SourceIcon.png This game has uncompiled source code.

In Eggy, the player controls Ena, a body armor that has to collect supplies while at the same time avoiding hits from tanks and saving humans from becoming evil undead cyborgs.

The game would later become the "mascot" for Project EGG, a subscription service that features modern-hardware conversions of old PC games.
