The Zombotech Corporation is a large commercial/industrial business entity headquartered in Downtown, San Fierro, San Andreas. Housed in a large square building in Downtown, this corporation owns one of the largest buildings in the city. The building features a glass foyer that is accessible and a huge sculpture shaped similarly to a DNA strand in the center of the building. Towards the rear are elevators that go to various zombie labs. The DNA strand is a snapshot, and a camera can be found nearby if the player doesn't already have one. The headquarters is also featured in the Jizzy mission as a hotel where Carl Johnson has to drop off one of Jizzy B.'s girls.
The Zombotech Corporation attempts to soften its sinistry, and inhuman corporate image by posting the following inscription on its lobby entrance: "Zombotech Sinister Zombie Virus Research Corporation Welcomes Visitors!".
