Considering pre-ordering Halo 4? 343 Industries offers up this rundown of the pre-order goodies bonuses known as of this point.
These were posted over on the official Halo blog, where it was noted that not all retailers have specifically announced which of these items they’ll be offering as their pre-order goodies. So, for now, it’s more a rundown of what is being offered, and not specifics on where they’ll be offered.
Also, to be clear, the armor skins are just that—skins. The actual armor variants aren’t part of the pre-order bonuses, and will be part of what is naturally unlocked via gameplay. Even better, the skins themselves can be customized color-wise—so if you like a particular pattern but not its colors, you’ll be able to change it to your liking.
