SOMA
It would have been easy for Frictional to follow up Amnesia: The Dark Descent with yet another first person horror title but SOMA is something deeper. The sense of mystery and befuddlement is stronger as protagonist Simon explores the underwater lab of PATHOS-II with no memory of how he got there. Despite the presence of terrifying robots, the secrets of PATHOS-II unfurl, revealing a dark sci-fi fantasy with some interesting moral implications.
