Damn right i will, i'mm chomping at the bit for another chance to play, couldn't get enough of the alpha, so the beta certainly wont burn me out for the full game.
Loved the game in Alpha, can't wait to see what changes are made in the Beta if I get in there as well. I don't think there's such thing as spoiling here.
I got an invite to the alpha and really enjoyed the game. I only got to play about 5 hours of the alpha but it was a really unique gaming experience. Very different than any game i usually play.
I might change my mind of my first post, that I would probably play the Beta :P
But wont be sad if I do not get a invitaion to not test the Beta. Would really like to see if the connection / server issues will be fixed. And if its balanced / will get balanced.
