Bioweapon Demo

Click on the banner above to follow this game on Kickstarter. I will be launching the campaign soon, with lots of bonuses for supporters.
Please be patient when loading - the game is 250mb!
You can play this game with a gamepad or mouse and keys. Mobile isn't supported right now though I might add that at a future date.
Bioweapon is a fast, gritty retro FPS where you battle through a doomed desert town overrun by the infected. This single‑player demo drops you into the first handcrafted slice of the chaos—an atmospheric, VHS‑soaked battleground crawling with the undead.
My main inspirations are George Romero zombie films and the Left 4 Dead and World War Z video games.
Armed with the experimental Uni‑Gun™, you’ll scavenge anything you can find and fire it back at the horde. Every shot counts, every corner hides danger, and every run pushes you deeper into the nightmare.
The full version of Bioweapon will expand into a 1–4 player co‑op experience, complete with procedural arenas, escalating hordes, and a growing arsenal built for pure boomer‑shooter mayhem.
Features in the Demo:
• Gritty, single‑player retro FPS action
• The desert town of Nowhere, now a feeding ground for the dead
• The versatile Uni‑Gun™, capable of firing any ammo you can scavenge
• VHS‑apocalypse atmosphere with crunchy gunplay and tight pacing Survive the swarm.
Master the Uni‑Gun. Sign up for the kickstarter to join the co‑op carnage to come:
