Developed by 343 Industries in partnership with Texas studio Certain Affinity (previously responsible for and the Halo 2 Blastacular map pack), the bundle adds the Steel Skin pack, Bullseye pack, and Infinity Armour pack.

Purchasing the trio as a collection adds bonus content, for more than 18 new in-game items. The bundle will retail for 800 Microsoft Points, and will be available from August 20.

The three packs will also be also available separately. Bullseye adds two new multiplayer maps, "sports-themed Spartan armour", and a new gravball game type called Ricochet for 480 Microsoft Points. The Infinity Armour pack contains new legendary Spartan armour, while the Steel Skin pack gives UNSC, Covenant, and Forerunner weapons a steampunk look. The latter two packs will sell for 240 MS Points each.
