Footage of animals (mostly deceased) being disembowelled as part of a funerary ritual.
We see a man removing his gas mask during a toxic chemical leak; an audio-recording of him later implies that he suffocated to death.
A young lab technician has his shoulder eaten on-screen as he screams in pain. High amounts of blood. Other background characters are seen being eaten at, having organs and tissue removed from their bodies.
We see a dead rat climb up a man's safety mask, chewing through his neck. Copious amounts of blood, including an implied popped artery as blood spurts across the mask's plastic shield.
A zombie kitten bursts from an elderly woman's crotch area.
Some graphic gross-out-type scenes, including maggots being picked from a corpse's eye socket and eaten, a man vomiting as another man regurgitates a rotten corn cob, a man urinating on a corpse, and a boy with an infected wound on his stomach.
We see a terrorist forced to surrender and drop his gun. Rather than arresting him, a man jumps out and slits his throat; large amount of blood, but the scene is quite brief.
Multiple scenes of zombies, including zombies violently attacking and killing. A little boy rips his father's heart out (offscreen) and eats it after becoming a zombie, in one of the more disturbing attacks.
