If you bought Wolfenstein you get this automatically. Just downloaded it today but have not had time to try it yet!
It's a 10Gb download and I coudn't find a way to do anything other than play multiplayer. Serves me right for not reading sooner. Deleted.
Pookie is sad even though I have Wolfenstein so far I don't have any option to join any beta's. Was it open to just people that pre purchased Wolfenstein?
