Darius Gaiden (Japanese:ダライアス 外伝, "Darius Side Story") is a shoot 'em up video game released for the Arcades in 1994 in Japan and North America, respectively. Arcade promos in North America announced it as Darius III, but never got released with such name. The "extra" ROM hack version was released in 1995. The ROM hack version features rearranged levels, as well as automatically-enabled auto fire, two extra weapon power levels (bigger wave shot and a bigger red wave shot) and an all-stage mode that can be accessed by starting the game in two player mode.
