A Call awakens you from ages of dormant sleep into a world that has been shattered — its reality corrupted, its landscape poisoned by horrors drawn from the deep edges of the cosmos. Venture alone or join allies online as you traverse this wicked terrain. At the center of your survival is the RailGod: a colossal nightmare creature fused with the body of a locomotive, serving as your base, your weapon, and your home. Build upon the train as you move, craft weapons, harness dark magic, gain eldritch powers, and upgrade your Carriages to withstand the relentless waves of monsters and cultists. Stop at cursed locations to explore, fight, capture your enemies, and sacrifice them to whatever this world demands. Prepare well. The battles ahead will require it.
