Starting today, the third beta phase of Sins of a Solar Empire will go live, introducing multiplayer functionality and a whole host of new features to the RT4X space-strategy game. Those who wish to enter the beta can do so by pre-ordering the game before September 26 for immediate access.

The game itself is set for release during February 2008. It puts players in charge of one of three different factions as they explore star systems, expand their empire, exploit conquered planets and exterminate rivals, among other things.
