Toxic Arena: Biological Threat
About Toxic Arena: Biological Threat
You fight for survival in Toxic Arena: Biological Threat, standing alone against endless waves of mutants in a contaminated arena. Move constantly to dodge attacks while your weapons fire automatically at the nearest threats. Each kill drops experience orbs that level you up and let you pick powerful mutations—boost your damage, speed up your fire rate, or unlock special abilities like ricochet shots and armor piercing. The longer you survive, the more overwhelming the mutant swarms become, forcing you to adapt your build on the fly.
Every run on Poki Games tests a different strategy as you balance offensive upgrades against survivability perks. The mutation system means no two attempts play alike, and chasing your personal best time becomes addictive as you discover which ability combinations work against the toughest late-game hordes.
