Ace Combat 8 Walkthrough: All 30 Missions and Boss Tips

Use this Ace Combat 8 walkthrough for all 30 missions, objective changes, boss phases, loadout planning, resupply timing, and post-game cleanup.

Quick answer: how to clear the campaign

The campaign is easiest when you follow the current objective instead of clearing every red marker. Watch the HUD, radio calls, countdowns, and friendly-unit reports. A bomber approaching a carrier, a missile in flight, or a ground unit that has stopped moving is usually more important than a fighter trying to pull you away.

The official ACE COMBAT 8 walkthrough page confirms the core loop: fast dogfights, aircraft upgrades, mission-specific superweapons, and squad commands. Use this page for the practical order of decisions, then return to the aircraft and combat guides when a loadout is the real blocker.

Campaign phase	What it teaches	Main risk
Missions 1-5	Interception, fleet defense, and ground support	Chasing fighters away from the protected target
Missions 6-10	Score thresholds, land battleships, and guidance lasers	Spending special weapons before the next phase
Missions 11-15	Weather, escorts, transports, and stealth movement	Losing the protected unit while tunnel-visioned
Missions 16-20	Identification, rockets, the Space Elevator, and image-recognition missiles	Firing before the mission permits it
Missions 21-25	Launch defense and split ground pushes	Staying on the wrong side of the battlefield
Missions 26-30	Fleet shifts, the Ocean Fortress, and the finale	Treating a multi-stage boss as one health bar

Missions 1-5: learn priority targeting

Mission	Focus	Reliable first-clear habit
1. Jokers Wild	Recon aircraft and escorts	Lock the reconnaissance targets before following escorts
2. Nomad	Carrier defense	Stay close enough to turn back toward bombers
3. Purple Magic Takes Flight	Radar-site defense	Remove bombers before ordinary fighters
4. The Fall of the Numbered Fleets	Two fleet groups	Clear anti-air threats, then move between ports
5. Retaking of Theve	Landing-force support	Kill the unit blocking the next ground advance

Mission 1 is a good control test. Practice target switching and missile range, but do not spend the whole sortie in a long chase. In Mission 2, the carrier is the timer: return to it when heavy attackers appear. Mission 3 rewards a bomber-first queue because the radar sites can fail while a fighter is baiting you into open sky.

Mission 4 has two fleet areas, so a balanced anti-surface option is more useful than a pure dogfight build. In Mission 5, read the movement of the landing force. The next blocker matters more than the total number of enemies left on the radar.

Missions 6-10: score, armor, and the Rainband

Mission	Main objective	What changes the route
6. Attack on the Drinwich Airfield	Support the advance	Avoid destroying the supplies the operation needs
7. A Lifeline in the Desert	Reach the required destruction score	A threshold is not the same as total destruction
8. Retaking of Theve II	Protect multiple friendly groups	Follow the group that has stopped advancing
9. The Land Battleship Blockade	Expose and destroy moving components	The vulnerable part changes several times
10. Over the Rainband	Find guidance aircraft through cloud cover	Follow the visible laser instead of searching randomly

Mission 6 starts with refueling and divides pressure between air and ground routes. Precision attacks are safer around objectives that must be captured intact. Mission 7 is a score problem; once the required number is reached, use nearby targets and save the return trip for a genuine ammunition problem.

Mission 9 is the first major lesson in state changes. A large target can remain visible while the real objective is a mobility system, containment section, or newly exposed weapon. Mission 10 is the same lesson in the sky: when the Tonitra guidance window opens, trace the laser back to the airship and destroy the source before the countdown expires.

The most useful resupply rule

Return to base when the next phase needs a weapon you no longer have, not simply because the runway is available. A landing costs time, but entering a boss phase with no appropriate special weapon can cost the entire sortie.

Missions 11-15: transports, defense, and escape

Mission	Threat	Practical response
11. Maximum Payload	Podarge transports in electronic warfare	Use contrails to reacquire one transport and finish it
12. Fort Grays defense	Cruise-missile pallets and airborne missiles	Intercept the missile immediately once it launches
13. The People of the Lost Century	A vulnerable resistance transport	Fly just ahead, clear the next threat, then return
14. Two on the Run	An unarmed escape aircraft	Stay low, use terrain, and limit unnecessary detours
15. Wings of Wax	Heavy bombers approaching the fleet	Put bombers ahead of fighters in the target queue

Mission 11 combines clouds, jamming, and large transports. Finding the aircraft is only step one; stay with the same target long enough to convert damage into a kill. Mission 12 reverses normal dogfight priorities: once a cruise missile is airborne, the fighter you were chasing can wait.

