Commander Keen in Invasion of the Vorticons

Junk Food and Justice in Outer Space! A garbled transmission signaling the Vorticon's invasion of the third planet is the only clue. And wouldn't you know, it's after bedtime! For eight-year-old genius, Billy Blaze, the mission is clear. Pack a lunch, build an interstellar space fighter (from common household items) and protect the Earth. Become COMMANDER KEEN - guardian of truth, justice, and all the really cool "stuff" at the Mall!
