This is a port based on Moritz "Ripper" Kroll's WOLF4SDL port for Wolfenstein 3D, a game developed 1992 by id Software and published by Apogee. The source code to the game has been released as GPL. The port implements a "bot" for this game, where the player is controlled by the computer, in the attempt to solve every level autonomously. Available as binaries for Windows and OS X, and as source package for Linux/UNIX (requires SDL and SDL_mixer to build). An experimental build has been released for 16-bit DOS and can be run with DOSBox.
