Master Takahashi's Adventure Island IV (高橋名人の冒険島IV, "Takahashi Meijin no Bōken Jima IV") is a 1994platform game released by Hudson Soft for the Family Computer; it was the final game released for the console in Japan. The game was never released outside of Japan.
Unlike previous entries in the Adventure Island series, Bōken Jima IV plays less like a linear platformer and more like an action/adventure platformer, similar to the later Wonder Boy games. Adventure Island IV
also has a unique password system that the earlier games in the series
did not have. It also features an egg item that allows the player
character to teleport to the pedestal where the player puts it. There is
a large variety of weapons to choose from which are unlocked by the
player throughout the game. Many special items can be won in races and
challenges, such as an angel/fairy item that allows the player character
to re-spawn once, at the spot where they lost all hearts and even a
compass that acts like a map showing the player with an arrow where to
go. Whereas in the earlier Adventure Island games the player character had a food meter and when it runs out, the player lost a life, in Adventure Island IV, the player simply collects 8 food items to regain 1 heart as health.
Eggplant Wizard kidnaps Master Higgins' dinosaur friends and later his
girlfriend Tina, Master Higgins starts an adventure to save them and
stop the evil eggplant once and for all.
