It happened at the peak of the New Cold War. Out of nowhere, the giant Cubes appeared in the sky. Global superpowers mistook them as an escalation from enemy states, and soon, civilizations crumbled under nuclear warheads. Only a handful survived, and they buried themselves below ground and endured.

Several decades passed. When the survivors finally mustered up the courage and resurfaced, a Cube that was still in the sky swallowed them whole. Then someone made it back from the Cube. Their hands were full of supplies needed for survival. Every day since, humanity has looked upon the Cubes with fear and awe.

Desperate, the survivors headed for the Cubes, but most never returned. Now, it is your turn. Will you face the Cubes for a chance to live, or will you perish in the wasteland?
