Zero Gunner 2 is a 3D multidirectional shooter developed by Psikyo as a sequel to Zero Gunner, the original arcade game. It was released for the Dreamcast in Japan in 2001. A version of this game was developed and released in 2018 for the Nintendo Switch, by Zerodiv. This version was given the title "Zero Gunner 2-" as Zerodiv had to rebuild the game almost from scratch, due to the original data being missing, and out of respect for both the original version of the game and purists. This version was later released for Microsoft Windows via Steam in December 2020.
