This is the first time ever that the serialization of a full retail game will be available for purchase through Xbox Live® Marketplace. The game will be available in four episodes; Episodes 1 & 2 will be available in September, with the next two episodes arriving shortly afterwards. A full retail version is planned to be released for Xbox 360 later in the year.

In order to access Lara Croft Tomb Raider: Anniversary downloadable episodic content for Xbox 360, players will require a Lara Croft Tomb Raider Legend disc. The episodes will cost 2400 Microsoft points for all four episodes, and will be released in two separate launches. Episodes 1 & 2 will be released in September and episodes 3 & 4 will follow shortly afterwards. The Croft Manor level will be free to download with both sets of episodes. Additional Tomb Raider Anniversary downloadable content will also become available for purchase on Marketplace to support the launch of Tomb Raider Episodic such as picture packs and theme packs.
