Spelunker II: Yūsha e no Chōsen (スペランカーII 勇者への挑戦, lit. "Spelunker II: Challenge to the Brave") is a Japan-exclusive action video game released for the Family Computer in 1987. An unofficial translation to English was made as a ROM hack.
Despite being titled as a sequel to Spelunker, Spelunker II: Yūsha e no Chōsen features vastly different gameplay. It is also not a port of the arcade game also called Spelunker II.
