Definitely the most violent and dark of the series.
Several scenes feature large crowds of infected people (zombies) with disfigured and slimy faces, decaying flesh hanging from their bodies and teeth and eyes missing; open mouths release four talon-tipped tentacles that grab victims and pull them off screen; in one scene, the zombies are Russian soldiers firing handguns, automatic rifles, rocket launchers and machine guns on tanks; growling zombies chase humans and eat them, bloodying several heads, arms and legs amid screaming; and zombies growl and chase humans without capture and their mouths gush red blood, tentacles, claws and slime.
An extended fight scene is shown in reverse and slow motion and then forward at regular speed: Many large planes arrive at a barge and release special forces teams down long cables and they fire guns at a crew of men on the barge (we see bullets pass through them with a lot of blood spatter); two women each fire automatic guns at the special forces men and throw knives and slash men with swords amid splattering blood.
A team is killed by gunfire from one woman and later several other men die from a man's gunfire (we see no blood, but bodies fall).
An extended fight scene includes a woman dressed in a black cat suit, using guns and knives against an onslaught of zombies: she fights with multiple kicks, flying techniques, strikes, shooting people point-blank in the head and face (with a lot of blood), breaking necks and slamming zombies to the floor.
Several members of a strike team die at the hands of thugs and we see blood from gunshot wounds; one man suffers a seriously slashed face with open flesh showing, but he gets up three times, smokes a cigar, says he is having a good time and continues to shoot zombies and thugs before he dies.
A woman fights another woman and holds a knife to her throat, she throws the knife seemingly into the audience and a different camera angle shows it breaking a large TV monitor and the two women fight monsters together outside: the first two monsters are giant men whose heads are stuck with many rusty nails and they wield bloody axes and chop apart buses and cars until the two women blow them up by shooting into the gasoline discharged from a wrecked taxi; the third monster is a slimy, bumpy biped giant with an exposed brain and no matter how many times the women shoot it, it comes after them again in many scenes, smashing vehicles and buildings.
A strike team arrives at a corporation's headquarters where they set explosives allowing them to save a woman; they take an elevator and find special forces, zombies and spies to fight in several places and there is a lot of blood shed from automatic gunfire, explosives and zombies chewing on people's arms and sides while the strike team fights its way to the inner compound.
Two women fight their way out of a compound with a lot of shooting and bloodshed between zombies and spies and one of the women is shot in the side (we see a little blood).
Throughout the film, high-powered automatic firearms, rockets and machine guns of varying sizes are used in several corporate-owned holographic simulations of Suburbia, Moscow, Tokyo and NYC: We see cars, SUVs and buses explode in flames and smoke; car windows are broken, exploded and shot out; buildings explode in sheets of fire and smoke; people are shot with and without blood showing and driven against walls and snowdrifts by the impact and others are blown away by gunfire and are thrown over vehicles and smash to the ground, presumably dead.
A woman finds several control stations manned by men and women that have been shot dead, with blood dripping from head and chest.
Two men escape to the top of an elevator shaft with a woman and a younger girl to a place where a submarine breaks the ice and stops them; a fight ensues that includes three women and three men with one man dying immediately by gunshot (we see a little blood) and the others fight one another in series using punches, kung-fu chest strikes, takedowns and multiple flying kicks, as well as using guns, staves and tomahawks, and a man dies by a chest punch and a woman receives a chest punch but doesn't die.
Inside a warehouse (it looks like a slaughterhouse) we see clones of women and girls hanging on meat hooks as they travel along a spiral conveyor and a little girl sees them and cries.
A woman chases a monster into its lair after it has taken a little girl; she shoots the monster dead and finds the girl in an egg sac (she digs her out and the girl is unharmed).
A man in an egg sac falls out and we see him covered with slime and dead; a woman takes his explosives.
We see the body of a dead clone along the back of a couch, with her eyes staring at the ceiling.
Fires burn in front yards outside a house as cars crash around crowds of zombies when a woman, her young daughter and another woman take a car to the train station, but crash and flip end over end; we see one woman dangling upside down from her seatbelt but she is OK and they escape.
A brick wall surrounds the White House and outside we see a huge mass of millions of zombies, dozens of red vampire bats in the sky, giant slimy monsters with exposed brains and indistinct creatures all storming the walls.
A woman shoots holes in the ice under another woman who falls through and into the frozen waters.
A woman turns as she slips underwater and says, "I'm coming for you" to which the woman replies, "Good luck with that" as about 100 zombies pull the woman into the cold Bering Sea and chew on her, but we see no blood.
A woman and her young daughter see a zombie attack the girl's father and they scramble into a bathroom and then an attic while many zombies growl and pursue them; the mom kills a zombie with a ball bat and she and the girl run out of the house.
A woman gives herself an injection and we see her scratches and wounds heal, while bullets drop into the snow from out of her fingertips; another woman joins the strike team after their comrade pulls a mechanical mind-control beetle off her chest and shoots it until it stops skittering on the ice (we see it blown to pieces).
A man gives a large injection to a woman who writhes and groans; he tells her that she has new special powers now and that she will help save the world.
A woman in a helicopter receives three IV lines at once and appears to have no serious injuries.
Animated closeups show injected viruses entering human bodies and swirling around with many barbed parts causing people receiving the injections to grimace, groan and convulse.
Additional animations (X-rays) show teeth and jaws breaking in fights and hearts stopping when the chests are punched.
A graphic of a large city turns red as if soaked in blood and then a graphic of Earth turns red.
Automatic gunfire and men shouting accompanies the opening credits.
A woman awakens in a laboratory and appears bruised and scratched wearing only a towel (please see the Sex/Nudity category for more details); computer voices make her scream until she finds an armored cat suit, guns and knives.
A woman teaches another woman to shoot for self-defense.
Several times, a woman finds knives, guns and explosives to use to combat zombies.
A deaf little girl learns that her mother was a clone and cries.
One man in a small group of humans standing on the roof of the White House says, "This is the last stand of humanity. This is the beginning of the end" as the scene blacks out.
Explosions destroy an entire corporate complex.
Several men and women arrive at the White House to find it burning and smoking and the grass on the front lawn scorched and smoldering.
