About This Game

WELCOME, UNIT!

Filthium Zero is a single-player action roguelite with a focus on verticality. Purge the Filthium-infested zones of Earth, take on hordes of mutants, engage in vertical and ground combat, and watch the ragdolls fly.

PURGE, SURVIVE, ADVANCE

Your mission: purify water sources by extracting Filthium and depositing it into Collectors, while defeating the hordes of zombies and mutants. Each deployment is a new UNIT soldier, armed with upgrades their predecessors secured. Gather resources, improve survival odds, and push UNIT’s mission forward — one soldier at a time.

FAST-PACED GROUND & VERTICAL COMBAT

Bounce off slimes to launch into the air, throw your barrel from mid-air for a heavy impact, slam down with force, and send ragdolls flying in every direction. Activate and combine powerful abilities, collect resources, and customize the next UNIT with a growing arsenal of upgrades.

THE SKULL

Every UNIT is guided by a strange, floating skull — a persistent assistant who remembers every fallen UNIT. It knows more than you might expect and never leaves your side.

💀 DEPLOY NOW, UNIT!
