Doom 3 BFG Edition (stylized as D00M 3 BFG EDITION) is a re-release of Doom 3, which was released on October 15, 2012, in Australia, October 16, 2012 in North America, October 19, 2012 in Europe, and November 22, 2012 in Japan for the PC, PlayStation 3, and Xbox 360. The BFG Edition features enhanced graphics, better audio with more horror effects, a checkpoint save system, and support for 3D displays and HMDs. The game also includes the previous expansion Resurrection of Evil and a new single-player expansion pack called The Lost Mission. Additionally, it includes copies of the original Doom (the Ultimate Doom edition with the add-on fourth episode, "Thy Flesh Consumed"), and Doom II with the expansion No Rest for the Living, previously available for the Xbox 360. The BFG Edition also features the ability to use the flashlight while holding a weapon, in the form of the so-called armor-mounted flashlight. The PC version of Doom 3: BFG Edition requires the Steam client and a valid Steam account for installation, play, and achievements. The source code of Doom 3 BFG Edition's engine was released under the GNU General Public License in November 2012. Id Tech has announced that DOOM 3 BFG Edition will be coming for Nvidia's Shield Console and will be released along with the console. It will be running on 1080p at 60 frame per second. It was announced in April 2016 that Doom 3 BFG Edition was now playable on Xbox One via its Backwards Compatibility feature.
The Lost Mission takes place in the mid-level called "Enpro Sector" while the Doom 3 marine is escaping from the Enpro sector at the end of the level. The player takes the role of the last surviving member of Bravo team, which was seen being ambushed by demons in Doom 3. The Bravo team survivor is contacted by Dr. Richard Meyers (voiced by Paul Eiding), a scientist working on teleportation experiments in Exis Labs, and asked to help Meyers destroy an experimental teleportation array that was captured by the demons and is currently held deep inside Hell. The array is potentially powerful enough to send an army of demons all the way to Earth, hence Meyers' desperation to destroy it. To achieve this goal, the marine must acquire the components necessary to activate the Exis Labs teleportation system, then travel to Hell in order to destroy the teleportation array. In the epilogue, the marine is teleported by Dr. Meyers back to Mars. The reinforcements from Earth arrive to search for another marine who is still missing; eventually, they find him in the Delta Labs complex.
The game received mixed-to-positive reviews. The updated graphics, sound design, and inclusion of the new Lost Mission content were praised. Criticism was directed at the BFG Editions's long load times, forced auto-saves, and control scheme which forces the player to cycle through their weapons continuously in order to access a particular weapon - a feature deemed extremely inappropriate given the game's suspenseful, action-oriented gameplay. The controls overall were considered a step backwards due to the previous generation ports of Doom 3 allowing players to assign weapons to hotkeys. The inability to toggle back to the traditional flashlight mechanic of the original game was also criticized.
