Archer Maclean's Super Dropzone

Very interesting arcade. Here we are in the role of astronaut, protect the planet from aliens. Cosmonaut our very mobile and flies pretty fast. Funny feature: if you fly long to the right or left, it turns out that the planet is round, and this gives additional tactical opportunities. The cosmonaut has a blaster, with which he destroys alien invaders. He can only shoot to the left or to the right. He also collects obscure, mine-like balls. For them you get points. At the end of the level there is a boss. Graphics in the game is good, the sound does not strain.
