SWAT (315-5048)

SWAT is an abstract one or two player shoot-em-up in which the aim is to stop swarms of aliens from building a sectional tunnel from the bottom of the screen to the top.

At the top of each level are blue tunnel sections, while at the bottom are purple ones. Aliens start at the bottom of the screen in the purple sections. As they move through a tunnel, they can build new sections in any direction.
