Pyotr

Pyotr is a minor character in the Depot level in Metro: Last Light. He leads a caravan consisting of six resting stalkers waiting in the Depot.

Overview
When Artyom enters the Depot, he is confronted and held at gunpoint by two stalkers. Pyotr tells them to stand down when Artyom shows them his Ranger badge. Pyotr then provides Artyom with anything that he needs on his way.

Before he departs, Pyotr tells Artyom to let Miller know that "Pyotr said Hi"; Pyotr and his stalkers then leave the Depot, presumably on their way to Park Kultury down the Ring line.
