Wars on Earth can be scary, merciless and brutal, but they are no match for those that await you in space in UFO Attack. While the earthlings were at war with each other, inventing new types of weapons, an army of aliens from outer space approached the earth's orbit and they obviously have bad intentions. Alien aggressors only want our resources. They will gut the planet, destroy all life and leave. To avoid this, you have to fight. Your ship is one of the few that will repel attacks in its area, trying not to miss a single enemy starship to Earth in UFO Attack.
