- After jumping into the teleporter on Xen, you appear in
a rubble-filled hallway next to an elevator. Hop in the elevator and go down.
- Upon leaving the elevator, make a right and continue
until you find a scientist in an underwater tank. Don't get caught off guard listening to
him, though - there are a few aliens behind the control panel waiting to attack. Take them
out, and then press the button on the control panel to transport the scientist back into
the lab.
- Lead the scientist back around the hallway and have him
open the first security door for you.
- There's a second security door after this, with a
bullsquid on the way next to three small water tanks. Don't bother with the second
security door, as the scientist will be electrocuted before he can get the door open. Kill
the bullsquid and climb up the ladder in the empty water tank.
- At the top of the ladder, you'll be attacked by a small
horde of aliens in the ceiling. After clearing them, more aliens will burst through a hole
in the wall at the far end. Make your way through the ceiling to a vent, climb in, and
drop down into the next lab room.
- In the middle of this room is a cage similar to the one
the scientist teleported in and out of. Walk in and press the button. The teleporter will
misfire a few times, sending chunks of debris into the water outside the room, and then
finally teleport you as well.
- Under water, find the nearby open vent. Climb in and up
and emerge in a darkly red lit room. Kill the zombies there and enter the small vent at
the end. At the end of the vent, drop down through a few grates into the water below. Find
the ladder underwater and climb onto the small dock.
- Continue inside until you make your way down to a small
crank. Turn the wheel and you'll see a grate in the water open, also freeing an
itchyosaurus. Retrace your steps and go back to the dock.
- Jump back in the water and go through the now-open
vent, paying proper attention to the underwater menace. Quickly make your way to the end
of the vent and close the airlock. The water will drain out, allowing you to breathe
again.
- When the other door in the airlock opens, you'll emerge
into a decontamination room. There's a button here to press, but it will only misfire and
explode. Enter the electrocuted hallway and shoot out the electrical box at the far end,
cutting the power.
- Head around the corner and through the decontamination
shower. A few aliens will appear, including one who, when killed, will provide you with a
new alien weapon.
- Continue into the airlock and press the button opening
the next door. Walk through the door, down the walkway and into the teleporter ball.
- You'll be teleported to Xen briefly, where you can make
a small jump and teleport back to yet another airlock. Press the button and open the door.
- The door at the other end of this hallway is locked,
but the walkway and glass beneath has been shattered. Climb through the hole in the glass
into the water, and swim up to the vent in the underwater ceiling. Break the grate open
and climb out into a small cave.
