The key to all successful combat missions is great teamwork and overwhelming firepower! Ace Combat Infinity’s multiplayer mode will challenge you to work with a squadron of friends to either go head-to-head or cooperate with other squads to dominate the skies.

Ace Combat Infinity’s "Online Co-op Missions" is a completely new mode to the series challenging four players to create one cohesive squadron to either work with or compete against another rival team. Players will then take-on missions specifically designed for this mode heightening the need to work as a unit to destroy enemy troops or take out an enemy troop base, etc.

The winning air combat strategy is in the hands of each pilot within each team. Players can decide to challenge stronger AI enemies with allied squadrons first or go after targets that the rival teams did not destroy to rack up more kills. Players and their teams will decide on their main mission goals as well, from accomplishing a huge mission task by cooperating with other squadrons to going completely head-to-head against rival flight squads to outscore them to demonstrating their superior team dynamics by providing superior wingman skills to ensure the team returns to base victorious.

Ace Combat Infinity allows players to use rewards gained from playing the "Online Co-op Missions" to obtain their favorite aircraft and enhance them. The more a player plays online with friends, the more strategy they will be able to use to gain a larger variety of aircraft and special weapons.

As was announced last year, Bandai Namco Games has shut down the servers for Ace Combat Infinity.
