From the back of the Box:
Date: Mark 8, 1945
Issued By: Army Intelligence, 9th Division
Briefing: Three allied saboteurs have been captured and are being held in the Eagle's Nest, the top secret Nazi fortress. Intelligence indicates troops massing in the area.
Orders: Penetrate the Eagle's nest. Rescue captives before they break. Destroy Eagle's Nest using hidden explosive caches. In process, save as many art treasures from destruction as possible. Good luck.
That's the job. Three fellow soldiers depend on you for their lives. Countless others may die if the fortress stands. A large cargo truck draws near. Seconds later you are under the canvas between boxes of ammo. You hear tires crunch on gravel then on stone and finally onto wooden planks. You just entered the Eagle's Nest...and you have just embarked on the challenge of your life."
