Zombietech

ZombieTech is a building located in downtown San Fierro. You can walk around in the main lobby area. There are quite a few pedestrians walking around in there as well. In the middle of the lobby there is a sculpture that looks like a strain of DNA. On a near by pillar there is a sign that says "Zombie Tech" and underneath it says "Sinister Zombie Viral Research Corporation Welcomes Visitors!" I believe it is suppose to be a take off of the Umbrella Corporation from Resident Evil. There are also elevators which I'm guessing takes you to the labs. You can't go anywhere but the lobby but I think it's an interesting place to see. Its one of the many mysteries in GTA San Andreas.

There is a camera over by one of the elevators that you can take.
