or those of you Halo 4 fans who live across the pond, game.uk and gamestation.uk will be offering a another set of preorder bonus skins. Pre-orderers will unlock “customizable Oceanic Armor Circuit and battle rifle skins”.
The helmet looks like something you would see on an oldschool deep ocean diver suit. The battle rifle skin which they mention looks like the arctic skin we have seen from other preorder bonuses.
Credit goes to Josh S 95 on the Waypoint forums for finding these bonuses.
