Sirius Online

Explore a vast and unique universe in this Freelancer-Inspired Action MMO. Combat your friends, harvest ores and explore the outer rims of the Sirius systems. But beware - not every player is a friendly one.

Sirius is an online-only game and requires an Internet Connection.

Based on the highly loved Mouse/Keyboard controls of Freelancer, combined with a balanced universe and a low-entry-barrier, Sirius can be enjoyed and played by almost everyone.
