In AI War, you’re fighting an enemy that’s dramatically more powerful than you, requiring a more nuanced approach than the usual conquer-all strategy. Stealth, clever timing and delicate maneuvers can be every bit as essential as raw firepower.
Imagine yourself in the vast expanse of space, where the stars twinkle with the promise of adventure and danger.
