About Instant War
Instant War is a multiplayer 4X strategy game set in 2040, after states have collapsed and war has erupted. New nations have risen from the Old World’s ashes as geopolitical superpowers, and an arms race is driving the development of AI-powered tactical weapons. You build your empire, discover secret weapons and command an army against other players.
Build your base
Personalize and expand your Headquarters, strengthen its defenses, and oversee military, medical, technical or A.I. research. You can also build a farming empire to gain an advantage over other players. Choose how to manage your resources and army as you protect your base from their attacks.
Command your forces
You can choose from more than 50 units, including tactical units, each with its own specialties, strengths and weaknesses. Use army reinforcements, battle tactics, assault forces, drones and airstrikes, and adapt your army and tactics to different situations. The battlefield’s 3D terrain can help you ambush opponents.
Alliances and events
Join an alliance, cooperate with other players and coordinate attacks, including night raids on enemy bases. You can fight for strategic territories or resource points and take part in daily events, including a PvE world boss, cross-server warfare and special events such as Halloween and Christmas.
