Spy vs. Spy II: The Island Caper

"The Island Caper" takes place on an exotic tropical island complete with a still-active volcano and other natural hazards. On the islands (in some levels there is more than one) buried in the sands are parts of the top secret X-14 1/2 missile which has crash landed there. Your mission is to find all 3 parts of the missile and assemble them in order for you to escape by submarine before the volcano erupts. (gamefaqs)
