Next to the original features this port introduces a new shotgun weapon (singleplayer as well as for the Soldier and Engineer in multiplayer games), new equipment (Holy Cross, EMP Device and X-Shield), and new enemies (Occult Priest and X-Shepard). Multiplayer games support a split-screen two-player co-op mode, and matches with up to sixteen players through a system link or over Xbox Live. Downloadable content is also available. As a bonus, a fully playable version of the original Wolfenstein 3D can be played.
