Biohazard

The story revolves around scientists conducting experiments on transferring matter from other dimensions in a remote desert research laboratory. However, things go awry when a container holding a creature from another dimension is opened, releasing a series of monsters that start rampaging and killing people.
The protagonist of the film is Mitchell Carter, an army officer tasked with tracking down and dealing with the monsters. He teams up with Lisa Martyn, a psychic who has been involved in the experiments conducted by Dr. Williams. As the story progresses, it is revealed that one of the leading characters is actually one of the monsters, adding a twist to the plot.
The midget alien creature (Christopher Ray, the director's eight-year-old son) is depicted as a black, reptile-like being with large beetle shells attached to it. It goes on a killing spree, even attacking a poster of the iconic character E.T. from the film of the same name. Additionally, a snake-like creature is mentioned that emerges from the container, but is eventually killed by Carter.
