Delta Sector 5 - The Delta Complex is the most advanced
research facility on Mars. The complex is divided in the three main sectors,
each serving unique purposes and one smaller sector that houses the main portal.
Access can only be gained through the monorail or CPU Complex.
Betruger's voice come over the announcing system:
"You are too late! Hell no longer needs that portal to enter this world. The
invasion you saw was only the first wave. The Hell Gate it capable of sending
millions of my children into your world. Soon, the fleet from Earth will be
here, and with their ship, we will being this Hell to Earth!"
Your first mission is to the destroy the Hell Portal. It will turn out that
you'll need to do some other things first...
You're in the main portal room in Delta Labs 5. Straight ahead is 2 30 health
packs, a machine gun, 2 clips, a pistol and bullets. Pick them up. Don't bother
with the door; it is locked. Keep going straight, down the stairs, and you'll
notice a grate in the floor is missing. Jump down and follow the ducting. You'll
pick up a flashlight here as well. As you go, you'll notice some armor shards
and a pack of grenades in the duct. The grenades will come in handy in a minute.
Further on, there are also 2 clips off to the right. Since you lost all your
weapons and ammo coming back through the Hell Gate, pick up everything.
Finally you'll come to an opening in the ducting heading up into a passage.
You'll hear a chain gun-soldier coming from behind you and then pause. Arm the
grenades, and wait until he stops. Then stand up and throw 2 grenades fast, one
right after the other. Climb up and pick up the chain gun. Go backwards (from
where you heard him come from) and go through the door. You'll see a
whip-solider coming at you. Kill him, and keep going to the left. At the end
(its a dead end), pick up the chainsaw, the 50 armor, and the ammo belt. Go back
to where you came out of the duct, and keep going. Pick up the ammo elt near the
bay door, and then use the panel to the right of the door to open it.
Get the machine gun ready, because there will be a hallway off to your right
that twenty-eight spiders will come from 1-2 at a time. One way to handle it was
to stand back in the bay door area and shoot them as they come into the light,
but if you miss, they jump on you. Kill all the spiders and and proceed down the
hallway (don't go straight, it just dead ends at the bridge that was destroyed
in Delta Labs 4). Arm the soul cube (it will be ready, since it activates every
5 kills). A soldier will teleport in, kill him with the soul cube. It will also
fill up your life. No arm the chain gun and keep walking. A panel will fall open
to your right, but a soldier will spawn behind you. You can kill him with the
chain gun without taking any damage. Inside the panel is a plasma gun, 2 plasma
canisters, 2 clips, a 15 health pack and a pack of hand grenades. Keep going
down the hallway into the elevator shaft, turn right, and start climbing the
At the top, there is 50 armor on your left. Grab it, turn right, and duck into
the duct. Follow it until you hear the footsteps of the chain gun soldier. Look
down and you'll see him going down a set of steps. Toss a grenade down to soften
him up, jump down, and finish him with the plasma gun. Walk down the stairs. A
whip-soldier will come around the crates. Kill him , and grab the shotgun and 32
clips from outside the crates. Inside, there are 2 boxes of shells and another
clip. There is an arch-vile next, so arm your favorite arch-vile-killing weapon.
3 blasts from the shotgun at close range works well.
Proceed around the crates and through the warehouse. A bay door will open at the
end with an arch-vile. An easy way to kill him is to run up and shoot him three
times with the shotgun (don't forget to avoid his flame attack!) A whip-soldier
will now be running at you from behind, so spin around and kill him (duck to
avoid the tentacle attack). There is some plasma canisters and armor shards in
the bay where the arch-vile was. Proceed out of the bay, up the stairs (on the
right). Another arch-vile will show up from the door on the right at the end of
the catwalk. If you're hurting on health, you can use the soul cube, or save it
for the whip-soldier that will be coming form behind again. Kill both, and
proceed through the door.
Use the lift to go down to the first floor. Kill the chain gun-soldier that runs
up. Grab his chain gun and go through the door. You'll hear a revenant at the
top of the stairs. 2 shotgun blasts will kill him. There's nothing useful in
this room, so go up the stairs, turn left and go through the door. Again, there
is nothing useful here (even the Emergency Medical Station has 0 health in it),
so use the elevator to go up to Floor 2 - Delta Authority.
Exit the elevator, and go around behind it to the Delta Authority entrance. Go
through the door and you'll see Elliot Swann sitting on the floor, injured. Take
his PDA (you'll need the security clearance). He explains that he's injured, but
that Sarge is now be turned, and he doesn't know how long he's "been working
against us." He also explains that you've got to destroy the portal before the
fleet from Earth arrives. Your mission has changed: Use Swann's PDA to gain
access to the CPU Complex.
Go straight, pass the desk, and turn left and go through the door. You'll see an
open panel on the floor. Jump down, and go through the duct. Go all the way
until you see a ladder. Climb up, but there's no where to go. The duct you just
came out of had two levels, and you came from the lowest one. Jump back in and
follow the middle duct. When you can stand up again, you'll see a rack with 4
armor shards, 2 plasma canisters, 50 armor, 30 health and 2 boxes of shells.
Gear up and make sure all your weapons are reloaded. Turn around, and use the
panel to extend the service ladder which will take you down the the lobby you
last saw in Delta Labs 4.
Climb down the ladder into the lobby. An arch-vile will appear ahead of you down
the stairs. He'll spawn a whip-soldier to your left near the entrance to the CPU
Complex. As soon as you kill the arch-vile, another one will spawn to the right,
along with another whip-soldier. The sooner you kill the arch-viles the better,
since they can spawn monsters all day. There is 30 health and a clip to the
right of where you climbed down, and there is 50 armor hidden in the tentacle
area straight ahead down the stairs. When you're done fighting and grabbing
everything, go back up the stairs and use the panel to the right of the door to
get into the CPU Complex.
Inside, turn right, then left, then left again. There will be a revenant. Kill
him, and you can pick up the 30 health to your left, and the 50 armor and 2
clips to the right. If you need chain gun ammo, there is a hidden ammo belt if
you jump over the railing and walk along the service area at the end.
For some id software humor, turn right just before you go through the bay door
and download the "Pointers to remember when opening sacrificial portals". When
you're ready, open the bay door and Exit Delta Labs to move on to
