Use the Tunnel Glider, go downward, and enjoy the ride. Eventually, you'll reach a locked gate. Leave the Tunnel Glider and pull out the Laserkraftwerk to cut through the chain. Get back to the glider and continue on your way.
It's very easy to get lost in this section. So, pay close attention to these instructions. The path to the current objective is on the right, between the two sets of blades you had to adjust. Return to the Tunnel Glider and fly through the opening in the opening of the first blade set. The objective is on the right, so make a mental note of that. Fly through the gap of another set of blades, turn left, and go down another tunnel. You'll reach a large opening. Look to your right for a tunnel that's blocked by debris. Go toward the debris, exit the glider, and you'll find a Gold Snake at the base of the blockage. Get back into the Tunnel Glider and backtrack to the tunnel from earlier - the one we told you to make note of - to reach your objective. Leave the Tunnel Glider and climb up onto the ground. Move forward then climb the ladder on the left. Go into the next room and hold the lever until the area fills up with water. Now head back to the Tunnel Glider for one last ride.
You'll find the Tesla Laserkraftwerk Upgrade in this room. Make sure to grab it before continuing on. Use the Laserkraftwerk to cut your way out. Then turn right and keep your back pressed against the left wall. Keep moving ahead and you'll soon get two Signal Detect notifications. You'll want to complete the next section using stealth to save yourself some headache. When you reach the platform, you'll have the choice between climbing up or going underneath. Go up and wait for the guard to come near. Use your knife to take him out when his back is turned. Keep sticking to the left wall and use cover to reach closest Commander.
The Commander has a Kampfhund near him. Eliminate his pet first so you won't have to fight it later.
