Startropics 2 - Zoda's Revenge (USA)

About

The story begins with Mike Jones receiving a telepathic message from Mica, the princess of the Argonians whom Mike had rescued in the previous game. She tells Mike how to solve a cipher that he and his uncle, Dr. J, found on the side of the Argonians’ space pod. Mike goes to see Dr. J, and together, they solve the cipher and read it aloud. This causes Mike to be flung into the past. He arrives in the Stone Age. After helping a tribe of cave men retrieve their children from a flesh-eating wild boar, he finds an object, which Mica telepathically identifies as a Tetrad (or "Block" in the Virtual Console version). From here, Mike's journey sends him to different eras throughout Earth’s history to retrieve the rest of the Tetrads, such as Ancient Egypt, the Renaissance period, and the Middle Ages.