Mission 13 asks you to protect movement rather than chase the front line. Mission 14 is a route and visibility challenge because your aircraft cannot simply fight through detection. Mission 15 becomes safer when you attack exposed bomber components and leave the blast area rather than sitting behind a damaged heavy aircraft.

Missions 16-20: identify, launch, and intercept

Mission	Special rule	Clear condition
16. Singer	Civilian ships hide the real targets	Confirm the visual identifiers before firing
17. Land Battleship No. 3	Friendly bombers need a safe corridor	Clear air defenses before attacking the battleship
18. Moonlight and Shadows	Rockets are not valid targets immediately	Wait for launch, then intercept before the ceiling
19. Clearing the Lighthouse	A Space Elevator sits beside the fight	Avoid collateral damage while opening the route
20. Escort Orbiter	Image-recognition missile	Destroy the missile directly; flares do not solve it

Mission 16 punishes fast trigger fingers. Identification is part of the objective, so treat a suspicious ship as a confirmation task before it becomes a weapons task. Mission 17 is a bomber-support mission first and a battleship attack second.

Mission 18 includes a hold-fire moment. If the operation says the rockets must launch, shooting them early wastes the phase. Mission 19 adds collateral awareness around a major structure. Mission 20 contains a high-priority missile that must be destroyed by direct interception rather than by relying on countermeasures.

Missions 21-25: protect the launch and follow the push

Mission	Battlefield	Priority order
21. The Star-Bound Bird	Launch complex and shuttle	Stop whatever is moving toward the launch assets
22. Pursuing the HSCA	High-speed pursuit near Fatsia	Attack propulsion components, then withdraw
23. The Destruction of Expo City	Large urban battle	Clear the weapons pinning friendly units
24. Rocky Island, Day 1	Three beachheads	Shift to whichever landing group is under pressure
25. Rocky Island, Day 2	Eastern and western routes	Check both advances instead of committing permanently

Mission 21 is a countdown defense. Keep enough ammunition for later waves and use the air base only when the resupply cycle is worth the risk. Mission 22 is a pursuit, so lateral movement is safer than following one straight line into long-range defenses.

Missions 23-25 reward map awareness. In a large battle, friendly movement is a better compass than the density of red contacts. When a ground group reports that it cannot advance, remove the weapons immediately in front of it, then reassess the other route.

Missions 26-30: final operations and boss phases

Mission	Key idea	Common failure
26. Crossing Fleets	Respond to the fleet report	Clearing one corner while another group is exposed
27. Fatsia, the Ocean Fortress	Stop firing when the operation changes	Treating the exterior as the whole mission
28. A Thousand Points of Light	Preserve ammunition through repeated waves	Reaching the last formations with only guns
29. Selene	Break the guidance threat, not only the dogfight	Letting a difficult turn fight hide the laser objective
30. Song of Wings	Protect the Endurance through several phases	Searching for the submarine before it can be attacked

Mission 26 is a proximity trap. Use fleet calls and damage reports to choose the next sector. Mission 27 changes from structural damage to a hold-fire transition and then an interior fight, so stop attacking when the command changes.

Mission 28 is long enough for ammunition to become a strategy choice. Keep special weapons for bombers and heavy formations, then use a confirmed resupply window before the final waves. Mission 29 asks you to keep pressure on Selene while also watching the targeting threat.

Mission 30 is a sequence, not a single boss bar. Protect the Endurance from incoming missiles, follow the guidance phase, deal with the surfaced submarine's exposed weapons, and watch for the final underwater launch tube and ramming threat. If a target seems invulnerable, read the objective again before spending ammunition.

Loadouts, ranks, and post-game cleanup

The official game overview lists fighter, attacker, multirole, and electronic-warfare roles for online play, while the campaign uses the same basic principle: choose the aircraft and parts for the problem in front of you. A new aircraft is worthwhile when it solves a real limitation, not merely because it is newly unlocked.

Goal	Best first action	Avoid
First clear	Use a familiar aircraft with a balanced weapon set	Buying every new branch immediately
S rank	Replay after learning objective changes	Trying to perfect a mission while learning it
Aircraft collection	Track the aircraft tree and mission requirements	Farming currency without a target
Achievements	Use a checklist after the campaign	Replaying random missions
MRP farming	Choose a repeatable long sortie with resupply	Spending all special weapons early

After Mission 30, separate cleanup into categories: missing ranks, named-aircraft conditions, aircraft purchases, currency milestones, and online progression. Each goal needs a different replay plan. This prevents the common mistake of repeating a long mission without knowing what the run is meant to complete.
