Walkthrough - Polis | Chapter 5 Metro 2033 Guide, walkthrough

Walkthrough: This is going to be a very short level and you'll spend more time admiring the station than playing. Wait until the trolley has reached the Polis station #1. Start off by heading inside #2 where you'll have a chance to talk to captain Krasnov.

You should use this opportunity and purchase additional equipment from three of the local merchants #1 (they're selling guns, ammunition and a better armor). Exit this room #2 to be rewarded with the final set of cut-scenes.
