Claustrophobia is an Action/Adventure/Puzzle type mod in which you play a rebel in the Half-Life 2 universe fighting and solving his way through areas to get to safety.
A fun mod to play. I felt some of the puzzles could have done with some clues.
I couldn't make it through some parts without noclipping. e.g. towards the end of the mod there should have been a Combine transport which bursts out of a garage. In the garage there was a force field switch I needed to turn off to progress. As the Combine transport didn't activate, then I couldn't enter the garage without noclipping into it.
Anyway, a good fun mod.
Cheers,
