ACE COMBAT 8 Co Op Warfare is the main PvPvE mode in ACE COMBAT ONLINE. Two squads of four pilots compete for the highest total score while land, sea and air NPC units fight across the same battlefield. The Threat Level system raises the value of strong pilots as they stay alive and score, but it also makes them more valuable targets for the opposing team.
ACE COMBAT 8 Co Op Warfare sits inside a launch that combines a cinematic Strangereal campaign with a much larger online structure than the previous game. Bandai Namco has now detailed the Air Base hub, crossplay, separate online progression, two headline team modes and seasonal Ace Pass rewards. That makes the practical answer depend on the exact edition or mode involved, not just the game name. This guide focuses on the part a player actually needs to know before buying, unlocking or joining friends.
ACE COMBAT 8 Co Op Warfare: the PvPvE setup
Co-Op Warfare places two four player squads into one combat space alongside NPC forces. Unlike a pure deathmatch, success comes from scoring across the wider battle rather than only hunting the other team.

Co-Op Warfare is the more confrontational of the two headline online modes. ACE COMBAT 8 Co Op Warfare places two squads of four into the same battle while land, sea and air NPC units are also active. The winning side is the squad with the highest total score, so the battlefield has more useful targets than only the four human opponents.
NPC forces are part of the fight
Bandai Namco specifically lists allied land, sea and air NPC units. That creates targets and tactical pressure beyond the enemy squad and gives different aircraft roles more opportunities to contribute.
The PvPvE setup creates choices that do not exist in a normal team deathmatch. ACE COMBAT 8 Co Op Warfare can reward attacking valuable NPC objectives, protecting your own scoring run or intercepting an opposing ace at the right moment. A squad that focuses only on player kills can ignore a large part of the score economy around it.
Threat Level creates a risk reward loop
Earning points raises Threat Level and can increase score multipliers. A pilot with a high Threat Level becomes more valuable to opponents if shot down, so staying alive matters more as a successful run develops.
Online aircraft and equipment progression is independent from the campaign. ACE COMBAT 8 Co Op Warfare therefore uses the hangar you build as a mercenary pilot, not whatever you happened to unlock while playing the story. That separation lets the online mode tune its own progression without forcing campaign completion first.
Ace Aircraft can swing a match
Reaching three Threat Level stars gives the Ace Aircraft designation. Bandai Namco says encounters between Ace Aircraft can change the outcome of a match, because both pilots carry increased scoring value.
The Air Base gives teams somewhere to organise before entering Warfare. ACE COMBAT 8 Co Op Warfare groups can meet in the larger 100-player hub, form squads and prepare loadouts before an eight-player mission begins. The lobby capacity should not be mistaken for a 100-aircraft battle size.
Online progression is independent
Aircraft and mercenary progression in Co-Op Warfare belong to ACE COMBAT ONLINE rather than Campaign Mode. Even when the same aircraft appears in the story, it has to be acquired through the online reward structure for multiplayer use.
Crossplay is especially useful for a mode that needs two full teams. ACE COMBAT 8 Co Op Warfare can draw pilots from PS5, Xbox Series X and S, and Steam, making it easier for mixed-platform friend groups to build a four-person squad and for matchmaking to fill the opposing side.
Seasonal progression continues alongside it
Online sorties grant Ace Pass progress, giving regular matches a second reward track beyond mercenary rank and aircraft development. Premium Ace Pass adds more seasonal rewards but the basic Ace Pass is free.
Every online sortie also sits inside the wider mercenary and Ace Pass progression. ACE COMBAT 8 Co Op Warfare can move seasonal rewards forward while players improve rank and aircraft options. That gives repeated matches a longer-term purpose beyond the result of one battle.

ACE COMBAT 8 Co Op Warfare is easiest to understand once the official details are separated by edition, platform and mode. The launch package, online systems and rewards are all connected, but they do not use one shared entitlement or progression path.
