Use the railcar to reach Venice - part 2 | Chapter 13: Bandits Metro: LL Guide
Last update: 11 May 2016
Instead of returning to your car, start exploring the next tunnel on foot. Pay attention to the two guards coming your way - first eliminate the bandit walking in front, and then, the one that has been lagging behind. In both cases, it is a good idea to make use of the side rooms and hide there in wait for the right moment to strike. After you have dealt with them, search through the corpses, and also look around the area for a filter and military-grade rounds.
Walk now a bit further to reach the fork. It is a good idea to explore the one to the left, for starters. Locate supplies after you reach the end of the tunnel. Be careful, though, while searching one of the corpses (the ones with its legs sticking out from behind the wall). This will lead to you being attacked by a mutant (the mini-game connected with rhythmical pressing of the correct key).
Return to the fork now and interact with the switch here. Only after you do that, return to your car. Reach the switch with your car and go into the tunnel to the right, i.e. the one with the corpse and the torches to the side.
