Wow!!! I would be able to do that if I could ever beat the Nosforatu on hard or expert mode so I could then get Ace of Aces mode unlocked. Just that one mission at the end is so annoying. Do you have any hints as to how I could do that?
Use the best and most strongest plane you have. Namely the CFA44 or the F22. Don't go for ops that have a shit load of anti air artillery. I had the most trouble with the Agaion, Pastermak and the Chandelier missions.
I went to Gamespot.com for detailed instructions on how to beat the game on Hard Expert and Ace. Just go to that site and type in the search box ACE COMBAT 6, locate the Xbox 360 version, click on it and scroll down to the FAQ list. It should tell you how easily beat each mission without getting killed as much.
