BrewLAN is a mod for Supreme Commander: Forged Alliance that has been in on and off development by a team of one for over half 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 maximize technical compatibility with other mods.
BrewLAN version 0.4.3 beta. Released partially as a hot-fix, as this version corrects the BlackOps Unleashed incompatibility. Installation should be pretty straight forward; remove the old version, put BrewLAN folder in the mods folder, and the SCD file in the gamedata folder. You should know the drill by now. Detailed installation instructions can be found on the Google code page for BrewLAN, on the Downloads tab.
