Xain'd Sleena

Xain'd Sleena (ザインドスリーナ) is an side-scrolling arcade videogame from 1986. The main character, Xain, is a galactic bounty-hunter or freedom fighter who must defeat evil forces who oppress five planets, each with different weather and geology, including forest, desert, and volcanoes, and a final metallic planet. Each planet is played with horizontal scroll, and after a final stage boss, the player plants a bomb (to the boss's shelter), jumps to a spaceship and plays an interlude stage during which he must break through enemy ships while heading to the next planet. After three planets there is a fight against a giant mothership.

The player can select the order in which he wants to play the various planets, so, there is no 'official' sequence of play.
