St. Aubin medical facility

 (called Underground Lab ingame) is a location in Point Lookout found beneath the Point Lookout Lighthouse.

History
Before the Great War, the facility was used for research into improving the process of extracting and isolating brains, pioneered by General Atomics for their Robobrain robots. It was discovered that by manipulating the mixture for the biomedical gel it was possible to achieve effects previously thought impossible. Not only could the brain retain its full mental capacity under the right circumstances, but it could also project images and thoughts into other minds. This opened the door not only to applications in battle field technologies but also, for example, interrogation methods. The only concern was whether being isolated in biogel for years might have psychological effects.

Senator Calvert had his brother, Professor Calvert, transferred to the project not much later. Sometime later Professor Calvert had his brain extracted, this way allowing him to survive the Great War and receive psychic powers. Now, he operates the laboratory with his robots and dreams of entering the minds of as many people as possible. However, his goal is hindered by Desmond Lockheart, a ghoulified secret agent and his long-time nemesis.

The Underground Lab is the final location of the Point Lookout main quest. It is here the final confrontation with Professor Calvert takes place.

Layout
The underground facility is a more-or-less straightforward path from the entrance you arrive at with Desmond until the central antechamber where the actual brain of Professor Calvert is contained. The path winds ever downward, with side rooms and laboratories branching off from the central corridor. These rooms usually contain useful materials, particularly custom-built weapon components, Scrap Metal, and energy weapon ammo; energy cells in particular. Along the way, there are several locked doors which can be opened by key-cards of increasing security clearance.

However, these keys are in possession of the primary opponents in the facility: namely, General Atomic's Robobrain automated security. In addition to the robots, several Turret Robots activate at regular security checkpoints. A grenade explosion from a player with a moderate level in Explosives is usually enough to take out these turrets.

Notable loot

 * 71 Mesmetron Power Cells, not counting one unreachable pack (see the "Bugs" section).
 * Several Gatling Lasers, AER9 Laser Rifles, and AEP7 Laser Pistols
 * Microwave Emitter
 * 3 Pre-War Books

Bugs

 * In the circular chamber with Mesmetron Power Cells on the control desk (northern area of local map), one pack of mez power cells lies on the floor and cannot be interacted with/taken. The same goes for the two ammo boxes (containing energy cells and a Stealth Boy) right next to it.
 * Prior to that, in a supply closet just after the office with the sabotaged terminal, in a bucket behind the door there are three Microfusion Cells with which the PC cannot interact.
