The Horten's Nest is the sixth and final mission of Medal of Honor: Frontline.
Briefing[]
If you're receiving this, Patterson, then you are close to your final objective. Clearly we have underestimated this Sturmgeist fellow. I've been raising hell with intelligence as our info on him has been poor, to say the least. It is most worrisome. If there are others like him, our work just got a great deal more difficult.
We believe you're in the area of a top secret aircraft manufacturing plant. Operatives tell us it's hidden inside an abandoned mine. We haven't yet been able to pinpoint its location. This is where you come in. Locate and infiltrate the base by any means necessary. Upon achieving this, you must radio us with its exact coordinates. While in the complex, gather as much information as you can on the technologies the Nazis are developing. We are particularly interested in their new jet-propelled fighter called the 'HO-IX'. If this aircraft were to enter the war, there's a chance we could lose control of the skies. This would be very bad indeed.
So, to help prevent this, SHAEF is preparing to send a bomber group to drop heavy ordnance on the facility. You'll need to move fast and find your way out of there as soon as you've accomplished your mission. We'll await your transmission Jimmy, but if we don't hear from you by dawn, we'll have no choice but to assume the worst and go ahead with the assault using our best guess as to its location.
If past performance is any indication Jimmy, I expect to hear from you soon. Good luck, and godspeed.

Plot[]
The Horten's Nest is Lt. Patterson's last mission in Medal of Honor: Frontline. His main objective is to eliminate Hauptsturmführer Rudolf Ulbricht von Sturmgeist, and steal the Germans' new flying wing, the Horten HO-IX Fighter Bomber. Patterson brutally fights through countless German soldiers to reach the HO-IX's hangar, where he finally faces von Sturmgeist and his entourage of guards in a fierce firefight. Ultimately emerging as the victor (and the sole survivor), Patterson pilots the HO-IX and escapes the facility mere seconds before it is bombed to dust by the Allied forces.
Epilogue[]
Victory
Well done, Jimmy! I couldn't have expected half the results you achieved. So, take some much-needed R&R, but rest assured we'll be calling on you soon.
With Germany's battle for Russia going poorly on the Eastern Front and our success on the Western Front, Germany is getting less sure and more dangerous by the day. Hitler is turning to projects that we hoped would never see the light of day. You'll be part of our continuing efforts, Patterson, so rest for now - we'll be in touch.
Trivia[]
- It was revealed after the end of Stealing The Show that Patterson would be called back soon after the ordeal. This is a reference to Jimmy's attack on impenetrable Fort Schmerzen, which occurred on November 25, 1944, two months and a day after Stealing the Show.
- The bombers in this mission are actually C-47 transports.
- In Derailed!, Hargrove suggests that the bombing will commence in 1-2 days, but the mission takes place in 4 days.
- Hargrove's theory of the Allies losing control of the skies is highly unlikely. Like the Messerschmitt Me 262, the HO-IX was introduced pretty late in the war and would have been downed relatively quickly by the Allies' airforce and anti-air capabilities.
