Sirius Online is a space-based MMO inspired by Freelancer. Explore Space alone or together with friends and find adventiure, riches or new enemies. Build a gigantic empire or stay a lone assassin for hire. Be a pirate, killing helpless miners or assemble Fleets to protect your friends. Everything is build and destroyable. Divelanes, Stations, Ships... you name it, you (almost always) build it.
Together with a really responsive, action oriented control scheme, professional voice acted tutorial, loads of space, Sirius is surely a game to remember. And to kill other players, obviously.
