From an email i recently got from them:
We’re very excited to announce that Star Citizen Alpha 2.0 is now available for all players! This release includes the very first elements of Star Citizen’s Persistent Universe, including large world maps, multi-crew ships, FPS combat and more!
We invite you to explore a multitude of new locations around the gas giant Crusader. Start your journey at the massive Port Olisar transit station and then play alongside friends and enemies as you explore scenic asteroid fields, complex communications arrays, research satellites and even a derelict space station.
This release also adds a variety of flight-ready ships, including the powerful Retaliator bomber, the mighty Constellation Andromeda and new variants of the Avenger fighter. This is our biggest release yet, introducing everything from interior physics grids, quantum travel, EVA, first person combat, missions and much, much more.
Alpha 2.0 is the foundation for the Star Citizen’s Persistent Universe, and we’re extremely proud to allow backers this early look at a major milestone in building the BDSSE! Welcome to Crusader: it’s time to get back into space!
