Bungie have confirmed the existence of a SUROS Arsenal Pack. This offer will be available to all players outside the United States and is included in the pre-order of the $40 and $60 editions (not just the Collectors Edition.) If you have already pre-ordered a qualifying edition, you will receive this pack, too.
Included in the pack is a Suros shader for your characters, a Fire Emblem, an Auto Rifle, Pulse Rifle and Scout Rifle. The stats for each of these weapons is unconfirmed at this point.
