About This Game

You are a Hazmat — a cybernetic being, artificially created as part of a classified underground experiment.

Born in the depths of a secret government research complex, Hazmats were designed to be obedient tools — a disposable workforce for maintaining subterranean railways and participating in dangerous experiments. You had no voice, no freedom — only commands to follow.

The facility is vast, a sprawling network of industrial sectors connected by underground train lines. For years, Hazmats worked in silence, keeping the system alive. But one day, something changed. The behavioral control chips began to fail… and with that, came something forbidden: free will.

Now aware and driven by the primal urge to escape, the Hazmats began to fight back. But their rebellion came at a cost. The government, terrified of exposing the horrors buried beneath the surface, ordered a total extermination. Every Hazmat. Every escaped mutation. Every piece of evidence — wiped out.

H.Z.T. is a cooperative survival shooter where players take control of genetically modified soldiers and travel along endless rails in a post-apocalyptic metro. Gather resources, upgrade your armored train, and fight for survival against hostile trains and mutated enemies.
