Half-Life: E7 Black Star

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. But thanks to the fact that the cascade resonator at Black Star was out of order, the planned incident didn't take place there. Object E7 is a laboratory complex researching anomalous materials and organisms. Its academic adviser is Dr.Victor Shmurghe. He has connected directly with G-Man.
