Sapper is a resident of the apartment who was mutated by the hand creatures from the crashed bus in the Main Lobby. He has been caught up in the war zone of Mr. Henderson's mind, found in the green tent in the warped version of the Landlord's Apartment. He pays Sam $25 each to deliver Sapper Charges to specific locations and detonate them. He gives two initially, and will grant more if the player brings him Detonators and Explosives. Note: Currently, the requested detonators and explosives cannot be found in the apartment, leaving only the two charges for use. Sapper is not aggressive, but his mutation and the time warping in the apartment have caused his memory of his old life to become hard to access. He has spent subjective years on the battlefield here.
