Essentials[edit]

Open the door in front of you. Run to the north of the next room, and hit the switch. Go through the tunnel with the armor bonuses, and hit the eastern switch. Run back to the north of the room, and go through the opening. Drop to the ground from the walkway, and run through the southern door. Open the next two doors to the west. Go around the curve, and open the eastern door. Press on the lift in the south, run in the alcove, and hit the switch. Take the lift up, and hit both switches in the newly-revealed closets. Head north, and through the eastern door. Run east until the walls open to the north, east, and south, and then grab the blue key in the east. Flip the switch behind it, enter the southern alcove, and go through the western opening. Take the northern lift, hit the switch, and quickly run to the southern lift. Take it up, hit the switch, and then dash over to the western lift. Ride it up, open the blue door, head north, and open the northern door again.

Jog to the blue door in the west, go up any of the rocky stairways, and head to the switch in the southeast. Hit it, go down the stairway, and enter the eastern tunnel. Take the teleporter, and then jump to the teleporter in the northeast. Go back in the teleporters you arrive in three times, and grab the yellow key in the next compartment. Enter the teleporter, and return to the western, blue door. Go up the stairway again, and open the yellow door. Go up the next staircase, run to the east, and flip the switch in the northwest compartment after it opens. Once the southern wall is lowered, enter the hallway, go up the next stairway, and open either of the doors. Flip the switch to the west to raise "steps" at the edge of the platforms in this area. Go into the teleporter and run southeast until the northeast wall lowers. Open the doors, go down the stairs, and trigger the western switch. Go back out, take the southeast teleporter, and open the southeast doors. Open the eastern door, take the lift down, and flip the eastern switch. Return to the outside, drop back down, and open the eastern, blue door.

Go across the bridge, open the door, and run to the switch in the east. Flip it, and run up the southern stairway. Open the door, head over the bridge, and flip the switch on the other side. Return to where you came from, and head up the stairs to the north. Flip the switch to lower the pillar. Grab the red key sitting on it, and leave through the next two doors to the west. Head through the red door at the north, and go under the skylight to open closets to the east and west. Hit the switch in the northwest compartment, go through the doorway, and go into either one of the northern corners in the next room. Hit the switch.

Secrets[edit]

  1. Open the wall behind the marine's corpse at the start of the map to find a backpack. (sector 38)
  2. After flipping the switch leading outside in the room with the creates, go into the closet with the medikit in it. Open the back wall to find a secret tunnel. (sector 60) Lower the lift to find a blur artifact.
  3. At the southwest of the level, before the curved passage, hit the switch to the north, and then the switch behind that one to lower walls in the north and south. Take the now revealed northern lift, and ride it all the way to the top. Turn to the east and open the wall to find a box of ammo, a box of shells, and a box of rockets. (sector 153)
  4. In the southwest, curved passageway, one of the northern walls at the southern side of the route is misaligned. Open it to find a switch. (sector 146)
  5. Flip the switch in secret #4, then run to the northern end of the hall to find combat armor (sector 148). This switch only works once.
  6. At the switch lowering the east end of the eastern bridge, open the opposite wall to find a switch. (sector 391) Flip it to open an alcove to the southeast containing four health bonuses, a medikit, a box of shells, and a light amplification visor.
  7. After lowering the east end of the eastern bridge, go back outside, and look inside the teleporter at the southeast platform to find that the back wall now has a completely different texture. Enter this teleporter, and then go in the teleporter to arrive on. After this, turn around, and run through the wall into another teleporter. You will be taken into a secret room in the northeast of the map with two stimpacks. (sector 429) Open the paneled wall in front of you to find a previously inaccessible soul sphere.
  8. After getting the red key, go back up the northern stairs, and enter the alcove there. Then dash as fast as you can back and up the southern stairs, through the southern door, and then west through a hidden door, before it closes. Take the lift (sector 472) up to the platform beyond, where you will find a plasma rifle and a bulk cell.
  9. From the end platform of secret #8, find a misaligned texture in the western wall. Press to open, and enter sector 473. In here, you will find a health bonus, a box of rockets, a bulk cell, and a computer map. Go down the stairway until you find a dead end; you can open it to get out.
  10. Within secret #9, enter the alcove to the north, and flip the switch. Exit the secret area (from the bottom of the stairs), then head south as far you can. The bars to the east there will have opened. Enter the cavern (sector 501). You will find seven health bonuses, as well as an invulnerability.
  11. From the entrance to secret #10 (just before the bars), enter the cavern, run to the silver teleporter, then through the nukage to another teleporter, just past the start of the west wall. If you can make it before that door closes, you will hit the secret exit (sector 509). This may only be possible by straferunning. The door opens and the timer starts at the threshold of the bars.
