You'll find yourself in a bay you left in, exit the bay, and take aright, and
find a door. In this room will be a rail to your left, ahead will be a dead
marine, collect his soul, and fight the Z-Sec, Once he has perished, two Vulgars
will spawn, Once you have cleared the area, head on up the stairs and through
the door ahead of you. Continue forward, you will find another dead marine with
a PDA next to him. Download it, and go through the double doors to your right.
There will be a tram ahead of you, ignore it, and take a left to find a
half-opened garage door. Head on under it.
In This room, there are many barrels scattered about the place, which could soon
become your best friend, or your biggest annoyance. If you are prone to
explosions, destroy the barrels before anything big happens. 3 Bruisers will now
spawn, activate your artifact, and punch em' out. After that, head up the stairs
and pathway that would be to your left if you were at the doors you entered in.
Head into the next room.
This next area is just a big straight-away, with a number of Z-Secs scattered
about the place. Kill them off, head forward and take on the Arch-Vile ahead of
you. Once he is gone, 3 revenants will pop out at your right and front, kill
them, head up the path to your right, and kill 2 more Vulgars that will spawn.
Head through the large door ahead of you, where a Bruiser will be welcoming you
on the other side. Kill him, head up the stairs ahead of you, killing many
enemies (mix of Z-Secs, Wraiths, Vulgars, Arch-Vile) along the way. Eventually
there will be a hall to your left, take it down the hall and go on through the
door at the end of it. Now You'll find a rather large room with a teleport in
the middle of the back wall behind plate glass, kill the Revenant to your left,
then head down the ramp to your right, which is hosting a Revenant at the
bottom, kill him and enter the large teleportation room. Activate your artifact,
and kill the bruiser, and 2 Revenants in the room, then head forward to the
control room ahead, have fun pushing buttons on this one! Select "Delta
Complex", and head back into the room, where it appears a Bruiser has spawned to
try and stop you, kill him, and head through the teleporter to
