This command can also be used to warp to the following 'secret' levels:
Finally, to access the modem-play level Faces of Death in single-play mode, start the game by typing DUKE3D/L7.
Episode 1 - Secret Level
The Secret Level in Episode 1 can be reached very near the end of Level 4 (Toxic Dump).
In the sewer, let yourself be swept along to the end - after having killed the Octabrains
- and catch your breath on the ledge where the auto-destruct is housed. Now, make sure that you
have some pipebombs and/or a loaded RPG and switch run mode on (by pressing Caps
Lock). Now you must travel against the flow of the sewage (nice image...) by jumping and running
until you reach one of the lit sections of tunnel. Close inspection of the right-hand wall will
reveal a crack - blow this to reveal the antechamber to the Launch Facility level.
Episode 1 - Boss
The boss at the end of Level 5 (The Abyss), can take some killing. However, there is
enough in this room (and the hexagonal room immediately prior to it) to allow you to waste him.
The key is to keep on the move to avoid his bombs and chaingun attacks. Make sure you pick up the
medi-kit and make it active - this way when your health dips dangerously low you can bump it up
quickly. Then just start doing circuits of the room, spinning round every now and again to let
loose your RPGs...when they run out, the boss should be sufficiently weakened and - as long as
your health is around 100ish - a chaingun battle to the death should see you emerge as victor.

Episode 1 - Hollywood Holocaust
This is probably the best level in Episode 1 for a one-on-one DukeMatch as it is relatively
small and most people know it pretty well. However, a few tips from Mystic Molly's Sad Owner
can help you come out on top...
The Holoduke Trick
This trap is made possible by the fact that in order to get their hands on a HoloDuke, your
opponent must 'play' the Duke Nukem game machine in the arcade...Get there first - with some
pipebombs. Don't play the machine: instead throw a pipebomb or two to the left of the machine.
Now go and hide somewhere secluded and nearby (through the door at the back of the arcade is a
good place and wait). Hopefully before too long, you should hear your opponent's character say
"Don't have time to play with myself" - detonate those pipebombs...
The Projectionist
The Projection Room is a very good location to make for if you've just
killed your opponent and the screen has been blown up. If this is the
case, the chaingun and jetpack will be sitting behind the screen,
presenting a big temptation for your recently-departed foe...From
your vantage point up here, you'll be in a prime position to see them
if they cross in front of the screen - even if you miss them going in,
they have to come out...
Invincible Hiding Place
The one 99% guaranteed best place to stand in this level is in the lift (the one to
the arcade). Assuming you have picked up the rpg, stand in here facing the foyer and wait
for either:
a) Your opponent to appear - in which case you blast them to bits
b)
The lift to start ascending. Slightly trickier here; you should run out the lift and turn round,
waiting for the lift to descend again, hopefully with your blissfully unaware opponent in it...
