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.
