take survivors to safety, but will leave soon. Vika, Natalie, and Anne go to other apartments to gather supplies. An alien senses them outside the Faraday cage and gives chase. When they get to the apartment, the alien gets inside with them. Sergei shoots the alien with his gun, to no avail. The alien kills him while the others escape. Anne is also killed in the ensuing chase. To fight back, Natalie sets the apartment on fire and meets up with Vika. The group later meets with Russian policemen who manage to wound an alien with conventional weapons. Sean collects a piece of the alien's body while the small police band agrees to help the group get to the submarine. As they move through the subway, an alien discovers them and kills Ben. The survivors make it to a powerless patrol boat on the river and drift downstream to the waiting submarine. The boat nears the submarine, but runs aground. As they attempt to push free, an alien light beam causes the boat to capsize. Sean and the policemen swim towards the submarine, but upon reaching it, they discover Natalie is missing. Sean is determined to get her, possibly missing his chance to escape. The policemen agree to help him. The submarine crew, after expressing their doubts about the rescue, assist by building another microwave gun with stronger batteries. Sean finds Natalie on a bus while the policemen and Vika start destroying aliens with the microwave guns. During the battle, Sean discovers the creatures' weakness when he throws a piece of the wounded alien he collected to another one, killing it. The two stop the bus and narrowly avoid a collision. After returning to the submarine, the police team decides to stay and fight for the city. Meanwhile Sean, Natalie, and Vika plan to spread what they learned about the aliens to the rest of the world.
