Source code for both PC and Dreamcast versions of Unsung. You will have to figure out how to compile the files by your self.
Unsung, a World War I adventure in Wolfenstein 3D, lets you slog through the trenches in true pixelated FPS fashion. Along the way as you fight through the German trenchs as an Allied Trench Raider in an attempt to disable a crucial German Artillery Bunker, you had better watch out for machine gun nests, flamethrowers, poison gas, and an army of soldiers out to kill you.
Based off Wolf4SDL code, Unsung is a stand alone mod which does not require dosbox to run on Vista or Windows 7. With new graphics, sounds, levels, and weapons, prepare for a whole new Wolfenstein 3D experience.
EDIT(1/17/2013): The source code has now been uploaded, you can find it in the downloads section.
Dead. That one word perfectly describes the current status of the Dreamcast port of Unsung. Now that the bad news has been dealt with, here is some good news. The incomplete and probably never to be completed port is now released and up for download. I had wanted to finish this awhile back but little work has been put into it the last eight months, and I don't foresee that changing anytime soon. As it currently stands the cutscenes still don't function and the frame rate is rather low. This port really can't be recommended but here it is.
Also if people are interested I'll upload the source code and people can have at it themselves.
