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.
I remember playing this in 2011 with mixed feelings.
I can say that I have better feelings for it now after playing it again.
The design in the first few maps was decent enough, with some levels including level-made furniture which reminded me of some of the better maps in the WC-mappack. Not to mention the gameplay itself was fun enough.
However, it got worse as the game went on, and the puzzles didn't exactly work for me in some cases.
However, I enjoyed many of the levels except the ending ones where it looked like the mapper got lazy, and the I felt more fatigued as I kept playing what seemed like increasingly boring maps.
However, It ended on a high-note with the secret arena level that gave me some more of a rewarding ending, even if I couldn't use the secret HEV suit for long.
Not bad, but it certainly could have been better.
