North American Research Facility

The North American Research Facility was an installation owned and operated by the Umbrella Corporation, located underground near Las Vegas. After the Global T-Virus Outbreak destroyed most of civilization, Umbrella survived by moving it's assets into underground facilities all over the planet.

History
After the T-Virus swept the globe, Dr. Sam Isaacs and the Umbrella Science Division relocated their operations to the North American Facility. Over the next five years, Isaacs worked on refining a way to domesticate the undead, using serums derived from the blood of the Alice Clones.

Following his infection by an Enhanced Zombie, Isaacs was executed by his second-in-command, Alexander Slater. However, he had already begun to mutate, and proceeded to massacre the entire facility staff before being contained in the lower levels of the complex by the controlling AI, the White Queen. Hours later, Isaacs was engaged in battle by Alice, before meeting his death in the re-created Laser Room.

Areas
Façade: The only above-ground component of the facility is an old weather monitoring station accessible via elevator, with a drainage ditch used to dumb dead clones, all of it surrounded by a chain-link fence.

Laboratory: The heart of the facility, containing the cloning tanks, storage ares for captured zombies, and equipment to synthesize chemical compounds.

Test Grid: The most notable feature of the facility was the area devoted to the testing of the clones. It consisted of several areas recreated exactly from Umbrella's facilities in Raccoon City such as:
 * Mansion Recreation
 * Laser Room Facimile
 * Raccoon City Hospital Replica
