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.
Upgrades from the EG 900 Fusion Reactor, or is built directly by the UEF Tech 3 Field Engineer. It has the capability to build 4 T1 buildings: Energy Storage, Point Defence, Anti-Air Turret, and Torpedo Launcher. Of the three defences it will auto build them in a random position around it when attacked by the appropriate things.
So this is like the upgrades from supreme commander 2 tech tree that cool.
This is better than SC2's imo.
