I miss that game. When it came out it seemed like there was nothing else like it. I loved taking long range sniper shots, it was cool that you could just barely see the people, or not even see them, and fire at them in those guard towers.
I liked playing against my 2 friends, but I'd kick their ass because they didn't play much. It was usually both of them against me. I remember they were in that one room that was like a big control room with monitors everywhere, hiding behind pillars and stuff, and I was coming down those stairs and peeking into the room through the big door, and they'd shoot at me. I remember poking out for a second and firing two shots from my PP7 pistol or whatever and headshotting both of them dead, and they swore I was cheating some how, but I kinda got lucky. hehe.
