The object of the game is to defend your Mother Ship from attacking aliens. You have 3 squadrons, with three ships in each squadron. Aliens have six fleets of varying sizes. (Only three fleets appear at a time on the Radar Screen.) Destroy all alien fleets and you win! If your squadrons are destroyed first, the aliens move in and annihilate the hidden Mother Ship.
TIPS AND TRICKS
Dispatch your first squadron after the alien fleet CLOSEST to the Mother Ship. If possible, do not dispatch more than one squadron at a time, when playing with the Right Difficulty Switch in Hard position.
Try to hold one squadron in reserve, in case an alien fleet makes it to the inner rectangle. You can reach the threatening alien faster from the Mother Ship than from another position in space.
In Battle Mode, keep your gunsight moving. Alien photon blasts home in on your gunsight if it remains in one place for long.
As soon as you finish one battle with a squadron, send it back out afteranother alien fleet. Don't leave it sitting idle in space.
