Oooh that's nice. I'v played it waaay to much to hehe. Really? Me to acctually, the story was way off from Halo: CE and it did not live up to the expectations of a Human - Covenant war on Earth, way to short stay there.
You should try it. Halo 3 is back on track in the storyline and fixes the mess Halo 2 made to it. Love the Human - Elite Alliance in Halo 3. One of the possitive effects from Halo 2 I guess hehe.
Woho! You will not be dissapointed. I love Halo 3, not becouse of the Multiplayer but for the Campaign and story. There is so much mystique about the Forerunners and their structures wich facinates me. And besides, you get to know some more interesting stuff about them in Halo 3.
