Virus: "DC2" - weaponised mutagen. Symptoms: Mutates people into 'sickos' Planet Terror might be a darkly comedic, tongue-in-cheek movie that fondly homages the old grindhouse zombie films, but you wouldn't find many people laughing if the DC2 virus was released into the real world. The man-made virus turns people into horrifically deformed, semi-intelligent zombies that seem to exist only to kill people and spread the virus. Alarmingly, the only way to prevent the effects of DC2 is to either cut off an infected limb, or to ensure a constant intake of the virus to prevent the spread.
