SOMA is an awesome narrative survival horror game heavily inspired by some of my favorite sci fi. It has some genuinely scary moments, and like the Amnesia series, you essentially have no defense against enemies - your only option is to run and hide. The developers added (again, post-release) a “safe mode” that allows you to experience the story without some of the scary bits. The enemies are still there, they’re just non-hostile.
I played through SOMA when it was released and replaying it (and trying out safe mode) are on my very long backlog, so while I haven’t tired this mode specifically, I can attest to SOMA being a really enjoyable and well-written game.
