The Sprunk Factory is located on Argus Street in Tudor, Alderney. Although the factory is accessible, it is abandoned and run-down inside. Its first major role is in the mission Trespass, when Phil Bell takes Niko to the factory to take out Charles "Chubby Charlie" Matteo from threatening to rat out The Pegorinos to The Commission that it was them who stole the Cocaine from the Russians.
Contrary to myths, the abandoned Sprunk factory is not a haunted area. It was previously thought to be haunted, because you could hear a mysterious voice threatening you after discharging a weapon. In fact, the building is within a short distance of the Strip Club Honkers, and firing your weapon inside the factory will result in an unseen Strip Club Bouncer warning you to leave the area. Some strange things reportedly still happen in the Sprunk factory, including strange noises, lights turning on and off, and objects moving around the building. These strange happenings have made the abandoned sprunk factory one of the largest centers of attention for myth hunters in GTA IV. This is similar to the belief that the old hospital on Colony Island is haunted aswell.
- Dukes, can be found in the small parking lot, next to the building.
