Editor's take
The survivors-like entry: an arena, endless mutant hordes, and a roguelike upgrade drip where every level-up is a build decision. Toxic Arena runs the Vampire Survivors playbook competently — auto-attacking weapons, escalating swarms, and the specific euphoria of a build clicking at minute eight. The biological-catastrophe theme gives the mutants a coherent look, and the arena has enough geometry to make kiting a skill rather than a formality. Runs are long by browser standards; that's the genre contract. Desktop recommended for swarm visibility. Best for: survivors-like addicts and anyone who wants twenty-minute runs of escalating build power.
