Unfair E3M8

You will need Doom 1993 in order to play, and a source port like zdoom or gzdoom. The wad should work with most source ports. 

When the Unfair E3M8 file is installed, drag it into your source port file, so for example, I have zdoom, so I will drag it into the zdoom file, called zdoom.exe, but It'll appear as zdoom. Once that happens, click the original doom as a game option, and press New Game. Then select any episode, any difficulty, then once in a level, type in: IDCLEV38, and you will enter Unfair E3M8.
