The robot in the Safe House
In the CIA Safe House under Mauer der Toten, at the end of the Maintenance Tunnel, a Requiem robot sits chained to a chair. The intel of the map tells why: sent to Berlin by the Director of Requiem, Klaus killed the three agents of the safe house. He is missing his hands and his battery.

Klaus in his chair
Deactivated, chained, his hands gone.
