Invasion Protocol — is a brutal top-down roguelite shooter where the player doesn't save a planet from invasion, but becomes part of a punitive operation against massive swarms of alien creatures. The landing begins in chaos: surrounded by bugs, acidic mutants, destroyed bases, and soldiers in skull helmets, ordered to simply purge all life from the surface. There's no time to hide here. Combat revolves around constant movement and precise shooting. There's no cover, no long firefights, or cautious waiting — enemies overwhelm you with sheer numbers and speed, forcing you to shoot on the move, break through crowds of creatures, and react instantly to new threats. A mistake quickly turns the screen into a bloody mess of explosions, acid spit, and monsters flying from all directions. Each class feels different. Some turn the battlefield into a minefield and choke passages with turrets, others rely on stealth and mobility, and still others simply charge head-on with heavy weaponry. During a run, you can swap out weapons and abilities right on the fly, adapting to new enemy mutations, mission objectives, and the next wave of chaos. Features of the game A hardcore top-down roguelite shooter. Classes with different fighting styles. Procedural missions and random events. Huge swarms of enemies and mutants.
