This add-on package for the best-selling Halo 2 includes nine new multiplayer maps, along with a documentary featuring interviews with the designers, suggested strategies, and video fly-throughs of the new areas. An animated short that expands on the plot of the single-player campaign is also included. The disc's nine new maps are also available to Xbox Live subscribers for purchase and download online. While expansion packs for popular PC games became commonplace over the previous decade, the retail release of this Halo 2 Multiplayer Map Pack is among the first of its kind for a console game. ~ T.J.
