A few hundred condemned criminals were being shipped to the Auriga system on board the prison hulk "Success". When the ship crashes on the mysterious planet Auriga Prime, the survivors find themselves trapped in an ancient, sprawling facility built by the long-lost Endless civilization. To escape, they must protect the ship's crystal generator and fight their way to the surface through an ever-expanding, deadly dungeon.

The game is a unique hybrid of roguelike dungeon crawling and tactical tower defense. Players must form a team of heroes, each with distinct abilities, and carefully manage resources like Industry, Science, and Food. The core mechanic revolves around opening doors into unknown rooms, which can reveal valuable loot, merchants, or waves of terrifying monsters. Players use a scarce resource called Dust to power rooms and build automated defense modules to hold off the alien hordes. The Apogee Edition represents the definitive mobile experience, incorporating a revamped interface for touchscreens alongside all five original expansion packs: Deep Freeze, Death Gamble, Rescue Team, Organic Matters, and Bookworm.
