Differences with Doom 3
Compared to the "normal" Doom 3, the BFG Edition features:
 * Doom 3: Resurrection of Evil bundled in
 * A new campaign, The Lost Mission
 * A checkpoint save system
 * Rebalanced difficulty, notably with greater amounts of ammunitions available
 * An "armor-mounted flashlight" which can be used alongside a weapon
 * More light sources in the levels
 * Higher resolution for some textures

The Lost Mission

 * Main article: The Lost Mission

The Lost Mission, like Resurrection of Evil, features another protagonist: a member of the Bravo Team that the hero of the original campaign was meant to rejoin. The primary objective is to shut down a teleporter to Earth to prevent the demons from using it.

Differences with Doom and Doom 2
The classic Doom content is available through three WAD files found in /SteamApps/common/DOOM 3 BFG Edition/base/wads; these are DOOM.WAD, DOOM2.WAD, and NERVE.WAD.

The Ultimate Doom

 * The pickup sprites for the stimpack, medikit, and berserk (STIMA0, MEDIA0, PSTRA0) are modified in compliance with the Red Cross' wish that its symbol not be used in games. Instead, the symbol is replaced by a red and white pill.
 * An M_MULTI menu graphics lump has been added, which reads "multiplayer".
 * M_GDHIGH reads "Fullscreen:" instead of "high".
 * M_SCRNSZ reads "Gamepad:" instead of "Screen Size".
 * Four new menu graphics lump are present: M_ACPT ("accept"), M_CAN ("cancel"), M_EXITO ("Are you sure?"), and M_CHG ("change game"). They have been inserted in between the DEMO2 and DEMO3 lumps.
 * The new DMENUPIC lump is present.

Doom II

 * The pickup sprites for the stimpack, medikit, and berserk (STIMA0, MEDIA0, PSTRA0) are modified in compliance with the Red Cross' wish that its symbol not be used in games. Instead, the symbol is replaced by a red and white pill.
 * Betray is present, though it is not normally accessible. The hidden secret level exit in MAP02 does not lead there.
 * The Wolfenstein SS sprites (SSWV*) are all replaced by copies of POSSA1 with bad offsets. Oddly, the offsets change for each sprite, even though none of them look usable. The last four sprites of the gib death (the S, T, U, and V frames) are unchanged, however.
 * The ZWOLF* texture with Nazi iconography (Hitler portraits, swastikas, imperial eagles...) now look like their unadorned counterparts. ZWOLF2, ZWOLF3, and ZWOLF4 look like ZWOLF1; ZWOLF6 and ZWOLF7 look like ZWOLF5; ZWOLF12 and ZWOLF13 look like ZWOLF11. The definitions in TEXTURE1 are identical, it is the patches that have been changed.
 * D_EVIL and D_ULTIMA are now copies of D_DOOM.
 * MAP31: Wolfenstein and MAP32: Grosse become MAP31: IDKFA and MAP32: Keen. The CWILV30 and CWILV31 lumps are changed to reflect this. All Wolfenstein SS have been search-and-replaced by zombiemen.
 * The new DMENUPIC lump is present.
 * The INTERPIC lump is used instead of the TITLEPIC.
 * The TITLEPIC lump, not used, is entirely missing from the IWAD. This creates a severe incompatibility with the original exe, as well as most source ports.
 * The M_EPISOD lump is used and reads "Which expansion?" instead of "Which Episode?"
 * M_EPI1 is used and reads "Hell on earth"; M_EPI2 is used and reads "No rest for the living". (M_EPI3 remains unused and still reads "Inferno".)
 * Four new menu graphics lump are present: M_ACPT ("accept"), M_CAN ("cancel"), M_EXITO ("Are you sure?"), and M_CHG ("change game"). They have been placed at the very end of the file.
 * CWILV32, MAP02, MAP33, MAP31, MAP32 are moved to after the F_END marker and before the four new menu graphics, in that order; instead of placed in sequence.

No Rest for the Living
The expansion pack lacks the metadata it had in the Xbox 360 port. This means that the sound track, par times, and level progression are unchanged from Doom II.
