IRON GUARD: Day Zero

Tower defense on an unknown planet

IRON GUARD: Day Zero is a sci-fi tower defense game for PC, set on an unknown planet where terraformer robots have rebelled. You defend the surviving crew and work to evacuate them, while uncovering why the robots turned against their creators.

Defenses and drone combat

You place upgradeable turrets, path blockers and mining harvesters to hold the line. At the same time, you fly an armed drone across the battlefield and shoot with conventional weapons or two superweapons. Five turret types can be upgraded, and equipment upgrades between missions are non-linear.
