Halo 3 is pathetic. I've never been a fan of Halo, but at least Halo 2 was justifiable. Halo 3 has nothing new to it.
Campaign: Halo 3's campaign is abysmal. Theres only 9 levels to it, and there aren't every any specified missions. Basically, the whole campaign is....kill an alien, kill another alien, kill more aliens, kill more more more aliens, kill aliens, KILL ALIENS....game over.
Multiplayer: The multiplayer is ok, except for the fact that it gets verrry boring after a while. The multiplayer does nothing to improve upon from what Halo 2 did, thus making it a failure.
Creating Levels: Not even fun whatsoever. Not only do you have to erase every little item in the game before you can start your map, but the system is very glitchy.
Story: The story EPICLY FAILS. There is no point to the story at all. Like I said......kill aliens. Thats the whole story. I really hate this game.
Last Word: The game is a complete letdown. I'll bet Gamespot was payed to rate it good by Microsoft. CHEAP.
