Supreme Commander 2 is a real-time strategy (RTS) video game developed by Gas Powered Games and published by Square Enix. It is a sequel to Supreme Commander. A PC-only demo was initially released via Steam on 24 February 2010, with the full game released on 2 March 2010.

A Mac OS X version of Supreme Commander 2 was announced by Mac games publisher Virtual Programming in May 2010. They released the Mac OS X version of the game on 24 September 2010 and released the Infinite War Battle Pack for Mac OS X in January 2011.

The story starts with the newly-elected President's assassination, causing the breakup of the coalition formed during the expansion of the first game.

The first campaign (dedicated to the UEF (United Earth Federation)) follows Dominic Maddox, a UEF officer who is married to an Illuminate. Maddox fights off Cybran until the UEF Commander he serves declared that all Illuminate are terrorists and orders him on a mission to "round up" the Illuminate from his home city. Maddox refuses, goes rogue, and decides to go on his own campaign to remove his old commanding officer from power. Immediately following the defeat of the UEF Commander, he discovers a portal that leads to Seraphim VII, unlocking the second campaign.

UEF has not been a contender in any CBUB matches.
