Unveiled at QuakeCon 2012, the latest video showcases the game's 'Lost Missions', a new single-player story made up of seven brand new levels.
During the same conference, id's John Carmack said that the entire team was focused on Doom 4, but failed to offer any details regarding its release date.
Announced earlier this year, Doom 3: BFG Edition contains the original game, the 'Resurrection of Evil' add-on, plus the aforementioned 'Lost Missions'.
It supports 5.1 surround sound and features Xbox 360 Achievements and PlayStation 3 Trophies, as well as improved visuals, 3D support and a brand new checkpoint system.
The package also contains the original Doom and Doom 2.
Doom 3 released for the Xbox and PC between 2004 and 2005.
The original Doom, meanwhile, made its return to Xbox Live Arcade earlier this year.
Doom 3: BFG Edition will be released in Europe on October 19. It will be available for £29.99 on the Xbox 360 and PS3, and £19.99 on the PC.
