Last update: 11 May 2016
Go through the door. Get to the console at the end of bridge and Use it (screen). A portal opens, through which you should go.
You'll be transferred nearby the first pylon. Exit cave and follow cliff until you meet first group of enemies (Crawler). After defeating them, move to the bridge, activate it, and move on.
After few steps, you'll be attacked again - but enemy will disappear after a while. When you get to area shown on the screen, you meet a group of enemies. Firstly, try to get rid of flying Watchers. They can throw away grenades, create shield and even resurrect allies.
When the area is clear, go behind a rock, behind which you find door. Get on the other side with corridor. You find ammo and weapon on the way. After going outside, you'll be attacked again. The sequence of elimination is the same: Watcher, Crawler, Knight. Area is big and allows flanking: use it.
Find a place shown on the screen on the other side of this area, but don't jump down. Stay on an elevation and kill enemies from there.
