STORY:

Duke Nukem gets captured by friendly monsters that own a huge satelite.  They 
bring him to a huge prison orbiting earth.  They plan to execute him without a 
trial.  What has gotten into them?  They throw him in jail and he has to 
escape soon or else he has a choice of execution in three days: Get crushed by 
a ceiling, melt in radioactive waste, or get blown into and airlock!  But he 
grabs a gun hidden under his bed and is ready to kick butt and find out why 
the leader of the prison turned against humans!  To finish the level, you need 
to destroy two boss spawns, and finally reach the big one at the end! (Level 2 
under construction) 

=====================================================================

The level includes:
SECURITY CAMERAS, A SUBWAY, A SPACESHIP, A COURT, JAIL CELLS, A STAFF 
HEADQUARTERS, AND MORE!!

=====================================================================

How to play:
                    
Just make a backup of user.con and overwrite the old one with my user.con
Then, (MAKE SURE THAT PRISON1.MAP AND PRISON1.BAT ARE IN 
DUKE NUKEM'S DIRECTORY!) type prison1 and enter a choice.

HAVE FUN!!

At the end, a hint is provided for the combination if you look closely at the
walls... When the door opens, go through the elevator vent to get rewarded.
In the room where the boss is supposed to be, examine everything, don't shoot
the lady in the pod or else a commander will appear.  To find the boss, examine
the two heads on his chair...
