my only gripe with this game is that it's short. i really enjoyed every second of it and wanted it to keep going. it's as if the devs for chasm: the rift went back to clean up their original game, improve upon the combat and level design, trim off all the fat, and were thinking of doom 3 while doing all of that. if you like chasm: the rift and/or doom 3, this is a no brainer to get or at least check out.
