A retro arcade classic, pushed far beyond its roots.

Space Invasion Infinite takes the simple, satisfying formula of classic alien wave shooters and transforms it into a build-driven arcade survival experience. Hold the line, move left and right, and blast through endless invading waves — then reshape every run with powerful upgrades, brutal bullet effects, and game-changing augments.

Build your turret

Discover dozens of upgrades, branching upgrade paths, deadly projectile modifiers, and powerful augments that evolve the way your turret fights. Stack synergies, create broken combinations, and survive longer with every run.

Face escalating threats

Battle a wide variety of enemies with distinct attacks and behaviors, spawning in handcrafted wave combinations that keep every run unpredictable. Deadly bosses bring unique mechanics and punishing attack patterns designed to break your defenses.

Grow stronger over time

Unlock new turrets, higher difficulties, gameplay modifiers, and permanent upgrades as you push further and master the invasion.
