Fantasy Zone II: The Tears of Opa-Opa

Fantasy Zone II: The Tears of Opa-Opa (ファンタジーゾーンII オパオパの涙) is a Sega Master System game created by Sega in 1987. Like in the first Fantasy Zone, the player controls a sentient spaceship named Opa-opa who fights surreal invader enemies. Like its predecessor, Fantasy Zone II departs from the traditional scrolling shooter themes with its bright colors and whimsical designs. For this reason, it is occasionally dubbed a "cute 'em up".
