This is a very good first person shooter/horror game. Enjoy your first time playing this game, take your time. This has to be the most immersive game that I played so far (didn't play CoP yet, going to next). Exploring the Zone is fun and horrifying at the same time since you don't know what will happen next. There maybe a person who you'll meet in your first play through, and in the next, you might not cross paths with them because every character can be killed by the Zone.

The game did have a few crashes and ha;f way through I had to install the ZRP mod to fix a quest glitch, but never used anything else that the mod provided. If you want, for your first play through, consider installing this mod since it's the closest to vanilla SoC, but it's not necessary.

I really enjoyed this game. Just a warning, you'll die a lot in this game, so consider quick saving often (like every 30 seconds to a minute). If you want to continue playing, even after you finish the game, then download ZRP with a new game save since the vanilla game won't let you leave the final area (unless there is a way to leave in vanilla, but I heard there is not unless you download ZRP).
