If you have been looking for a game that will offer you a lot of fun then you have come to the right one. Here in the game you have been given the responsibility of preventing the aliens from escaping the facility that they have been kept in. You must click on them to let them fall back. Remember that they will be flying in large numbers and randomly and so you should not only be quick but also be very efficient. The scores that you earn during the game play should urge you to do better.
