Crossplay

Is Adventure Island II crossplay?

Crossplay does not apply to Adventure Island II: it has no online multiplayer.

Adventure Island II is a side-scrolling platform game developed by Now Production and published by Hudson Soft that was released for the Nintendo Entertainment System in 1991. It is the sequel to Adventure Island and the second game in the series for the NES. While the first game was an adaptation of Westone's Wonder Boy arcade game, Adventure Island II is an entirely original work, as were all the subsequent Adventure Island games.
