In this arcade classic for one to two players, collect pieces to assemble the ultimate weapon as you fight through waves of terrorists that have occupied the control center of a nuclear missile site.

## About This Game
The unthinkable has happened. Terrorists have seized the underground control
complex of a nuclear missile site. It’s up to you to infiltrate the
installation and eliminate the leader of the terrorist forces.

It won’t be easy, powerful tanks, treacherous waterways, and defended bridges
are all under enemy control now. The only weapon up to the task is called
Heavy Barrel, but it’s been dismantled inside the installation itself. Your
mission is to battle your way into the missile complex, secure and assemble
the Heavy Barrel weapon and use it to defeat the terrorists.
