cavalry shock +1.00 Cavalry shock
  • Military tactics.png +0.25 Military tactics
  • Icon maneuver.png +50% Improved flanking range
1700 Heavily armored cavalrymen were by their nature cumbersome to form up and vulnerable on the battlefield. Lighter cavalry was added to armies to act as scouts for the army during marching and screen heavier cavalry before its charge on the battlefield.
24 Covered Way
  • Latin fort04.png 允許建造 fortresses
  • Military tactics.png +0.25 Military tactics
  • Combat width.png +2 Combat width
1715 An outer ditch became a key area for the siege. If attacking troops gained control of the glacis, then the bastions would be lost. The ditch became the first line of defense for a fort. Access to this ditch, and ensuring it kept providing protection to defending troops became a key part of fortification design.
25 Royal Mortar
  • Artillery shock +0.10 Artillery shock
  • Artillery fire +2.00 Artillery fire
Artillery.png Artillery
  • Royal Mortar
1730 Improvements in metallurgy allowed cannons to become lighter and more reliable. This allowed them to become more effective on the battlefield.
26 Light Infantry Companies
  • Morale of armies.png +1.00 陸軍士氣
  • Combat width.png +2 Combat width
1745 First introduced to the Austrian army as irregular troops from the military frontier during the Seven Years' War, Light Infantry Companies were deployed in loose order and proved to be very effective at harassing enemy and leading assaults on entrenchments.
27 Bayonet
  • Supply limit.png +50% Supply limit
  • Infantry fire +0.50 Infantry fire
1760 Although a musket could always be wielded as a club, it was not an effective hand-to-hand weapon. A bayonet was a blade that was fitted to the end of a musket, allowing the weapon to function as a spear. Initial bayonet designs plugged the barrel, making it an either or choice, but the development of the ring bayonet, which fitted around the barrel, turned a musket into a useful support weapon.
28 Cuirassier
  • Infantry shock +0.50 Infantry shock
  • Icon maneuver.png +25% Improved flanking range
1775 Although a cuirass (or a breast plate) had existed for many years, only recently a new style of cavalryman gained popularity, with only a breast and back plate, which provided better balance between protection to the key parts of the body and mobility.
29 Defense in Depth
Artillery.png Artillery
  • Flying Battery
1790 Thanks to the building of several layers of fortification, overrunning of outer bastions simply moved the siege to the next layer, forcing attackers to prepare new locations to site guns and increasing the length of the siege.
30 Impulse Warfare
  • Military tactics.png +0.25 Military tactics
  • Morale of armies.png +1.00 陸軍士氣
  • Icon maneuver.png +25% Improved flanking range
1805 The introduction of light infantry troops led to a change in warfare. Skirmishers were deployed forward in loose order to distract and harass the enemy before the main infantry attack, which was typically delivered in either a line or a column.
31 Rifle
  • Cavalry shock +1.00 Cavalry shock
  • Infantry fire +1.00 Infantry fire
  • Supply limit.png +50% Supply limit
1820 The musket's weakness was the fact that it was highly inaccurate beyond 50 yards. The rifle, although never a standard infantry weapon, added greater range to elite units, which gave the army a greater overall punch.
32 Field Howitzer
  • Military tactics.png +0.25 Military tactics
  • Artillery shock +0.10 Artillery shock
  • Artillery fire +2.00 Artillery fire
1835 Originally developed for siege purposes, the howitzer fired a high angled projectile over the fortifications and into the town inside. The field howitzer, a lighter more mobile variant, would fire an explosive shell above enemy troops. Mixed with other artillery types, it added to the effectiveness of artillery brigades.
