Pytheas is a galactic exploration, vehicle based, construction game. It has been in development since December 2010. A fleet from Earth's Exploratory Force has gone missing; you are sent to find it. After finding the aptly named ship, Pytheas, you could return to earth, report the find, and let a collection of search and rescue efforts do the rest. However, realizing that is boring, you decide to scour the nearby star systems with your brand new, eerily empty inter-stellar mammoth. Pytheas gives players the tools to execute thier ideas without the limitations of a game engine designed with a different purpose in mind. Barriers that limit how you can play are removed to allow for more freedom.
Here is a short video showing some of the features coming together. There is sound in the game but my sound drivers don't allow any screen recorders to capture it properly. The alpha will be ready soon enough so you'll be able to hear for yourself.
