Jack Bros.

The portal between Earth and another mysterious dimension has opened, and the intrepid Jack Brothers have come through for an adventure in our world. Having lost track of time, they now have only one hour to return to their home or be banished forever. Help them battle hoards of loathsome enemies through six electrifying 3-D levels, each with many floors to explore and conquer. This is one phenomenal adventure you can't afford to miss!

The game is set on Halloween, where the narration explains that fairies take advantage of the special night to visit the real world. Unfortunately, the character has lost track of time and must now rush to make it back before midnight or face never being able to return again. The player is helped by a Pixie who explains elements of each level as they arrive and warns about approaching bosses. Each of the three initial playable characters have a unique ending sequence.
