The good guys have weapons such as garlic gas grenades, carbon bullets and knives, and guns with video cameras on the side. UV vampires don't register on cameras, video or audio equipment, in addition to not having reflections. However, alarms do go off when they push past an Underground ticket barrier, and they can use keyboards. Not to be confused with the Milla Jovovich Film Ultraviolet from 2006, which features vampire-like mutants.
