Storyline so far: Four years pass, and I have been once again transferred; this time to the Emmerian Air Force. I now have the ability to control many friendly forces whenever necessary. Two days after settling into the capitol's air force base, the shit hits the fan once again.

1. Invasion of Gracemeria

Storyline: The capitol is being invaded. Sent to deal with the situation and have been assigned a new wingman codenamed "Shamrock", who flies an advanced plane. Mission nearly completed, but multiple highly explosive missiles along with an ace group known as Strigon Team intervene with the mission and take down half the friendly forces. Ordered to retreat with remaining friendly forces to regroup for a later counterattack. Mission failed.

2. Heavy Command Cruiser

Storyline: The source of the ballistic missiles, now codenamed "Nimbus" missiles, has been identified as a super aircraft fleet. The fleet contains the heavy command cruiser "Aigaion", two Kotos-class radar ships, two Gyges-class aerial battleships, and half of the Strigon Team. Sent with Shamrock and other allies to attack the Aigaion head-on. The Aigaion, as with the rest of the fleet, has been successfully shot down, and the threat of Nimbus missiles has been removed.

3. Liberation of Gracemeria

Storyline: Before the mission Shamrock tells me all about his wife and daughter, and how much they mean to him. The mission to take back Gracemeria begins. The air base, naval and air superiority, and the capitol building have been successfully retaken. Strigon Leader Pasternak intervenes in his advanced plane, same model as Shamrock's. After a long aerial battle, Pasternak is shot down and killed. Gracemeria is free, and Shamrock goes to see if his family is ok.

4. Gracemeria Patrol

Storyline: Sent with Shamrock to patrol Gracemeria during the fireworks and celebration. Shamrock, however, has lost his family during the war and is severely depressed. A surprise attack suddenly occurs with many oversized shells dispersing into cruise missiles headed straight for Gracemeria. Ordered to intercept and destroy every single missile and enemy plane on sight. Analysis on cruise missile source is complete as mission succeeds. Shamrock decides to fly a bit longer.

5. The Chandelier

Storyline: Sent with Shamrock and every allied air force available to source of cruise missiles. A civilian contacts through radio transmission and provides vital information about the source obtained from a defected enemy soldier. The source is revealed to be the superweapon Chandelier, a colossal artillery cannon capable of firing a Stauros warhead, a single huge shell filled with cruise missiles, from thousands of miles away. The vital information provided by the civilian reveals the Chandelier's weak points, along with a hidden back-up cooling unit. The cooling units have then been destroyed, but the back-up cooling unit activates and the Chandelier evolves higher and becomes more accurate. Shamrock goes under to locate the back-up unit, succeeds and sends data to all allied forces, but is critically damaged and ultimately crashes into the water. Destroys the back-up cooling unit, but the Chandelier still stands and cools down by opening its barrel revealing its overheated core. Flies into the barrel, destroys the core and ultimately the Chandelier, and survives. Mission accomplished.
