About

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

a cool 2D shooter against alien monsters, the game was fast enough, it was exciting, the level system was well thought out
有成就 没中文 生物残次品 你是一个错误,一场脱离计划的实验产物,一件失败的生物造物。 在一座游走于生死边缘、进行隐秘实验的秘密实验室中,异变悄然诞生。你是一只无固定形态的寄生怪物,唯一的能力就是附身人类,将他们的躯体当作武器、工具与消耗资源。 《生物残次品》是一款黑暗世界观的动态横版平台跳跃游戏。这里没有身披铠甲的英雄,只有你、你的猎物,以及你一心逃离的渴望。 可附身关卡内任意 NPC 失去躯体并不代表消亡,你只需寻找新的宿主 每个人都拥有专属属性与武器 可随时切换附身躯体 依靠选择合适的身体,完成平台跳跃与解谜流程 整体画风阴郁压抑,无鲜亮色彩
It’s simple, a bit brutal, but really satisfying once you get into the flow. Definitely worth trying if you like platformers with a twist.

You possess people at each level. Each has their own gun and stats. Switch bodies, solve puzzles, and defeat enemies. The style is dark, dynamic, and not drawn out.
A stylish 2D platformer in which you play as one of the experiments and have to escape from a secret bunker. The main feature of the game is the ability to possess various enemies. AND IT'S FUN!
I had fun playing Bio Fail. The game has a weird and chaotic style that makes it memorable, and the atmosphere keeps you interested. Some moments are genuinely funny, while others feel tense and unpredictable.
Круто! На фоне игр, которые сплошняком напичканы всякими механиками, эта игра заставляет расслабиться от подобного перегруза. Напоминает флэш игру из прошлого и для меня это только ностальгический плюс
it's something with something ! it reminded me of the good old games ! at the beginning, the enemies are easy, but the more you progress, the more difficult they become ! +1 to my collection of games I've played!
The unique mechanics is that the player does not have his own form. The main gameplay is based on inhabiting people's bodies, using them as "consumables" to overcome obstacles, solve puzzles and battles.
