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.
