The Fuehrerbunker ("Leader's bunker") is the setting of Mission 3: Ultimate Challenge, the second of the mission packs of Spear of Destiny. The Spear of Destiny has been taken from the United States by The Axe yet again and stored in Hitler's bunker. The bunker itself is located beneath the Chancellery in Berlin - it has been expanded and permanently sealed off, except for an elevator to the lowest level. The Nazis are using the Spear's power to peek into the future and gain knowledge of advanced weapons systems, which they try to develop throughout the complex.
