Champions Bundle

The Champions Bundle was the fourth and final major expansion for the Halo 4 multiplayer experience. Developed by 343 Industries in conjunction with Certain Affinity and Digital Extremes, the bundle includes three packs, the Bullseye Pack, the Infinity Armor Pack, and the Steel Skin Pack, and was released on August 20, 2013. The expansion includes 10 new achievements and 250 Gamerscore. Unlike the other map packs, the Champions Bundle was not a part of the War Games Map Pass, and was launched individually for 800 Microsoft Points. Each pack can be purchased separately at lower prices, however, purchasing the bundle as a whole will unlock exclusive content. On July 7, 2017, along with all other Halo 3, Halo 4, and Halo: Reach DLC map packs, the Champions Bundle was made free to those on Xbox Live.

The weapon skins and armor permutations available with the Champions Bundle were not included within the Halo 4 component of Halo: The Master Chief Collection at launch, though the two maps and Ricochet gametype were. The launch of Series 4: Reclaimer in November 2020 saw the inclusion of all armor and weapon skins from across the bundle's various components within the collection, with 343 Industries expressing interest in bringing the Bullseye Pack and Infinity Armor Pack permutations to the game as well. This interest was later expressed with the Flighting release for Series 7: Elite, seeing the four armor permutations available for use as part of the collection. The Resistor Tactical Package initially was not available in The Master Chief Collection before it was added in the December 2022 Update.

Production notes

 * During the “What’s Next: Halo 4 Summer 2013″ panel at RTX 2013, 343 Industries' promotional art for the bundle featured the "Bones" and "Striped" M395 DMR weapon skins as part of the content update's bonus content. The "Bones" skin would later be relegated to a code found with the CIO Spartan in Series 2 of McFarlane's Halo 4 line of figures, while the "Striped" skin could be unlocked through earning certain achievements in Halo: Spartan Assault.

Miscellaneous

 * The first trailer for the Champions Bundle DLC shows PREFECT-class Mjolnir with a different skin pattern on the armor's wrists, an added decal on the helmet's forehead, and the player's secondary color applied to their player model's fingertips. These would be altered for the DLC's launch.
 * Champions Bundle DLC items, including the new armor sets, weapon skins, and the Resistor tactical package, do not appear in Spartan Ops. Instead, weapons revert to their default appearance and armor pieces are replaced by Recruit armor. Equipping Resistor causes the tactical package to automatically revert back to "None".
 * Since the release of Season 4 in November 2020, these weapon skins are available in Spartan Ops in Halo: The Master Chief Collection.
