Despite fears that some legal chicanery might delay its long-awaited release, id Software has declared that the DOOM 3 source code is available as of today. Now you can make your own games about spider-legged heads and eye-less penis monsters!

The source code is released with some recoding of the shadow tech, a move done to stop lawyers worrying about a patent issue. That aside, the code that made DOOM 3 one of the scariest shooters ever (I still find it terrifying) is now available right here.

Let's all make videogames, guys!
