8-Bit Invaders! is a sci-fi themed real-time strategy game by Petroglyph, pitting the human Galactic Marine Corps and the alien Cranoids against each other.
The game is a retro-style RTS with voxel graphics and a Command & Conquer style interface, it is cross-compatible with Petroglyph's previous 8-Bit Armies and 8-Bit Hordes in multiplayer, and owners of the other titles unlock their factions in skirmish mode.
