Doom 3 Source Code Released November 23, 2011

As John Carmack has promised for several years, the source code to Doom 3 has been released with the help of Timothee Besset.

Doom 3 was released in 2004 and was at the time considered to be one of the best looking graphics engines of its day. Since then, graphics engines have improved, but Doom 3’s unified lighting and shadowing system still holds up today.

Doom 3 wowed everybody when it first came into the spotlight at E3 2002, but I had been eagerly awaiting it for the entire four years it was being developed.  The morning it was released I intentionally took an early shift at work just so I could have a break when the stores opened.  I had preordered it at three different locations because they had three different preorder incentives (which were little pewter figurines of the original Doom enemies).  I had no idea one of the stores I preordered at just so I could get one of the figurines would be the place I would actually pick it up from!  When my boss saw what I was playing on my computer during lunch, instead of repremanding me, he sat down just so he could see how the game looked on my computer!

The code is released under the GPL. If you intend to modify it to create your own product with it, you MUST release it under GPL and include your source code with it.  According to the terms of the source code, no game content is included with the code, as that is still protected under the game’s EULA.

Give the code a download here!  This code is literally a huge footprint in the history of gaming and should be seen by software engineers and coders everywhere!
