In the distant future, our civilization went to war against an aggressive alien race. In the game Orbital Invaders you will command the defense of one of the earthlings' colonies. You will have at your disposal a flying vehicle controlled from the surface of the planet, which is in orbit. Enemy ships will move towards the planet from the depths of space. Dexterously controlling your ship, you will have to take it to the target and, having caught the enemy in the sight, open fire to kill. By shooting accurately, you will shoot down enemy ships and get points for it. With these points, you can upgrade your ship and install new types of weapons on it.
