Talchem California HQ
An abandoned compound, but might be frequented by Raiders and other, more deadly foes. It is an old factory/laboratory and watch out - it is a Full Loot Drop location! A good place for PvP. There is a working elevator that takes you from ground level to the 2nd floor, but you'll need some special key to get beyond the heavy doors.
"You found some keyhole, but you're not sure. Maybe it's for some special key?"
NOTE: The key stays in the terminal when you use it, and you can remove it when you leave.
WARNING! The interior spaces of this place are highly poisonous! You'll need to bring plenty of Antidotes.
