To date, what little you could play of Star Citizen has existed in bits and pieces: a dogfight module here, a hangar there, but not the cohesive interstellar experience promised from the start. At last, though, things are coming together. Roberts Space Industries has given backers an Alpha 2.0 release that represents the "first true slice" of the crowdfunded (and much-hyped) game. You can travel between multiple locations around a planet, and first-person ground combat is possible for the first time. Space walks are even an option, if you dare leave the safety of your ship.
