This pack is an add-on for Halo 2 with a collection of multiplayer maps for gamers who do not have access to Xbox Live. It contains 9 new maps (Containment, Warlock, Turf, Sanctuary, Gemini, Relic, Elongation, Terminal and Backwash), an auto update that brings the game to the latest version, with cheating countermeasures, and all prior Live updates.
The disc also contains a bonus cinematic that showcases unseen side events during the Old Mombasa mission of Halo 2 and a behind-the-scenes documentary containing interviews with the designers about the inspiration for the new maps.
