Successfully complete Campaign mode on the Elite difficulty to unlock the Ace difficulty. In Ace mode, there is no health regeneration and enemies are stronger.

Complete the indicated task to unlock the corresponding aircraft.

Aircraft	How to unlock
F-15E Strike Eagle	Complete Campaign mode.
Mi-24 (HIND)	Complete Campaign mode.
PAK-FA	Complete Campaign mode under the Pilot or higher difficulty.

Keep initiating DFM as soon as possible on Marko during the following five sequences.

At the start of the battle.
A run over the Pentagon.
When he blows up your allies on two bridges.
When chasing him up past the Capitol building.
When he begins his run on the White House and you can see the Washington Monument in the distance. Note: This is where you can actually shoot him down.

You must initiate DFM as soon as possible because there is a secret timer, that when expires, will allow him to fire Trinity once. If you initiate DFM outside those five sequences, he will quickly perform a counter-maneuver on you.

An assault chain occurs when you destroy a hostile target in DFM and automatically go into DFM after another. To do this there must be another hostile close by as you kill the person you are currently targeting. It is easiest done in Blue On Blue mode.

Complete Campaign mode to unlock the PAK-FA. Then, go to Free Mission mode and sortie with the PAK-FA with Trinity (EW1) on any mission that allows multirole aircraft. Note: The "Siege" mission is recommended. Fire the Trinity at an enemy (for example, the two groups of enemies at the end of the "Siege" mission) to unlock the achievement.

Shoot down 50 players in Competitive Online mode.

Use an aircraft with 4AAM or 6AAM. When you activate DFM, go directly into afterburner. Be careful of the flames, especially under the Elite difficulty setting. Try to move to the right side of the missile. You will find an opening where you will not get damaged, but it will begin to close after the second missile. Try to pull away to the right when you start getting damaged. You will get missile lock in DFM, even when you are pulling away from it to dodge the missiles. About seven missiles are required before the mission ends.
