Have you seen UFOs in person? Or have you heard about reports on discovering traces of UFOs? Do you believe aliens taking UFOs to attack the Earth? If that was true, what would you do? UFOs is a shooting game on www.flash-game.net where you fight with UFOs invading our lovely planet. Your mission is easy: shoot down those aggressive aircrafts when they fly across. But to finish the game perfectly is not that easy. Your enemies may appear from all the directions so you have to be very alert otherwise you may get shot and lose the game. Good luck!
