The story takes place in Russia at the secret plant called "Object E7" or "Black Star" at the same time as the unexpected consequences at Black Mesa. G-Man was planning to organize three incidents of portal opening originally. First one - at Black Mesa Complex. Second one - at Black Star plant. The third place is unfortunately unknown.
