343 Industries has announced that they are adding a new type of REQ pack to Halo 5: Guardians, and that it's going to cost a chunky $25 (or regional equivalent).
The new Arena REQ packs will be available from February 16 onwards, and they're going to include two Premium packs every week for seven weeks (making fourteen all told).
The items inside these packs will include random cosmetic items and, as the name implies, they're primarily aimed at Arena players. Players will be guaranteed the complete Mark V Alpha armour set, so if you want to look like Master Chief circa Combat Evolved, now you know how. The bundle can only be purchased once per XBL account.
