StarDrive is now available for pre-purchase on Steam, offering the chance to get a 15% discount on Zero Sum Games' upcoming 4X space strategy game, as well as immediate access to the game's beta testing (thanks Mark). There's a StarDrive Beta Mission Statement on the game's website outlining the goals for the beta. Here's word: "StarDrive has a solid foundation and this Beta will demonstrate to you the full power of our engine. I am making this game for you. So tell me what you want. The best ideas that have the most support will get into the game. First I want to focus on usability features - things to make your life easier. But I also want to add more meat to the areas you most enjoy."
