SOMA

SOMA is a sci-fi survival horror that makes you rethink the description of death. You play as Simon Jarrett who was injured in a crash accident and agreed for an experimental operation on his brain. He wakes up at an abandoned underwater facility full of mutants. Trying to figure out what’s going on, Simon finds Catherine Chun, a scientist, who tells him about the technology of copying the human personality.

The gameplay is based on exploration and puzzle solving. There's no combat, and you are meant to avoid enemies and act stealthily. To progress through the story, you need to search for clues, read multiple notes and solve puzzles.
