Sapo Xulé: S.O.S. Lagoa Poluida is a retooled version of Astro Warrior, released by Tec Toy in 1996 for a Brazilian audience. It was later brought to Portugal.
S.O.S. Lagoa Poluida is virtually identical to Astro Warrior, but now takes place underwater rather than in Space. Astro Warrior had previously been released in Brazil making this the second outing of this game in that region - Portugal did not see Astro Warrior as a stand-alone release, instead in the form of the combo cartridge, Hang-On / Astro Warrior.
