a long time ago this game was just a rumor then,a trailer was leaked out.We figured out at E3 2009 that it wasnt just a rumor or a trailer,that it was about a lone ODST that was struggling to find his squad in the night of New Mambassa.When Joe Staten of Bungie studios showed the first gameplay that was mind bottling for a halo game,it was amazing.It had a new co op mode firefight that is 4 players that fight off waves of covenant,every wave has a skull like at the first wave tough luck is turned on.This game is now a most wanted game of 2009 with its all 24 maps of halo3,but 3 more new maps longshore,citadel,and heretic,so go out and pre order it to unlock sgt johnson playable in fire fight,and dont forget to get this game september 22nd!
