About this game

Toxic Arena: Biological Threat is a 2D single‑player shooting roguelike set in a collapsing arena during a global biological disaster. You control a fighter with WASD or arrow keys, fending off relentless waves of mutant enemies. Each minute brings a fresh wave, testing your reaction time and tactics as you try to survive as long as possible.

What keeps the gameplay fresh is the Deep Mutation System; after each wave you earn biological experience that lets you boost damage, fire rate, or unlock abilities such as ricochet shots and armor penetration. The game runs directly in your browser, is completely free, and works on desktop or mobile browsers without any download. Compete with friends for high scores and see how long you can hold the arena.
