The Underworld of Gamma-3

Mercenaries are on Maxim’s trail. They know about the secret activities of the mothballed laboratory complex “Gamma-3,” which Colonel Zimin had been so persistently searching for. But the mercenaries have no information about its exact location.

Maxim himself is affected by an experimental serum that the late professor Germanov administered to him. The young man is haunted by strange visions and hallucinations.

Maxim understands that the answers to the questions tormenting him are somewhere in the tunnels of “Gamma.” He needs to go down into the research complex again. How will “Astra” meet them after they stormed the hermogate and flooded the tunnels to escape? Who or what will stand in their way this time?
