Siberia is the ninth mission in the game Conduit 2. It's where the player meets Katarina.

The Mission

Michael Ford enters the base in Siberia looking for Katarina. He battles his way through hordes of enemies before finding her strapped down in a containment chamber, dying.

Knowing Ford and Prometheus will do what they can to stop John Adams, Katarina succumbs to death and allows Ford to absorb her energy into the All-Seeing Eye. Ford then travels back outside where he escapes the base on a Free Drudge dropship.
