When the game was released on the Playstation, it was packaged alongside the Playstation port of the original Strider.

However, in the North American release, the games were printed to the wrong discs. Strider 2 was printed to disc 2 (labelled "Strider"), and Strider was printed to disc 1 (labelled "Strider 2"). This affects all North American copies of the game.
