Concurrent Steam players, not daily or monthly active users. Console and other launchers are excluded. Peaks cover GaugeDB’s recorded history.
Imagine that you fell asleep in a quiet old hotel, and woke up in a completely different place, all the inhabitants of which want to kill you. Creatures hiding in the dark, strange shadows, heartbreaking screeching. You will have to face the unknown mechanisms and try to get out alive.
