John Carmack has released an Open Source port of Wolfenstein 3D for the iPhone and iPod Touch.

What started off as looking at various iPone projects and then proof of concept ideas eventually led Carmack to take a look at the Wolfenstein 3D Redux project which inspired him to take it further.

The game was still fun to play after all these years, and I began to think that it might be worthwhile to actually make a product out of Wolfenstein on the iPhone, rather than just using it as a testbed, assuming the controls worked out as fun to play. The simple episodic nature of the game would make it easy to split up into a $0.99 version with just the first episode, a more expensive version with all sixty levels, and we could release Spear of Destiny if there was additional demand. I was getting a little ahead of myself without a fun-to-play demonstration of feasibility on the iPhone, but the idea of moving the entire line of classic Id titles over -- Wolf, Doom, Quake, Quake 2, and Quake Arena, was starting to sound like a real good idea.

Wolf3D is now available on the AppStore for a small fee and you can download the sourcecode for free here!.
