The beta version of the game is now available for download in the download section. It is fully playable and working (at least i didnt notice any game-breaking bugs), however there will more solar systems to visit be added in the updates until the final release.
When you download and play this game, please keep in mind you are playing a beta version and, which is why betas are made public, please post any ideas, suggestions, complaints and bugs you may have in the backlash forums.
