In Dungeon of the Endless, the player takes the role of the survivors of a prison spaceship, its escape pod having crashed to the surface of a strange planet. To escape, they must take an energy crystal through several floors, each floor filled with a number of dangerous creatures. To help, the player can have their survivors explore the randomly generated levels to collect resources as to enable power to various rooms and construct turrets to fend off the enemies when they move the crystal from its starting point to the elevator to the next floor.

A few hundred condemned criminals were being shipped to the Auriga system on board the prison hulk “Success”. While this was presented as a chance to earn back their place in society by working hard for the common good, they understood that in fact they would be slave labour, sent to colonize an unexplored planet. All they knew about Auriga Prime was what the probes told them: it had water, temperate zones, plant life, and plenty of metals in the crust.
In fact, the planet Auriga once hosted a major settlement of the galaxy-travelling ancestors known as the Endless. In addition, the planet was still orbited by a functioning (and well cloaked) defensive system, which sprang eagerly to life upon the arrival of the Success. Within a few minutes, the ship was nothing but a few large chunks of metal falling toward the planet.
Every set of holding cells also functioned as an escape pod, so the ship let itself disintegrate and the surviving prisoners fell bruised but (temporarily) alive and (momentarily) safe to the planet below. Safe, that is, until they realized that they had crashed through some sort of facility of the Endless, down to a sub-basement so deep and ancient it might as well be called a dungeon…
