Promise

Promise is a mission in Front Mission Evolved, following Providence. Leading up to this mission, Adela Seawell tells Dylan Ramsey that the E.D.G.E. System is not safe, and Ramsey orders it to be locked down. Just then, the dropship starts the approach to the Fort Ju Ku, the origin of the missiles that destroyed Uluru II.

During the mission, Godwin Mosley apologizes to Dylan into getting into this mess, claiming that he intended to keep Ramsey safe but only to be dragged into a potentially dangerous war.

Walkthrough
Note: The E.D.G.E. system isn't active in this mission.

Dropship shooter segment
On the first island, three wasp gunships, followed by a two missile turrets and two wanzers.

On approach to the mainland, there are two missile turrets high up, and a large number of wanzers approach from the left and right. They are easily destroyed.

Damaged dropship
In a cutscene, the dropship says the rear fuel line is damaged and needs repair. Here, you will disembark, and defend the dropship against approaching Wanzers. You will focus on attacks approaching from the right. If there's a notable gap in attacks, you may want to provide fire support to the other two teammates.

There are two major ground waves, followed by an osprey dropship.

After the dropship leaves, you can advance down the right path and continue. The first wall will have a few wanzers exiting a single hole, and engage.

Perimeter Outpost
There is plenty of ground forces in this area. Combat in this area comes to a close once the second osprey dropshop arrives. Head to the marker to continue. The door will be opened by an ally, and you will have a short trek outside with a few wasps.

Fort Ju Ku
There are a few wanzers present. They simply engage as normal.

After the combat, Cornelius Werner will arrive, and revive the downed Wanzers using a special feature of the E.D.G.E. System. The downed wanzers will be as strong a regular wanzers, despite having their armor visibly destroyed.

Once these wanzers are destroyed, Jed Gordon and Yun Tae Hwan will arrive and chase off Cornelius. The next mission, Fafnir, will begin.
