In the Space Frontier booth, you will come to the Invasion of the Space Raiders mini game. This is probably the hardest achievement to get. Once the level starts there will be a rocket to the bottom left. Shoot the rocket so it launches, making four green meteors appear in the bottom. Ring the four green meteors to make a large meteor come out from the left of the screen. About a second after the large meteor shows up, a UFO will come out from the left of the screen, right under the large meteor. Now the hard part, you will have to use the rocket on the bottom of the screen and have it both large meteor and the UFO. It is all about the timing.
