As promised, John Carmack, Bethesda, and the team at id Software have released the source code for Doom 3: BFG Edition with the latest update of the game for the PC. The code gives coders and gamers alike (as if the two things were mutually exclusive) a chance to play around with the code and pretty much do what they like with it. Making your own game out of the code is a distinct possibility, if you have the talent and willingness to learn how to mess around with it.
The source code is now available on GitHub for download.
Bethesda has written a lengthy blog post explaining what the new updates for the BFG Edition of Doom 3 bring to the game. These are as follows:
New features:
All projectiles cast shadows
Texture LOD bias added to menu options
Added option to force v-sync (instead of “smart v-sync”)
