Alien Disco Safari

In the fall of 1977, NASA launched Deep Probe Nine into space. In hopes of
making contact with extraterrestrial life forms, scientists crammed the
shuttle with cultural mementos, photos, and even disco records! Some years
later, Deep Probe Nine was picked up by an alien species who took an
unearthly liking to the disco records and now they've invaded Earth in
search of disco! Load up your weapons and stop them before it's too late.
