CALL OF WAR CLASSIC

Call of War Classic

The current version of the game is different to the old version that existed years ago, in terms of features, restrictions and balancing. That older version is also referred to as 'Call of War' Classic or CoW1.0. From time to time Events are hosted that run on the old Classic version, so players participating in them should know about the differences. Similarly, players who come back to the game after a long hiatus should learn about the recent changes and new additions to the game.

Below is an overview table that explains which parts of the game changed from the old version (CoW Classic) to the new 'Call of War' version.

Unit Production

	Call of War Classic	New Call of War
Production buildings	Nearly all units require an Industrial Complex to be produced.	New production buildings were added to the game. Different tech branches need different buildings for production. E.g. Tanks require a Tank Plant. Artillery requires an Ordnance Foundry.
Urban focus	Production buildings and units can be built anywhere.	Production buildings and units can only be built in urban provinces (cities).
Production categories	Units are separated in production categories based on their armor class.	Units are separated in production categories based on their production building. This makes building requirements easier to understand.
Production requirements	Upgrading buildings is required to unlock production of higher unit levels.	All units can be produced with the first production building level. Unit production time increases a lot for higher unit levels, so upgrading the production buildings is highly recommended to reduce production times.
Production time	Upgrading the production buildings reduces unit production times unconditionally.	Upgrading the production buildings reduces unit production times until the minimum production time of a unit is reached, at which point it is not reduced further. Each unit has a different minimum production time.

Buildings

	Call of War Classic	New Call of War
New Buildings	A smaller set of buildings.	New buildings have been added and building roles have been revised. A list of all buildings: Barracks, Tank Plant, Naval Base, Ordnance Foundry, Aircraft Factory, Secret Lab, Industry, Bunkers, Capitol, Infrastructure, Recruiting Station, Propaganda Office, Local Industry, Airstrip, Fortifications, Local Port.
Building effects	Most buildings have multiple effects and benefits.	Most buildings only have one or two effects and benefits. Effects and benefits are assigned to specific buildings, and new building types were added to grant specific benefits to provinces.
Province separation	All buildings are available in urban and rural provinces.	Certain buildings are only available in urban provinces (e.g. production buildings), while certain buildings are only available in rural provinces.
Hidden buildings	All buildings are visible in fog of war.	Buildings in fog of war are not visible to other players. They have to be uncovered first by scouting or espionage.

Resources

	Call of War Classic	New Call of War
Resource distribution	Amount of resources produced is distributed evenly regardless of the province type, while the type of resources somewhat depends on the province type (urban vs. rural).	~75% of the resource production amount is located in urban provinces and ~25% is located in rural provinces. Urban provinces produce all 5 main resources. Rural provinces produce relatively more manpower. Countries still have different resource type distributions in their rural provinces.
Production resources	Units require for the most part the same resource types to be produced, across most tech branches, resulting in higher demand for specific resources.	Different tech branches require different resource types, with resources spread more evenly across all units. Resource demand is more evened out.
Building resources	Buildings require for the most part the same resource types to be constructed, resulting in higher demand for specific resources.	Buildings require different resources with resources spread more evenly across all buildings. Resource demand is more evened out.
Research resources	Research requires the same resources (food, rare materials and money), regardless of the unit.	Researches require different resources depending on the production cost of a unit.

Unit Balancing

	Call of War Classic	New Call of War
Unit roles	Most units share similar roles in the game.	Unit statistics have been changed for all units. Many units received distinct roles and are useful in different situations. A more distinct rock-paper-scissors balancing is in place. The unit description in the unit details provides hints how to use a unit.
Doctrine differences	No Doctrines, unit statistics are the same across countries.	Each country belongs to one of four Doctrines, which results in changes to unit statistics. On top of general buffs and debuffs that are applied to all units of a Doctrine, certain iconic units receive additional buffs to their statistics depending on the Doctrine.
New units	A smaller set of regular units is available.	Several new units have been added exclusively to the CoW 1.5 version, for example the Flying Bomb, Attack Bombers, Rocket Artillery and SP Rocket Artillery.
Nuclear units	Nuclear Battleships, Nuclear Aircraft Carriers and Nuclear Submarines are available in the game.	Nuclear sea units have been removed from the game for more historical consistency.
Unit abilities	Less unit abilities.	Several units have new and altered abilities. Paratroopers can be converted back into a plane after dropping on a province, Rockets and Flying Bombs now deal damage to friendly units as well but don’t ignore protection values anymore, Commandos now ignores protection values, several units receive full or terrain based stealth abilities, several units receive scout abilities against hidden land or sea units (see below).
Stealth and Scouting	Stealth: Submarine, Scouts: Naval Bomber	Stealth: Submarine, Commandos, Stealth on specific terrain: Militia, Paratrooper, Anti Tank, Tank Destroyer, Land scout: Armored Car, Motorized Infantry, Interceptor, Sea scout: Naval Bomber, Destroyer. Scout units only uncover stealth units that are on the same level or below.
Armor classes	Only one armor class exists for armored units.	The "armored" class has been separated into light armor and heavy armor, to enable more unit roles and counters.
