Identifying him as a threat, they open fire, but as they investigate his corpse it is revealed the soldier is one of their own dead from the previous encounter, and as he springs to life a second time a number of zombies leap into action from their hiding places in the trees to further destroy the unit.

Forced to flee the battle to survive, Stone along with Finns Captain Niemi and Lieutenant Laakso as well as the cameraman's son take refuge in a trench, where they encounter lone Russian soldier Kolya, who seems aware of the zombie presence and leads them to a house where they can shelter.

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.
