The two switches are in the two Tunnel Systems, respectively. The Right Translation Wheel is in Tunnel System 1.

I didn't have problems with Tier 5.5* Ranged armor and two Aegisalt Pistols. That combination allowed me to kill any non-boss without running out of energy. (Aegisalt Pistols have the unique (?) property of firing a set distance regardless of how many enemies they hit, making them good against groups.) If you want to use lower tier armor, be prepared for more intense combat. Bandages and shields are always useful, as is Mulit-Jump or Pulse Jump. If you want the Right Translation Wheel, bring Spike Sphere, Ropes, a Grappling Hook (maybe two), or a friend.

*The 5.5 comes from the chestpiece being Tier 5 while the others were Tier 6.

Grab whatever Bananas, Bio Samples, Cocoa Pods, and Plant Fiber RNG (Random Number Generation) gives you as you make your way to the right. Lana Blake will talk to you, then press a button to let you through the hatch. Press the button you find on the left, then go right. The motion sensor will drop you through the hatch. (There isn't anything further to the right.)


The only available path is to the left. The doors only open from this side. There will be one guard in the next room. To get out, flip the switch and take the hatch down. The passage leads to a lever. Flip that lever to open the nearby doors. Continue to another lever. This opens the door on the right at the intersection.


This door leads to two things: a chest with random loot and the Right Translation Wheel. You'll have to come back later on in the mission to get that item.





Continue past the second lever to find a chest with Defensive Systems and the Miniknog Helmet. Also here is the first valve you need to turn to open up the path to the Right Translation Wheel.





After taking the right path and watching a hologram disappear, you'll reach this button. It opens the door above, and the one in front.

After passing the door, drop through the open hatch into this pool. Defeat the Miniknog who attacks you, then flip this lever. Run through the now open door to the right, then navigate the water to find a chest with Report on Rebel Bases and the Miniknog Chest. Come back up and take the door with the two motion sensors next to it.


After killing the guard, press the button. The next button is above you. While on your way to the lower button, you'll find a hatch. It leads to the Miniknog Greaves and Contents Page.





Kill the guard next to the lower door, then go up and to the left. A scientist will be guarding the switch to that door. Before passing through it, enter this room and activate the console. This is the time to run back and get the Right Translation Wheel. You'll need Spike Sphere, Ropes, or a Grappling Hook to get back to it. (If you have friends, I suggest leaving one behind to pick it up.)

Use whatever tools you used to get in to get back out.

After killing the one guard (located about where I'm standing), activate the valve and descend. The valve at the bottom does the same thing as the one at the top, just in case you jumped down and skipped the elevator. Take the elevator on the left. Kill the four Apex Mutants as you progress through the lab.


This switch opens the doors on both sides of the generator. The switch at the top of the generator turns off the barriers and the generator. If you descend the right side of the generator, you'll find a chest with a Visor. (If not, please report!)




Once through this door, you cannot return.








Activate the console. The two black areas below the hatches will spawn Mini Drones. You'll have to kill them as you wait for all the lights between the console and the TV to turn on. Then you can go the right and pass the checkpoint before exiting the tunnels.

Once you get above ground, you can go left to meet Lana Blake. She'll tell you that she's wounded. Twice I didn't find anything in any of the chests to the left. To the right, you can examine the paintings and grab whatever random loot is available. When you reach the room in this screenshot, get your weapons and boss-level healing in place. Then enter.

Big Ape has four weak parts: his projectors. Each has its own health, so you can take them out one at a time. His attack pattern consists of four main parts, in rotation:

• Shoot fists from the sides of the room and from the ceiling. Jump these.
  
• Shoot knifes from his eyes. Stand in a corner (without running underneath him) to avoid triggering the attack. Use this as an opportunity to attack the projectors.
  
• Rotate the projectors as he moves side to side. Stand in a corner to avoid this. (Which one may vary.)
  
• Fire two homing rockets per projector at you. Lure these into the ground or wall, then jump.

When you destroy a projector, the others recharge as Big Ape moves to the center and releases a plasma barrage. (It seems to be different each time.) Stand in a corner and pull out your shield right before they strike. The cycle will then start over, although the last projector will fire rockets instead.

The loot chest has the Miniknog R&D Report. Continue on to the Ministry of Knowledge to get the artifact and meet Lana again.
