Bum Simulator is a sandbox action-adventure game developed by Ragged Games. Players engage in survival mechanics, craft potent drunk potions from scavenged materials, and utilize a sentient shopping cart companion named Carl for inventory management. The game includes a storyline populated by eccentric characters, such as mutant sewer rat people and a mentally unstable clown. Players can also build, customize, and defend cardboard bases from rival gangs.

The game allows for creative combat through throwing explosive pigeons and features fully voiced dialogue to enhance its atmosphere. Players can recruit other bums to assist with tasks, construct shelters, and cultivate resources for base expansion and upgrades.
