gk is a construction group. Im not really sure about what GK means but i know that Nova also means blast. I think a possible thing it means is Reconstructing the blast V6. It said a Nova is a cataclysmic nuclear explosion. maybe back in an alternate past that Treyarch made up the U.S. nuked Russia during the cold war and they are reconstructing and the zombies are just from fallout. :|when i typed in Geistes Kontrolle in google translate from german to russian Mind Control came up. The weird the was i wasnt translating to english. HWen i translated to Vietnamese this came up."Kiểm soát tâm trí" mind control still.(duh)마인드 컨트롤
