BrewLAN is a mod for Supreme Commander: Forged Alliance that has been in on and off development by a team of one for almost a decade. It adds a wide variety of new units for all factions, as well as offering several new game modes and features. The core design goals for the mod are simple; to add new, interesting, and visually aesthetic units which complement those already in existence and to maximise technical compatibility with other mods.
BrewLAN 0.8. Revision 666. At long last, the beast is released.
If you wish to use BrewLAN with FAF or LOUD, get it from their respective mod vaults. Remove any and all old versions of BrewLAN before beginning.
Inside the 7z file you will find mods, maps, and gamedata folders. The mods and maps can either go in your documents or your game installation folders. Valid directory examples include:
%UserProfile%\Documents\my games\Gas Powered Games\Supreme Commander Forged Alliance\
...\SteamApps\common\supreme commander forged alliance\
...\Program Files\THQ\Gas Powered Games\Supreme Commander - Forged Alliance\
If the folders already exist in the target locations, merge. Maps will already exist if you're doing this in your installation directory, but mods might not. I can't guarantee either will already exist in your documents, but there should also be a replays, savegames, and maybe screenshots folders if you've ever played the game before.
The gamedata folder needs to go in your installation directory, see the last two examples above. There will already be a gamedata folder there, so merge the contents. If the scd files end up with other scd files, then you know they are in the correct place.
If the mod icons appear yellow on the mods list, they are not installed in the correct location, and are probably nested in a way that they shouldn't be. If unit icons, or the new strategic icons are missing in game, you didn't install the scd files for the gamedata folder correctly.
Any other issues, feel free to ask. If you want to be helpful with your troubleshooting questions, run the game in windowed mode, press F9 to launch the log window, un-tick the debug and info messages, and quote the warnings and errors that are shown.
