About the game
Two players share one screen and fight off zombie hordes from behind the shoulder, each as a mercenary.
Split-screen co-op with a view for each player. Over-the-shoulder aiming from survival horror. Horde-clearing waves from survivor-style games. A fast, casual pace for both players.
The creator wanted a couch co-op game to play with their wife.
