This game lived up to the promise of being difficult. I enjoyed my 90's shooters and I don't ever recall running in to a game quite this challenging. If you enjoy the challenge and facing perma-death then this is probably for you. If you enjoy making steady progress in a game and seeing it through to completion you may be infuriated in a keyboard-thrown-through-your-wall type of way. The soundtrack is pretty awesome as well and definitely worth the upgrade to the millennium edition.
