Starship War P.I.G.s

From the publisher's web site... "Vicious, gigantic bugs want our candy bars and they're willing to invade Earth to get them! The arsenal of the entire planet has turned out to repel them... too bad it's the 1950s and that arsenal doesn't amount to much. Starship War PIGs pits plastic Bugs against plastic Infantry Guys in a titanic miniatures struggle for the mastery of Earth. "
