About Instant War

Join an alliance and defeat your opponents, using a large action panel available: army reinforcement, battle tactics, real-time strategy, assault forces, drone and even airstrike. In this 4X game, you can fight for strategic territories or resources points. Choose wisely how to manage your resources and massive army in order to defend your base from the other players.

Games like Portal 2, where one idea carries the whole game
