This pack includes the arcade original (and its Japanese variant), the sequel Twin Cobra (as well as Kyukyoku Tiger, the Japanese equivalent), Sky Shark (alongside the Flying Shark and Hishou Zame regional versions), Fire Shark / Same! Same! Same! and Twin Hawk / Daisenpuu. That’s five different coin-op classics, split across eleven different variations. There are also notable differences between these variants, too; for example, the international version of Twin Cobra allows you to respawn in the same spot when you die, while the Japanese version, Kyukyoku Tiger, requires you to restart from the nearest checkpoint.
