HOW TO JOIN

Four steps, about ten minutes from nothing to your first dogfight.

No mods, no whitelist, no application. You need GTA V, FiveM and a Discord account, and the whole thing takes about ten minutes.

  1. STEP01

    Install FiveM

    Download and install FiveM from fivem.net if you haven't already. You need GTA V to play.

    • Visit fivem.net and click the download button
    • Run the installer and follow the setup wizard
    • Launch FiveM - it will automatically detect your GTA V installation
    • No mods or additional downloads needed!
    Download FiveM
  2. STEP02

    Join the Discord

    The join queue reads your Discord identity, so Discord has to be running and you have to be a member of the MCS server on it. It is also where support lives and where the flight windows will be called.

    • Accept the invite at discord.gg/qAg9jz3Vmz
    • Keep Discord running while FiveM starts, so FiveM can see it
    • Keep an eye on the Discord: the flight windows will be announced there once they start
    • Boosters, staff and store supporters get queue priority from their role
    Open the Discord
  3. STEP03

    Find MCS Server

    Open FiveM, go to the server browser, and search for 'MCS' or 'Military Combat Simulator'.

    • Open FiveM and click 'Play' on the main menu
    • Use the search box above the server list
    • Search for MCS or Military Combat Simulator
    • Or use direct connect: cfx.re/join/zgkm8y
    Direct Connect Link
  4. STEP04

    Connect & Play

    Click Connect and wait for resources to load. The first load takes three to five minutes because ninety three custom vehicles come down with it. Every load after that takes seconds.

    • Click 'Connect' and wait for resources to download
    • Read the welcome message and server rules
    • Press F1 to open the vehicle menu
    • Choose your aircraft and start dogfighting!

//Flightwindows

When the sky will be full

Two windows a day, at the same hours every day. They are not being flown yet: these are the hours they will run at, so that turning up then means landing in a full lobby rather than on an empty runway.

Europe
Planned
19:00 to 23:00 CET
Americas
Planned
20:00 to 00:00 ET

Once they start, each window will be called on the Discord as it opens, with the live count. The Discord is where the first one will be announced.

//COMMONQUESTIONS

  • Do I need GTA V to play on MCS?

    Yes, FiveM requires a legal copy of GTA V (Steam or Rockstar Games). You don't need GTA Online access.

  • Is MCS free to play?

    Yes. MCS is free, with no pay-to-win and no donation required. Every machine is unlocked from the first connection. The store sells queue priority and cosmetics only.

  • What are the system requirements?

    If you can run GTA V, you can play on MCS! Recommended: 8GB RAM, GTX 1060 or better, and a stable internet connection.

  • Can I play on console?

    No, FiveM is PC-only. You need a Windows PC with GTA V installed to play on MCS.

MCS is one of the easiest FiveM servers to join. Unlike other military servers that require whitelist applications or complex mod installations, MCS uses FiveM's built-in resource system to deliver all aircraft, weapons, and vehicles automatically when you connect. The only account it asks for is Discord, which the join queue reads for priority.
