Gun Monkeys is a multiplayer side-scrolling shooter game developed by Size Five Games, available for Windows. The game features monkeys with guns competing against each other in procedurally generated arenas that contain environmental hazards. The gameplay is skill-heavy, tactical, and most importantly, fun. However, the game was criticized for its difficulty in finding other players in the online multiplayer mode, which resulted in it being removed from Steam.

The game was initially priced at $9.99, but due to various problems, the price was dropped to $5.99, and it was bundled with another game as a gift for a friend. Critics had mixed opinions about Gun Monkeys. While everyone appreciated the gameplay aspect, they also criticized the difficulty in finding other players in multiplayer mode.
