About Filthium Zero
Filthium Zero is a compact action roguelite in which you fight across the ground and through the air to purge Filthium-infested Earth. Each deployment sends a new UNIT soldier into corrupted zones to extract Filthium from the water, deposit it in Collectors and battle hordes of zombies and mutants.
Fight in the air and on the ground
Bounce off slimes to launch yourself into the air, throw your Extraction Barrel down for a heavy impact, or slam into the ground with force. Combat sends ragdolls flying, and you can activate and combine powerful abilities.
Upgrade each UNIT
Collect resources and unlock upgrades to improve your chances of survival. Each new UNIT soldier carries upgrades secured by their predecessors, letting you build on their efforts and advance UNIT’s mission one soldier at a time.
