PC / Monolith Productions / 2005
Guessed by KLXVER
I'm not typically a fan of either horror or first-person shooter games, so for this one to be on my list is quite an achievement since it's both together. I just really enjoyed (well, kinda) this game when I got it back in the day, and it was really one of the most scary games I played - I went all the way until the end and it just kept getting harder and more terrifying all the time. It was intense throughout and somehow got me hooked despite having a super complex story I didn't understand a thing about.
