I'm still trying to beat Halo 3 on legendary, and it's hard because now most of my friends are bored of it because they already beat the whole game 7 times.
I just have to beat "The Covenant" and the last level, "Halo".
There has been SO many FUCKING TIMES when I almost beat "The Covenant" with my friends, then someone leaves or fools off by TK'ing my and my other buddies that it completely derails our purpose of playing the level in the first place. So if anyone is available for finishing the game with me, add me to your friends list, and lets get this over with!
I'm also trying to get the "Your Show Sucks" achievement in Call of Duty 4, along with "Mile High Club".
