What is Sirius all about? Its a Game. Seriously. Think about Freelancer. Now add the third dimension into the content. Speed it up. And add cool fluff like Scanning for Belts, deep space exploration and possibly even more. Started as an ambitious project in 2005, with a lot of drawbacks we finally got Multiplayer working in mid June 2014. Shoot, Mine, Explore and Manage the galaxy - coming soon.
Carrier made for Orion faction, weapons and engines to be mounted. It uses highly advanced technology which means it has overcome typical JET engines and moved onto Anti-gravitational force + Plasma(similar to Tesla engine used by Canis) for highspeeds.
