Vikharev was one of the Red Army soldiers loyal to Captain Viktor Reznov, taken on the mission to capture Friedrich Steiner in 1945. He later followed his team to the abandoned ship. Reznov ordered Vikharev, along with Nevski, Belov and Petrenko, to follow him in. The group successfully reached the Nova Gas chamber, but Major General Dragovich, eager to see the effects of the weapon, ordered Reznov's six men to be placed in gas chambers and have the gas tested on them. Vikharev was placed with Petrenko and Belov in the first chamber, and died alongside them when the gas was released.
