Download the current demo and try the game for yourself. The installer auto-updates itself, so once you download and install Miner Wars, you will be notified when a new build comes out. Consider buying full game for discounted price and get even more frequent updates, extra features and much more - plus you support the indie developers with their ongoing production of Miner Wars! The final release is scheduled for Summer 2012.
