Ace Combat Online
Choose co-op or PvP, understand progression and threat stars, and prepare for limited-time superweapon encounters.
Find the right starting point.
Start by separating a mode choice, an upgrade gate and a connection failure. Regular cooperative enemy combat, direct player competition and special superweapon sorties solve different goals. The guides keep online ownership separate from campaign progress.
- Want PvE with a friend? Compare Assault and Warfare first.
- Aircraft feels underdeveloped? Check levels, cap upgrades and slots before replacing it.
- Chandelier offered? Read the chamber and cooling sequence before the timer starts.
Co-op, PvE & cross-play
Choose between Co-Op Assault, Co-Op Warfare and special sorties, and understand why online co-op does not mean the story campaign can be played with a friend.
