Gamigo, the developer of Black Prophecy, one of the most beauifully rendered Space Games I ever saw, is opening up it's BETA participation. You can sign in and Test-Play the Game for Free and help them improve it. 

"Black Prophecy is the first Sci-Fi Space MMOG that dares the step towards action-oriented gameplay from a third-person and first person perspective. Register for the upcoming Closed Beta and be one of the few that get a first glimpse of Black Prophecy and help us improve the game's quality."

Go to Black Prophecy and sign up, just taking a look at the pictures you will know how good this game can be.
