ALIEN ATTACK (16K ZX81)
by J Jones, Cardiff
from Your Computer (July 1982), Pages 82-83

The object of Alien Attack is to try and shoot down the randomly moving
aliens without being invaded. You have three lives. The keys used are the
cursor keys to move left and right and the shift key to fire. If you shoot
all 128 aliens, another batch appears. The R key starts a new game.

If you wish to break in you will have to do so at the end of the game or
losing a life as this is the only time that the break key is operative.
