An Xbox Live Gold subscription does not grant you free access to purchase or download map packs for Call of Duty: World at War (often called "Call of Duty 5"). Gold provides the ability to connect to Xbox Live multiplayer servers, access party chat, and claim monthly free Games with Gold titles. However, all downloadable content (DLC)—including map packs—must be purchased separately with real money or Microsoft Points (legacy).
The Xbox 360 Marketplace was retired in July 2024. While previously purchased content can still be redownloaded from your download history, new purchases of Xbox 360 DLC are no longer possible through the official store. Physical disc owners who never bought the maps are now unable to acquire them legitimately.
