Brainless is a 2D top-down single player action game in which you control a zombie horde that roams around turning humans into zombies. You begin with control of a single zombie, weak, vulnerable and hungry. You eventually spot a human and prey upon it. The dead human reanimates and joins your horde as a zombie. You've found a new friend. The cycle continues and your horde grows larger. As the game progresses you encounter stronger resistance, fortified strongholds and harder enemies.
