—Bio Fail is a dark 2D platformer where you play as a biological anomaly—a monster that possesses humans. Control their bodies, fight your way through levels, solve puzzles, and destroy everything in your path. One body—one chance
Bio Fail
Steam
You are a mistake. An experiment that didn’t go according to plan. A biological failure.
In a secret laboratory where experiments were conducted on the edge of life and death, something emerged. You are a parasitic monster without a fixed form. Your only ability: to possess humans and use their bodies as weapons, tools, and expendable resources.

Bio Fail is a dynamic side-scrolling platformer set in a dark world. No heroes in shining armor. Just you, your victims, and your thirst to escape.

✅ Possess any NPC on the level
✅ Losing a body ≠ death—you simply search for a new victim
✅ Every person has a unique set of stats and weapons
✅ Switch bodies at any time
✅ Platforming + puzzles through choosing the right body
✅ Gloomy visual style without bright colors
