Peter is one of the guards of Exhibition.
Overview[]
Peter makes a very brief appearance at the beginning of the level "Chase", while Artyom is traveling on a rail-car between Exhibition and Riga. He informs Artyom and the rest of the caravan that the tunnel ahead has collapsed, and that they would have to take the service tunnel to Riga, which is a dangerous unguarded route in addition to being inhabited by ghosts.
