You control Pitfall Harry as he makes his way through an underground Peruvian cave in search of the valuable Raj diamond, as well as his lost niece and cat. Once all three have been found, the game is over. The gameplay is fundamentally the same as Pitfall!, but with a few new twists. The environments are no longer limited to a horizontal plane, so navigating through the complex maze of corridors becomes a matter of puzzle solving and timing. Harry has also gained the abilities to swim and float across chasms using a balloon. The scorpions make a return appearance, but there are many new creatures for Harry to avoid, such as frogs, bats, electric eels, and condors.
