02 / PRE-FLIGHT

From download to deployment.

For now, ask the alpha organizer to invite your email before attempting online sign-in.

  1. 01

    Prepare your game files

    You need a Windows PC, your own installed copy of Supreme Commander: Forged Alliance, and the matching FAF 3839 files. Setup checks that exact build. A newer FAF build may not match.

  2. 02

    Extract and set up

    Extract the entire ZIP to a writable folder on your storage drive. Open Set up GCE.cmd and select your Forged Alliance and FAF data folders. Keep the downloaded folder structure together.

  3. 03

    Sign in to the alpha

    Open Play GCE Online.cmd. Request a code using your invited email, then enter the code and choose a player name. Sign-in happens in the Windows client.

  4. 04

    Assemble your team

    Find your friend by player name and accept the request. Create a shared campaign, choose your ACUs, and join the same lobby. Both players ready up; the host deploys. Keep the online window open.

IN THIS BUILD

Three deployments. One starting point.

CO-OP MISSION DEMOS
01

Silent Relay

Your first deployment. Complete the mission to unlock basic T3/T4 schematics for the participating commanders.

02

Relay Defense

Continue together after both commanders have completed Silent Relay. Protect the objective and hold your ground.

03

Safe Harbor

Defend UEF civilians from a rogue Cybran commander. Expand the battlefield and pursue optional objectives for additional rewards.

03 / STAY MISSION-READY

Updates without
starting over.

Online progress belongs to your account. Downloading a new client does not reset your server-saved commanders or campaign results.

Updates are manual in this alpha. Automatic patching, signed updates and local-save migration are still to come.

LATEST

0.7.0-alpha.1

  • Hosted email-code sign-in, friends and private campaign lobbies.
  • Four starting commanders and server-saved mission rewards.
  • Same-faction research sharing for a joint deployment.
  • Fixed the hidden panel that blocked sign-in text fields.
Download this release
How do I install an update safely?
  1. Close GCE and the game, then back up your current installation.
  2. Extract the new package into a new folder. Keep the old folder and its profile intact.
  3. Run setup in the new folder, then sign in with the same email to load your online progress.

Local workshop saves and replays are not automatically moved to the new folder. Keep the old installation until local-save migration is available. Never replace your profile with another player's files.

YOUR COMMAND RECORD

What follows your account?

Saved on the GCE server

Your account, friends, online commander progress, shared campaigns and confirmed mission rewards. Online research borrowed from an ally lasts for that deployment.

Kept on your PC

Your current local commanders and workshop choices, game settings, replays, logs, and installed game files. Local saves are separate and do not automatically sync to the online account.

Do I need an invitation to download?

The package is available here. Online play is limited to invited accounts while the alpha is being tested. Downloading does not create an account or grant an invitation.

Does this package include Forged Alliance?

No. Every player needs their own game installation. This package also currently requires the pinned FAF 3839 files. GCE uses that fixed balance baseline and does not automatically track later FAF releases.
