Richter is first seen when Task Force Vanguard is imprisoned at Berlin after captured by the Wehrmacht and is assigned by starts questioning with the commanding officer Arthur Kingsley, who is planning to manipulate the officer to escape once he's done with him. Richter then reports to his superior Freisinger, about "Project Phoenix" and the sixth man of the team (Novak, who is killed by Freisinger in the first mission) is dead, yet Freisinger doesn't buy it and orders Richter to get more information from the team
Richter then questions Polina Petrova, and tortured her, yet she tricks him to reporting to Freisinger, knowing that is something worth talking about. Richter calls the army to get the records from the Nazi commander Leo Steiner (who is killed by Polina) and to get confirmation of the sixth Ally is dead, Freisinger entered the office and showed a document of an American arrested at Tempelhof, for attempted to steal a plane. Freisinger is enraged at Richter for being tricked by the prisoners and made him to interrogate the "American" or he will get rid of him. Richter start questioning Wade Jackson, whom he thinks is the sixth man, but to no avail
Richter tells Kingsley that he lied, with the latter responding only knowing that he is dead, Richter then shoots and kills Richard Webb, Kingsley's sergeant to show what refusing him entails before leaving. As the officer is about enter to Freisinger's office, Richter overhears and sees several Nazi officers being taken away and executed, Freisinger informing him that Hitler killed himself, and Richter thinks that the war is lost. In the final act, Freisinger plans to get rid of Richter for being non-essential, but Richter then promises to get what he need in a short time with Freisinger giving him a final chance
Richter goes back to interrogate Polina, who reveals that Freisinger recruited Steiner for Project Phoenix; going to fetch Lucas Riggs and takes him to the interrogation room, not before finding a pile of corpses at there. After questioning Riggs, the paranoid Richter tells him it was never about winning the war, instead, for a coup, realizing Freisinger's plans to usurp Hitler to become the new Führer. When Wade's explosive goes off, Riggs captures Richter, revealing Kingsley's plan to have Lucas feign cooperation to escape from the Gestapo. When confronted by the team, Richter pleads with them, but Kingsley stabs him in the clavicle with Polina's knife to avenge Richard Webb. The team then leave their cells to stop Freisinger from escaping to Tempelhof, leaving Richter to bleed to death
