Call of War is a strategic MMO game set in Word War 2. Starting as one mighty WW2 nation, you expand your empire by battling other nations and strengthening your own defenses. Fans of RISK and Axis & Allies will enjoy the pace of this MMO.

How to Play Call of War

Call of War is an MMO strategy game that puts you in control of a country and its resources. There are many strategies you can use to play the game. Will you play aggressively for world domination, or will you be defensive and protect what you have? It's up to you.

Long-Term Gameplay

To build your military powers, recruit new units. As you progress, you can upgrade buildings, train your army, and research new technologies to crush your enemies. These huge MMO games can progress for weeks as mighty nations become more powerful and smaller nations are squashed.

Markets and Resources

Each country has natural resources that are vital for success, but they can also be exploited by rival forces. Your precious resources are used to build new technologies, upgrade buildings and feed troops so they get stronger. There's also a market for trading goods, which can be useful if you don't have the resources you need. Build your defenses to secure your resources and look for weaknesses in rival factions.

How to Win the Game

In the end, countries with top-secret weapons and nuclear technology will be the strongest and most feared. The winner of the game will be the first person to reach 60% of all Victory Points (VP). These VP are awarded through taking control of enemy provinces.

Call of War Tips


A defensive strategy may work well for beginners. Fortify your borders in key areas. Place units all around the border too. Play as a country with fewer borders where possible, this makes it easier and cheaper to defend.


Attack and ruthlessly expand your holdings. Start by building your military and put everything you can into building stronger forces. Attack capital cities to be rewarded with Victory Points and resources to gain an edge over the competition. Be careful, too much attacking without a solid defense could be your downfall.


Make sure you're researching new technologies. These technologies can take days to develop so start developing them as soon as possible. Powerful weapons and units are the secret to building an unstoppable military force.

Form Alliances

It's important to have allies in times of war. Send messages to neighboring countries to try and form an alliance. Diplomacy is an invaluable tool that will help you build more powerful armies to conquer other players.
