ACE COMBAT 8 Co Op Assault is an eight-player PvE score competition in ACE COMBAT ONLINE. Two teams of four tackle enemy forces and mission objectives while competing to finish with the higher score, so the mode combines cooperation inside each squad with a score race against the other team rather than direct player-versus-player combat.
ACE COMBAT 8 Co Op Assault 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 Assault: the basic format
Bandai Namco describes Co-Op Assault as player versus enemy combat split across two teams of four. Both squads fight mission targets, but they are also competing for the highest total score rather than simply sharing one combined objective.

Co-Op Assault is a PvE score competition rather than a direct player-versus-player dogfight. ACE COMBAT 8 Co Op Assault puts two teams of four into missions with enemy forces and objectives, then compares the score each squad produces. That creates pressure from another team without requiring pilots to spend the whole sortie hunting human opponents.
Why team composition matters
Online aircraft include Fighters, Attackers, Multirole and Electronic Warfare roles. Bandai Namco specifically notes that different aircraft are suited to different battlefield jobs, so a balanced squad can cover air threats, ground targets and support needs.
The score structure makes target selection important. ACE COMBAT 8 Co Op Assault rewards a squad for clearing objectives efficiently, so a team that coordinates aircraft roles can outperform a group that simply chases whatever target appears first. The mode should suit players who enjoy cooperation but still want a competitive result screen.
Threat Level changes scoring risk
Players build Threat Level by earning points. A higher Threat Level can increase the score earned from destroying targets, but it also makes the player worth more points if shot down. Reaching three stars marks an aircraft as an Ace Aircraft.
Aircraft expansion is tied to progress in the online mode. ACE COMBAT 8 Co Op Assault can therefore become different as a mercenary account develops, because the player gains access to more aircraft and equipment choices over time. That progression belongs to ACE COMBAT ONLINE and remains separate from the campaign save.
Aircraft progress through sorties
Aircraft gain levels as they survive missions, improving stats and unlocking abilities. Mercenary rank also opens access to more aircraft, creating a progression loop that sits outside the single player campaign.
The Air Base is the preparation space before these sorties. ACE COMBAT 8 Co Op Assault players can use the hub to meet pilots, form squads, customise their mercenary avatar and work on their aircraft setup before launching. The base can hold up to 100 players even though an Assault mission itself uses two four-player teams.
What can happen after a mission
Returning from Co-Op Assault can trigger limited time activities such as Scramble or Emergency Sortie. Those missions change the normal structure by sending pilots after powerful rival squads or large iconic weapons.
Crossplay widens the available squad pool across PS5, Xbox Series X and S, and Steam. ACE COMBAT 8 Co Op Assault is therefore not restricted to four friends on identical hardware. Mixed-platform groups can still coordinate a full squad once everyone has online access and the game entitlement on their own account.
How rewards connect to Ace Pass
Playing online contributes to Ace Pass progression. The free track awards seasonal items as players gain Ace Pass XP, while Premium tiers add extra rewards and can include playable aircraft.
Sorties also feed the Ace Pass, which gives the mode value beyond one scoreboard. ACE COMBAT 8 Co Op Assault players can progress seasonal rewards while building online rank and aircraft options. The free pass exists for all online players, while the Premium tiers add extra rewards rather than replacing the core mode.

ACE COMBAT 8 Co Op Assault 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.
