Ace Combat 8 Mission 27 Walkthrough

Quick route

  1. Attack useful structural targets and explosive facilities instead of treating every exterior icon as equally valuable.
  2. When the surrender and hold-fire orders arrive, stop shooting and read the changed objective.
  3. Line up the central entrance with room to adjust before committing to the interior approach.
  4. Attack the reactor as instructed and confirm the follow-up damage; do not assume the first hit completes the objective.

Mission 27, Fatsia, The Ocean Fortress, moves from attacks on the megafloat’s exterior to a central reactor objective. Structural targets help the opening battle; the later objective demands that you leave exterior cleanup behind.

Mission 27 Quick Route

Build your route around the objective transitions. In the opening, look for an attack that changes the structure you are fighting over. Later, stop thinking in terms of the targets you left behind and start thinking about the central approach. Continuing a successful opening pattern after the mission changes is a common way to waste a run that was otherwise going well.

The first practical decision is choosing a manageable exterior sector. Work through targets from a clear attack line and watch what collapses or disappears. That gives you feedback about which attacks are producing useful progress. Do not fly into the structure simply to inspect the result. Recover to open space, check the next marker, and establish the next line from there.

Objectives in Order

Fatsia is a megafloat installation with exterior defenses and structural targets. Support pillars and explosive facilities are useful to the opening destruction plan. The battle subsequently reaches surrender orders and a central reactor objective. Follow the current order rather than imposing a requirement to remove every remaining exterior target.

Use the following table as a transition checklist. It deliberately avoids a fixed score or time requirement: read the displayed objective for the difficulty you selected. The important distinction is whether you should still be attacking the exterior, holding fire, or lining up for the interior. Confirm that distinction whenever dialogue interrupts the action.

Aircraft and Special Weapon Choice

Start with a loadout that can handle dense surface targets while retaining control during the final approach. A surface weapon that reduces the number of exposed exterior passes can be useful, but the aircraft must still be comfortable to fly when the available space narrows. If you repeatedly collide inside, a familiar airframe is a sensible alternative to choosing only for destructive power.

Use the hangar to check weapon compatibility and your available reserve. Keep an air-capable option for threats that interrupt the surface attack. Do not commit every special weapon to targets already covered by an easy standard-missile pass. A balanced reserve gives you another answer when the approach you planned is blocked or when you need to recover from a missed attack.

For the reactor, favor a firing method you can line up and confirm. The size of an exterior target group is no reason to assume the same release pattern will work inside. Before entering, know which weapon is selected and which control changes that selection. Searching through options during a constrained turn is a preventable source of missed shots and collisions.

Mission Phase Walkthrough

  1. 1

    Create structural progress

    Choose a sector with a clear exit. Attack the relevant supports or explosive facilities, confirm the resulting destruction, and move along a planned line. Remove a defensive weapon when it prevents that line from being safe; do not turn every isolated gun into a separate low-level chase.

  2. 2

    Obey the change of orders

    When surrender or hold-fire instructions arrive, stop the attack immediately. Read the next objective and move into position for the central approach. An old target remaining on screen is not permission to ignore the new order. Allow enough distance to align before entering.

  3. 3

    Complete the reactor attack

    Inside, keep your attention on the marked reactor and the available firing window. An initial strike is followed by another attack before the shutter blocks the shot. Check the target feedback and mission confirmation, while keeping enough control to make the required turn rather than exploring side passages.

Handling Key Threats

Exterior defense and collision risk require different corrections. If gunfire disrupts every approach, clear the defense covering your chosen line or move to an angle with less exposure. If you hit the structure after a successful release, your recovery began too late. Give the next pass a defined exit and abandon the shot early if that exit disappears.

For the entrance, a longer setup is often easier to repeat than a last-second correction. Line up in open space, reduce the amount of bank needed at the opening, and keep the aircraft’s attitude readable. If the entrance drifts out of a safe line, reset before committing. Trying to rescue a bad entry from very close range can cost the entire attempt.

During the reactor sequence, distinguish a missed shot from incomplete damage. Check the selected target and visible feedback. If the first impact registers but the objective remains, prepare the follow-up rather than leaving to search for more exterior targets. Watch the shutter and current instructions; do not replace that information with an assumed number of seconds.

Troubleshooting a Failed Run

If you fail before reaching the interior, compare which exterior attacks created useful progress. Remove one unproductive detour and try the same sector again. If you reach the reactor reliably but fail there, retain the exterior route and practice the entry, target selection, and follow-up as one connected sequence. Changing the entire sortie at once makes it harder to tell what improved.

For rank replays, compare productive attacks, unnecessary exposure, and time spent reacquiring a target after each turn. Keep a successful clear as your reference instead of demanding a speculative numerical threshold. Mission 28 uses a different air-defense plan; continue to its dedicated guide rather than carrying Fatsia’s surface-attack loadout forward without review.

Common questions

Mission 27 FAQ

Do I have to destroy every exterior target on Fatsia?

Follow the active destruction objective and its progress display. When the mission changes to hold fire or the central objective, stop exterior cleanup and follow that instruction.

Why should I target supports and explosive facilities?

They can produce structural destruction, making them useful choices during the exterior battle. Check the result of the pass rather than assuming every red icon contributes equally to your route.

What should I do when surrender is announced?

Stop shooting when ordered and check the new objective. Releasing the trigger also prevents a planned cleanup volley from carrying through the change of orders.

Why did the reactor objective remain after my first hit?

The reactor sequence includes a follow-up attack. Check the target feedback and make the next required strike before the shutter obstructs it, rather than immediately returning outside.

How can I make the interior approach safer?

Align from open space, select the intended weapon beforehand, and reset a poor approach before entering. Use an aircraft you can control consistently through the entry and turn.
