The game - Sapo Xule: S.O.S. Lagoa Poluida - Sega Master System | SMS

Vertical shooter. The plot is simple - we fight against the enemy fleet. Prizes in the form of ships change your ship for another, with more powerful weapons (you can’t change it for a weaker one). Also, you can pick up a couple of red helpers. If you manage to transfer to a ship with laser guns and find the aforementioned helpers, then all the bosses are taken out at once.

A hacked version of Astro Warrior. Tectoy released the game in 1995, replacing the main character, Sapo Xule, a famous TV Brazilian character.
