Master Takahashi's Adventure Island IV is the fourth and final Adventure Island game released for the Famicom. It bears the distinction of being the final official Family Computer game in Japan and was never officially released for the international market. Unlike previous entries in the Adventure Island series, Bōken Jima IV plays less like a linear platformer and more of an action/adventure platformer, similar to the later Wonder Boy games. Adventure Island 4 also has a unique password system that the earlier games in the series didn't have. It also features an egg item that allows you to teleport to the special spot where the player puts it. There is also a large variety of weapons to choose from which are unlocked by the player and can be used throughout the game. Many special items can be won in races and challenges, such as an angel/fairy item that allows the player to re-spawn at the spot where they died and a compass that acts like a map showing the player with an arrow where to go. The food system is completely new compared to the earlier Adventure Island games where you had a food meter and when it ran out the player lost a life. In Adventure Island 4, you don´t have an meter that slowly runs out, but instead you simply collect 8 food items to regain 1 health back.
