The news post on the Roberts Space Industries website covers the release of a new version 2.2.alpha patch for Star Citizen, and announces that another free fly week is underway to allow folks to check out the current state of the upcoming space combat game. Here's word:

On the fence about Star Citizen? Why not give it a try and see what we’re building! For the next week, we’ve enabled Free Fly access to all accounts… FOR EVERY CURRENTLY FLYABLE SHIP IN THE GAME OO-AH-AH-AH-AH! This means that anyone can jump in to Star Citizen Alpha 2.2.2 today and fly limited ships like the Scythe, Mustang Omega, and more! The Free Fly event gives everyone access to three unique parts of the Star Citizen experience:

• Star Citizen Alpha 2.2.2 – Also known as Crusader or the “mini-PU,” this is the nucleus of the world we’re building! Featuring multiple space stations and environments, scripted missions, places to explore and more, Alpha 2.2.2 is your first look at a much larger universe!
• Arena Commander – Arena Commander is a ‘game within a game’ that we’ve used to develop our flight mechanics and ship combat balance. Take on human opponents or an AI swarm in single seat fighter.
• Social Module – Interact with other players while you explore our first landing zone, ArcCorp! The Social Module is intended as a starting point for our world building,

You can register for an account here to get started. If you already have an account from a previous Free Fly, you’re all set! Just log in via the Star Citizen launcher. This is the first Free Fly that includes Crusader, so there’s more to explore than ever before. For the next week. Free Fly accounts will have access every ship currently available in the game.
