Use the signal bell to call for a ferry | Chapter 13: Bandits Metro: LL Guide
Last update: 11 May 2016
As you can probably figure out, calling for a ferry will involve putting up another fight. You cannot really get prepared for what's coming but still, you should acquaint yourself with the chamber's structure, and remember the whereabouts of supplies (at the corpse on the upper level, there is a double-barreled shotgun). Once you decide you are ready, interact with the cord shown in the above screenshot.
After a few moments, there will be mutants appearing in the area. I recommend that you utilize the strategy of attacking the monsters at a distance first (screenshot 1), and finish off the ones that made it closer with a shotgun or a different weapon effective at close quarters (screenshot 2). Try to remain in motion at all times , and do not let yourself be cornered. Make use of medicines if Artyom sustains heavy damage.
You need to keep fighting the monsters off until the ferryman lets you know that he has arrived. Do not continue to fight the mutants then, return quickly to the water reservoir and embark on the ferry.
The last part of this chapter is not too demanding. Keep firing at the monsters that chase the ferry - this shouldn't be too much of a problem. Soon, the loading of the next level will start.
