From the store page

GROUND ZERO APRIL 2026 SUPER DUPER DEMO The world ended. It got worse. Now it is somehow your problem. Dive headfirst into a radioactive dumpster fire of mutant chaos, cosmic nightmares, and government-level bad decisions in Ground Zero Hero Demo, a retro-fueled adventure where the apocalypse is equal parts terrifying, absurd, and probably avoidable.

Questions

Is it really free?

Yes. Ground Zero Hero Demo is free right now on Steam, with nothing to pay.

Is this the full game?

No. A demo is a portion of Ground Zero Hero Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.

Where do I claim it?

On the official Steam page. We link straight there — we never host game files or act as a middleman.
