Doom 3: BFG Edition

Doom 3: BFG Edition was a remastered version of Doom 3 which was released to celebrate the 20th Anniversary since 1993.

John Carmack, id's technical director (and Doom's co-creator), said in a press-release, "DOOM 3 was enthusiastically embraced by gamers worldwide. Today, the full experience has been enhanced and extended to be better than ever, and is delivered across all platforms with a silky smooth frame rate and highly responsive controls. New support for 3D TVs, monitors, and head mounted displays also allows players to experience the game with more depth than ever before. We think shooter fans everywhere will love it."

The BFG Edition included:
 * The 2004-era "Doom 3" with enhanced graphics, a checkpoint save system, 3D Capability for 3D Televisions and Achievements(Xbox 360)/Trophies(PS3)


 * The already-released add-on; "Doom 3: Resurrection of Evil"

Unlike the original game which featured the Flashlight as a 'weapon' itself, the BFG Edition instead was 'armor-mounted' meaning players can attack and illuminate dark areas simultamiously.
 * The Lost Mission 8-level campaign, which was cut from the original game
 * Ultimate Doom
 * Doom II: Hell on Earth, including the "No Rest for the Living" Doom 2 Expansion recently released on Xbox Live.

Late November, the GPL version of the Doom 3 BFG Edition engine was released on GitHub.

The .WAD files for the BFG Editions of Doom and Doom II do work with source ports like Zandronum and ZDaemon as well as with Doomsday and ZDoom. The Doom II expansion "No Rest for The Living" also works on these source ports when using Doom II as the main WAD and the NERVE wads used for the map information.
