From Press Release:
Isolated, submerged in the ocean’s darkness, chaos has overtaken the halls of PATHOS-II, and the boundaries of humanity strained beyond repair. From Frictional Games, creators of the critically acclaimed Amnesia series, SOMA is coming to Xbox One on December 1st with the addition of Safe Mode.
Safe Mode introduces an optional new way to play SOMA in the Xbox One and PC releases. Protected from the hostile creatures below, let yourself sink into the mystery and atmosphere of PATHOS-II as you uncover the truth and determine the fate of the station.
SOMA is coming to Xbox One on December 1st and is available to pre-order now. Safe Mode will launch simultaneously as a free update for PC, and will be available for PS4 at a later date.
