The associated zip file contains the graphics needed to change the Sargent character on Doom to an Imperial Stormtrooper from Starwars. Unzip to a subdirectory and then move strooper.bat to the doom directory. Then type strooper The file needs to change the original Doom.wad, so it firstly makes a backup of the old Sargent graphics. These graphics have been tested and have so far not caused any problems. However, I do not take any blame for any problems that my occur because of the use of these graphics. I am working on a more foolproof means of incorporating the graphics, and I will post this when I have tested it. For any queries please contact Philip, p.magnussen@auckland.ac.nz
