Military Junkyard
Back to Carrion
Head to the right and push the switch to open the hatch below.
Break the grates and take the only available path through the pipe to the right. This leads to the exit back to the hub but it’s not open yet. You’ll need to find the three save points first.
Pull the switch to open the door to the left and go through. Continue left to the first SAVE point. This opens up a tunnel to the left.
Head to the left and take out the human with a gun. Swim down the pipe and watch out for another 2 humans with guns. For now break the grate below and go down the pipe. You’ll find the second SAVE point.
Go to the left and you’ll find another Containment Unit. Use a tentacle to break it open and squeeze inside.
You find the Arachnoptysis ability that lets you shoot cobwebs to stun enemies or hit switches. Crawl up on the left and use the web to push the switch.
This opens the hatch below. Go up through the hatch and then up the pipe. You’ll be back in a previous room but this time you can use the web to hit the switch from the top right.
Go through the door you just opened and take out the humans in the next room. The only exit is through the breakable door to the right. Go right again and pull the switch. This opens the doorway to the exit and also the hatch in a previous room.
Head back to the left and down the hatch you just opened. This takes you to the third SAVE point. Spread biomass here to open the exit.
You can’t make any progress going down at the moment so instead head back to the right and up to the exit.
Frontier – Wastelands
Go through the pipe to the top left and go down. You’ll come to a cavern with an open door in the center.
When you enter a flashback will begin.
Flashback #1
You and your team arrive on the scene in a chopper and need to explore the facility.
Run to the left and climb down the ladders. Pull open the bit of grating under the closed door and it will open.
Head to the left and climb down. Plant C4 by the lower left wall.
The two others on your team will do the same. Run back to the right and pull the trigger to blow up the wall. Go through the hole in the wall to end the flashback.
Frontier – Wastelands
After the flashback the door to the top right will open. Go through and pull the switch. This opens the door back to the entrance.
Go down and to the right. Use the web to push the switch and open the door.
Go through and enter the tunnel to the next area.
