Best scary, horror, or otherwise Halloween-themed games!
Okay, so this in inspired by TomxJ's post in another thread. I think it would be cool to have a thread listing the best options available for scary, horror, or just simply Halloween-based games, now that we are into October. I for one am a fan of the genre, but have probably missed out on many titles over the years.
This can include both full games and mods, but if you list a lesser-known mod, please specify the game for which it is a mod.
I'll start it out:
Resident Evil (series)
Dead Space (series)
Amnesia The Dark Descent
The Walking Dead
Cry of Fear (Half Life mod)
