The aliens have landed! And they've taken over our houses, buildings, and monuments. Well, if we can't have 'em, neither can they! Use your trusty rocket launcher to destroy the buildings they're squatting in. When they try and fly away in their UFOs, blow them out of the sky! There are five UFOs per level. Once you've completed all the levels, play again, but now your rocket launcher will have increased fire rate, and the UFOs will be faster. Quitting the game will reset your play-thru count. Use the trigger to fire rockets - hold it down for maximum fire rate. Use the menu button to reload a scene, quit the game, or switch handedness. HEALTH NOTICE: This game requires substantial head and neck movement, especially when playing seated.
