Title                   : SPAM
Filename                : FOXHOLE.WAD
Authors                 : Ken Ahrens and Garrett Steele
Email Address           : eahrens@scruznet.com
Description             : OK, this is my first attempt at a Doom level,
                          so I went all out.  Spam is now the weapon of
                          choice, because it is so dangerous.  Everything
                          I can think of has been changed to SPAM, and I
                          included a level that I made with Garrett's help.
                          There is tons of edited sprites and a whole bunch
                          of other stuff.  Check it out.

                          a long time.  Sounds and music were cake.
