Zombotech is a mysterious company, working as a virus research corporation, operating from San Fierro. Zombotech has been a subject of many Zombie myths, largely theorized to clone zombies in San Andreas. According to a investigation by an infamous youtube myth hunter, ulown00b Jizzy B, and his business is very well integrated with the Zombotech. The player claims that the money earned by Jizzy B is said to be invested in cloning zombies, this operation is headed by Zombotech and assisted by the Bio-Engineering works in Montgomery. Zombotech's connection with the Biowell could be very well plausible and has been theorized by myth hunters for over a decade but the involvement of Jizzy B is highly unlikely.
The myth as explained vaguely by the myth hunter who at a point stops explaining the myth, claiming it to be too complicated to understand, has no authentic base, making it a false myth.
