id Software recently released Wolfenstein 3D for the iPhone. This is fantastic news. The game that started the entire first-person shooter genre is now on the iPhone.
But there is more. id is releasing the source code for the game. (See link at the bottom of this page.) And John Carmack, the brains behind nearly every id project for the last several decades, wrote about his experiences with development on the iPhone.
