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.
