This is a complicated take-off of one of the oldest arcade games,
Space Invaders. The lower section of the screen remains the
same, but the marching intruders have been scrapped to be
replaced by funny blue things (cronies). The mothership has
stayed, but there are now three alien captives in the middle of the
screen, surrounded by a tough red wall.
It is your job as the Autoguard to stop the cronies dismantling
the wall and so rescuing your prisoners.
You can lose one of your three lives by being hit by one of the
bombs dropped from above, or if a prisoner is freed by a crony.
The normal left, right and fire controls are used, and as soon as
you have blasted all the cronies from one screen you immediately
move to the next. From the third screen onwards you are often.
confronted with a menacing creature called the bug. He must be hit
in a specific place and is worth 10 times more points than the
cronies.
A definite must for all "shoot 'em out of the sky" fans.
