Doom .WAD from alt.binaries.doom:
===================================
The level is so expansive you might
never find each other in deathmatch.
A nice mix of monsters,ammo,and first aid
in the level. If you think it is too
hard or too easy you may add or delete
ammo and health to suit your needs (I
don't mind). I have also hidden my
secret doors very well, and you may have
to use more of a "Wolfenstein" approach
to find them. Have fun!
