A remake of the 2010 space game Galaxy on Fire 2 by FISHLABS in Unity 6, for Windows (also as a UWP app), Linux and Android. It aims to be a faithful port of the original gameplay, including flight, combat, trading, mining, stations, the bar and the whole story. It is built on the original assets and on game logic ported from the decompiled game code. Downloads are on the releases page; each release says how to install it.

Status: the main campaign, the Valkyrie add-on and the Supernova add-on can be played from start to end. The Supernova opening and final battle have been rebuilt from the original scripts, but the add-on has not been fully played through yet. Multiplayer is experimental. A build's version is the date and time of its release (for example 2026.10.01.1200), the same on every platform, shown in the main menu.

• Story: the full main campaign with the prologue, the Void and the ending, plus the Valkyrie and Supernova add-ons. Dialogue is voiced (English or German), with portraits, radio chatter and cutscenes.
• Flight: the original flight model and chase camera. The station orbits are rebuilt exactly like the original, with their skies, planets, suns, lens flare and asteroid fields. Travel covers the autopilot, planet jumps, fast-forward, the star map, jumpgates, the Khador Drive and the Void's wormhole.
• Combat: every weapon, including missiles, beams, EMP, mines, turrets, sentry guns, the Liberator and the other special weapons. NPC traffic and AI, capital ships, pirate bases, Specters and the Most Wanted criminals. Combat equipment: cloak, emergency system, time extender, repair beams and gamma shields.
• Economy and stations: hangars, shops and ship dealers, and the space lounge with bar agents and every freelance mission type. Also blueprints, wingmen, medals, the Kaamo Club and save games.
• Mining: asteroid mining with the drilling minigame, plus gas clouds, hacking and docking at objects.
• Multiplayer (experimental): a shared universe, online through a server browser or a join code, or over a local network. Players can host from the game or run a dedicated server. Players see each other in space and in the hangars, and can fight each other. Squads share bar missions and their rewards. Everyone shares the NPC traffic, the crates, the asteroids and the shop stock. Local and global chat.
• Remake extras:
  • Arrival and take-off flights in the hangar, animated dialogue text, and the original-style bloom as an option.
  • Four difficulties (Easy, Normal, Hard, Extreme) that can be changed during a game, and a choice between the PC and Android economies for a new game.
  • Other ships' engines like the player's (an option), upscaling (FSR 1, STP), photo mode and screenshots.
  • Discord Rich Presence on Windows: your Discord status shows what you are doing in the game.
  • A Dutch translation, and a choice between German and English voices.
  • Debug tools (Options > Gameplay): jump to any story step, cheats, give items, spawn ships and objects.
  • Export and import of all save games as one file (Options > Gameplay in the main menu), to move your games to another PC or phone. Importing checks the file first and replaces every existing save.
• Controls and screens: touch, tilt, keyboard and mouse, and controllers (shown with Xbox buttons), all rebindable. Gyro steering with a DualSense, DualShock 4 or Switch Pro Controller on Windows. Haptic feedback on controllers and Android phones (hits, collisions, explosions, weapons, boost, jumps and mining) with an intensity setting. Landscape screens from 4:3 up to 32:9, phones included.

1. Install Unity 6000.7.0b2 (Unity 6.7) with Unity Hub. Add Android Build Support if you want phone builds.
2. Clone the repository with Git LFS installed. The assets are about 2.1 GB in LFS.
3. Open the project in Unity and open Assets/Scenes/MainMenu.unity, then press Play.

The scenes are MainMenu (build index 0), Space (the flight level) and Station (docked). The GoF2 menu in the Editor holds the asset build tools. The generated assets are already in the repository.

Always switch the active build profile (File > Build Profiles > Switch Profile) before building another platform. URP chooses which shader variants to keep from the active platform. An Android build made while Windows was active renders black, so the editor script BuildTargetGuard refuses such builds. BuildVersionStamp gives every build its date and time as its version; for a release, set the Editor process's GOF2_BUILD_VERSION environment variable so all platforms get the same one.

Multiplayer is experimental. Everyone in a session shares one universe: you see each other in space and in the hangars, form squads, and fly bar missions together. Every player starts a fresh free-play game docked at Var Hastra, and sessions don't touch your single-player saves. Only the exact same game version can play together, so everyone needs the same release.

1. In the main menu, open Multiplayer and type your pilot name at the top.
2. The server browser lists the public games with their name, host, players (for example 4 / 16) and version. It refreshes every 5 seconds. Click a game to join it.
   • A game tagged PASSWORD needs its password: type it in the Password field under the list first.
   • A game on another version shows "needs " and can't be joined.
3. To join a game that isn't listed, type its join code (six letters or digits, like QKJH9N) in the field under the list and press Join. On a local network you can type the host's address instead (192.168.1.20, or 192.168.1.20:7778 for another port).

On the Host a game card, pick a mode:

• Public: online, and listed in the server browser under the Game name you choose.
• Invite only: online, but not listed. Friends join with your join code.
• Local network: for players on the same network (or a VPN like Hamachi or ZeroTier). The card lists your addresses (tap one to copy it) and the port, 7777 by default.

Every mode can have a password and a Max players limit (2 to 100, you included). Debug menu (Off by default) decides whether the players may use the Debug menu (cheats, items, spawns) in your session. Press Host. In an online game the join code is copied to your clipboard and shown under the station's system information, with a Copy button. Online play goes through Unity Relay: no port forwarding, but it needs an internet connection. With a player host, all traffic goes through the host's connection, so for big sessions a dedicated server is better.

A dedicated server hosts a session without anyone playing on that machine. It uses the normal Windows or Linux download; no extra files are needed.

Windows

1. Open Start Dedicated Server.bat in the game folder with a text editor (Notepad), and set:
   • NAME: the game's name in the server browser.
   • PASSWORD: leave it empty for none.
   • MAXPLAYERS: the player limit, at most 100.
   • ALLOWDEBUG: 1 lets the players use the Debug menu (cheats, items, spawns); 0 (the default) turns it off.
2. Save the file and double-click it. A console window opens; the game itself runs without a window and without sound.
3. The console shows the join code, and the game appears in everyone's server browser.

Linux

1. Edit NAME, PASSWORD, MAXPLAYERS and ALLOWDEBUG at the top of start-server.sh in the game folder.
2. Run it in a terminal: sh start-server.sh. The terminal shows the join code and the log.

The console

The console shows who joins and leaves, where each player is, and the chat. Only the server can run commands; players can't. Type one and press Enter:

Starting it by hand

The launchers only start the game with these options, which you can also use yourself:

GoF2Remake.exe -batchmode -nographics -server -relay -name "My universe" -password secret -maxplayers 32
./GoF2Remake.x86_64 -batchmode -nographics -server -relay -name "My universe" -logFile -

Good to know:

• A local network server (without -relay) needs UDP port 7777 open in the firewall for the other players.
• The server keeps the shared world: the shop stock, squads, missions and chat. Each orbit's NPCs are run by the first player who arrives there, so the server itself needs very little CPU.
• Players on a different game version are turned away with a message saying which version the server runs.

Every flight control can be rebound in Options > Controls (two keyboard / mouse keys and a controller button each). Controllers and touch are fully supported. The in-game hints show the buttons for whichever input you last used.
