Aliens Must Die is a real runner. The simplest ever controls are giving this game that additional charm. It may not be the typical masculine shooting game. You are a small boy with a water gun, but that gun is the only way to eliminate octopus like aliens before they kill you.
There is nothing about it, you may say after couple of seconds. Each next level will prove to be more difficult. Aliens Must Die is a sticky little game. Less than 5 minutes of playing this game and your concentration is back on the track. Try to find a game in this genre with the same level of excitement. The game costs nothing and that is just another aspect which makes it so unbelievable.
Free shooting games like this will not let you down once you start playing them. If not you, someone else will have hours of fun playing it.
