*Story*
Basically, a group of aliens that got stranded in an evil dimension
by humans wants their vengeance.  The Planet Praxis is attacked
and you have to save the Praxis human bases.  You are then sucked
into the evil dimension where you must get thruogh a gothic
fortress and find the portal to home.  At least you think
it's to home...

See my Vengeance page for the actual story.

I've been thinking of doing a Vengeance 2, for Doom2.  This was
my original plan for PSFDOOM.  It will take on the
theme of episode 4 of this one - Gothic/Midieval.
