Your aim in this very nice logical puzzle adventure game is to help you alien intruder to assimilate on the Earth. Just use YOUR MOUSE and find spots on the game screen you can click to advance in the game. Note, there are three possible endings in the last scene. If you like point and click adventures, horror and aliens. This should be up your alley. If you are stuck, you can use TAB KEY cheat. But DO NOT use it too often, it ruins the game. Enjoy!
