Vega Strike

Vega Strike is an OpenSource 3d space simulator which allows players to explore a vastly dynamic universe where frontiers collide and you're just a pilot trying to make ends meet.

Vega Strike is designed as a non-linear gaming experience, where you choose what action you want to take. Vega Strike features a dynamic trading economy, allowing your character to operate as a merchant. Discover what trade routes bring in the most profit, what commodities make you the most money given your ship's cargo space limitations, accept cargo missions and learn to avoid areas of danger.
