Welcome to the mathematical game termed Addition Aliens Attack, where if you enjoy math problems, spaceships and can think on your feet than you have stumbled upon the perfect game. In Addition Aliens Attack you are a lone space ship, constantly being assailed on by alien creatures that float down from the inky starry sky. To defeat these creatures it's your task to solve mathematical problems that are attached to these monsters by typing in the correct answer with your keyboard. If correct the ship will shot a laser effectively destroying the outlandish creature in the sky. If you get enough right you will be able to move onto the next level where the problems will get tougher and you will need to think faster in an effort to defeat all the monsters. Once you become a veteran of this game perhaps you will wish to try out the more demanding areas of game play. This is offered in the levels appropriately titled impossible or advanced, where the maths is even more problematical and the aliens more troublesome. So are you up for the challenge?
