Frictional Games Forum (read-only)

I play Penumbra: Twilight of the Archaic and whenever I go through the vent, it crashes and telling me there's an error in my file, but I can't read the rest of it and it was too short to read.
Can somebody help me? (Sorry for my grammar)

Since that's a mod, you should ask the mod creator about this crash. It could be specific to the mod and not a game issue, so we may not be much help here.
