Reach Polis and report your findings about the Reds | Chapter 25: Depot Metro: LL Guide
Last update: 11 May 2016
Start by emerging from the metro tunnel. Go towards the depot buildings that you can see up in the distance. On your way there, you can of course, take a look into a few several optional locations; a small outpost, and the garages with the truck parked, to name the few (watch out for the tripwire!).
To push the story forward, go towards the building with the spotlight on; the one that the Dark One also stopped by. Explore several rooms to reach the door to a large hall, where there are several allies.
Start by taking off your mask, because you are not going to need it here. Go left and enter one of the railway cars. Inside, there are people you can barter with. The character shown in screenshot 1 deals in ammo, throwing knives, Claymores and grenades. The character shown in screenshot 2 deals in weapon modifications and new types of weaponry.
Leave the car and take the stairs to the catwalks above. Go towards the middle of the hall, which will result in the appearance of the hostile Reds. Stop atop one of the cars and wait until you receive and objectives update.
