WAIT!!!!!! I can only pick one? That's hard..... just about everyday back when i got halo 2 all my friends would come over to have a LAN party, we got so into it that we had my bed sheet hanging in the middle of the room so we couldn't turn around and screen watch. We also had so many people that we had to switch teams on and off, we use to have our own little tournaments too. Those where good times, but if you want my favorite moment playing a Bungie game then it has to be when my friend and i were just messing around on lockout and he was explaining to me how duel-wielding needlers were the best thing in the game that's when i threw a random sticky grande across the level and stuck him right in the face. We were laughing for at least 5-10 minuets after that. So many amazing moments happened on lockout it was hard to chose just one.
