campaign in Halo is what is should be, mindless action with a lot of explosions, cheesy dialogue, more explosions. anyone who picks up a Halo game for the story deserves to be disappointed, it's a generic FPS, it's just that Bungie has done it right every time. I played through the campaign solo the first time, and I'll probably go through it again on Legendary with a friend or two. there was no epic plot twist, or extremely well written characters, but there were a couple of "oh shi** that was awesome" moments and that's why the Halo games are fun. you pick it up, you kill some aliens, you drive some sweet vehicles, and all this is even more fun when done co-op.
