Niemi appears again at the bunker and engages in a fist-fight with Stone, while the radio room is overrun by zombies and Laakso and Kolya are forced to flee. As they near the exit to the surface, Kolya is grabbed by a zombie and falls to his death, with Laakso forced to leave him as he races topside to set the signal flares for the incoming fighter-bombers. Narrowly escaping the bombs, Laakso meets up with Stone again as they surrender to the incoming Russian battalion which has been called to investigate the site, knowing their job is done.
