Tons of official Halo 3 news got released this week by Bungie and several media outlets. I let you check out IGN and Bungie for all their coverage, but I'll bring you some nice screens of some new maps and armor types.
This is one of the new armor types the chest, helmet, and shoulder plates are different. If you ask me he looks a little Boba Feta-ish to me.
Now this one is just god aweful, he looks like a bug, I'll enjoy killing people wearing this.
