This game is great, truly. The difficulty curve is insane compared to other classic FPS games, I do not recommend playing this on Extra Crispy at all since it just becomes so hard it isn't fun. I played it on Well Done, and it's really an experience. Episodes 1, 2, and 4 were amazing, creative maps that fit and play very well. Episode 3 I'm personally mixed on, it felt way too long though I still very much enjoyed it. The weapons and enemies forced me to play differently compared to other usual FPS games, and I love the way it was done. This is a staple, and a must play for boomer shooter fans.
