Invader is a thrilling sci-fi story about a crashed UFO and its reverse-engineered computer system that take over the minds of soldiers at an air force base. The alien entity, disguised as A.S.M.O.D.S. (Asmodeus), a strategic flight defense systems program for fighter jets, is discovered by tabloid reporter Frank McCall and D.O.D. Captain Harry Anders.
Together, they escape the base in a stolen F-19 and are taken to the Pentagon, where their story is met with understandable scepticism. However, an attempt by Asmodeus' minions to capture Frank & Harry for brainwashing convinces General Anheiser of their sincerity.
They return to the base and eventually face Asmodeus and its army of brainwashed soldiers in a thrilling showdown. Will they be able to defeat the alien entity and save humanity? Find out in Invader.
