You're in command of the Starship Enterprise, protecting Starbases from a relentless attack by hordes of Klingon ships. Put your shields up charge phasers and photon torpedoes and ready warp engines! The deadly Klingons can knock out your defences, weapons and engines with phaser fire or by colliding with your ship. You'll need skill and lightning quick strategy to stay alive and retaliate. If the Enterprise is damaged, dock at a Starbase to replenish supplies. Watch out for NOMAD, who releases explosive mines! Hit NOMAD with you phaser before it's too late. The battle rages on more fiercely through sector after sector of Federation space!
