Astro Warrior (アストロウォリアー Asutoro Uoriā) is a shoot 'em up video game developed and manufactured by Sega for the Master System in 1986. Set in space, the player flies a spaceship shooting enemies and collecting power-ups to reach the mother ship of an invasion force. Reception was mixed, with critics criticising the generic nature and lack of variety, and others praising the graphics. The game was re-released on the Hang-On / Astro Warrior compilation in North America, and the Astro Warrior / Pit Pot compilation in Europe. In 1996, Tec Toy re-released the game in Brazil as Sapo Xulé: SOS Lagoa Poluída, and based it on a Brazilian 1980s toy. This version was also released in Portugal.
