About This Game

Step aboard a space train looping a dead sun in the EXO 15 System. Stop at abandoned waystations for supplies to build the perfect loadout. Fail to reach the front in time, and a great being will send you back to the beginning—loop after loop.

You’ll step into the role of the sole human operator on the train, tasked with caring for a shipment of Robotic Assisted Technology Servants (RATS). But whatever destroyed this solar system is spreading through them—and through the train itself. As the RATS turn hostile and the cars warp beyond recognition, you’ll have to fight, adapt, and uncover the truth behind the cataclysm that left EXO-15 in ruin.

Each run will take you closer to the front- and whatever might be there.
