I remember coming down to see my bro playing it since he had the console(I had a gamecube) and he was saying i had to play it. So we start a co-op and yeah...the hallway and me going "wtf!! so many of them!! What level is this on?? How do I reload"......then later going "wait, i thought the bad guys were the elite? WTF is the flood? are they on the same side?"
Anyways i didn't get into it since i worked alot and only later before Halo 2 doing LAN parties. Damn was that fun. I still rememeber the guys at college when they got the "french version"....nobody went to sleep anywhere.
