## Description
A huge chain of cylinders are heading to Earth to conquer us from an advanced
and warlike alien race. Inside each cylinders are cities, fields, factories,
power stations and military bases, everything an invading force needs to
colonise another planet. Several attempts have been made to destroy this chain
but all have failed, until now. You are Earth’s last hope as you fly your
craft above the surface of the cylinders in attempt to stop them but Droidans
patrol the cylinders and will try to destroy you over eight levels. You are
armed with a gun and you can either blast or avoid the waves of Droidans but
if you are hit by one then you lose one of five lives.
Although advertised with the Commodore 64 version, this is just a vertical
shooter where the screen scrolls constantly upwards, instead of playing like a
Uridium clone. A joystick or keyboard can be used to control your craft.
