About this game
Description
Supplied by the Steam store
Overview
A mutagenic virus has spread across world, transforming the infected into deadly zombies and mutant creatures. Humanity’s last hope lies in small outposts equipped with purifiers — devices that release cleansing fumes to neutralize the airborne virus.
Command a squad of survivors in this minimalist top-down action RTS. Defend each base from waves of enemies. Every level is a fight to keep the purifiers running — and stay alive.
Unique Levels
Each level features a different layout and challenge. Purifiers attract enemies — you must protect them to survive and win.
Strategic Skill Tree
Unlock a wide range of upgrades that shape your tactics and offer new ways to play.
Weapons & Items
Weapons and tools are limited. Use them smartly to overcome each level.
