What you get on MCS

  • The airframes Ace Combat made famous, flyable now: F-22A, F-15, F-14, Su-57, Su-27 and Su-35, Typhoon, Rafale, Gripen, F-35.

  • Arcade handling with the tools that make a dogfight readable: radar, lock tone, flares, a kill feed and a scoreboard.

  • A 1v1 dogfight arena and ranked matches from 1v1 to squads, first to ten kills, so every fight has a result.

  • Helicopters and armour when you want a different fight, and two evening flight windows being set up so that a full lobby has an hour you can plan around.

What you should know first

  • There is no campaign, no story and no cutscene. Every fight is against people, and people are less forgiving than a script.

  • It runs inside GTA V through FiveM. You need GTA V on a Windows PC; there is no console version.

  • The flight model is GTA physics tuned for combat. It reads like an arcade sim; it is not a copy of one.

  • The first load takes three to five minutes. After that the server puts you in the air within a minute.

Ace Combat is a trademark of Bandai Namco Entertainment. MCS is an independent FiveM server with no connection to it, and the comparison above is our own honest reading.
