The Sprunk Factory is a factory that is located on Argus Street in Tudor, Alderney not too far from Honker's in Grand Theft Auto IV. Although the factory is accessible, it is abandoned and run-down on the 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 for threatening to inform The Commission that it was the The Pegorinos who stole the cocaine from the Russian Mafia.
- Dukes, can be found in the small parking lot next to the building.
- Two Contenders and a Super GT are parked there only during Trespass.
- There are abandoned train tracks that lead to an underground tunnel next to the factory. If you go under it, you will possibly find some tramps in the tunnel and a hole in the brick wall which leads to the interior of the building. Going ahead leads to a wall.
- If attacking someone/firing a weapon in the vicinity of the factory, a voice coming from nowhere will be heard. The voice actually comes from the bouncer of the Honker's located down the same street.
