Ace of Aces

Note: some information is extracted from Electrosphere.info.

A piece of DLC for Ace Combat 6: Fires of Liberation, Ace of Aces (or AoA, hereafter) is a series of extremely difficult missions, spanning from The Invasion of Gracemeria to Heavy Command Cruiser. The missions feature an staggering deal of enemy presence in the battlezone, including the appearance of enemies never seen previously in some levels (for example, the raid of Gracemeria involves the direct participation of the P-1112 Aigaion, and Victor Voychek is now flying the CFA-44 Nosferatu.) Time your attack correctly & build a coalition to secure victory in this mission for the most hardened Ace Combat veterans.

Counter-Charge
A new addition to Ace Combat 6 is the arrival of the Counter-Charge System, which involves gaining Allied Support by destroying enemies during specific time segments.

Heavy Command Cruiser
The ultimate Ace Combat air battle, the mission begins with the appearance of a colossal Aegir fleet, filled to the brim with destroyers, frigates, aegir & battleships, including fleeing container ships, all of which contribute with a massive barrage of AA fire, and to make things worse, there is a shower of Nimbus missiles from the Aigaion. After the fleet is six feet under, the final battle commences with the appearance of the P-111X fleet. And if that wasn't enough, during the battle several of Ace's Combat's greatest aces will join the fray-- under Stovie colors. Blaze, Mobius 1, Gryphus One, Cipher remnants of the Yellow Squadron - that is to say, Jean-Louis, Gene & Yellow 13 and 4 -, and Estovakian aces Ilya Pasternak & Victor Voychek join the battle to make your like a living hell. That, and the CFA-44s' ADMM barrages (not to mention their UAV-45s) don't make the situation any better.
