The game - Xenon 2 - Sega Master System | SMS

You are given a space fighter under your responsibility, so that you can exterminate all other life forms that interfere with you. Note that the bosses here are not frail! Collect cash - then you can bargain with weapon sellers. Megablasters are the most powerful weapon. The game has 5 levels. The game was also released on Megadrive.

On your old ship, you got into the labyrinths of the planet XENON-2. The planet is inhabited by a wide variety of monsters. Everything that moves, flies and shoots, brings you death. When they collide with you, they die, but when they die, they take away much-needed energy. (borrowed from local site)
