Survivors Under Siege Demo

A mutagenic virus has spread across the 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. Defend each base from waves of enemies. Every level is a fight to keep the Purifiers running — and stay alive.
