If you happen to play DaS on a PS3, the sign-ups for the DaSII beta are now open. Apparently, all you have to do is download the Dark Souls II Beta Registration Ticket from the Playstation Store. The first beta will be held on the 12th October, whilst the second will be on the 27th, and will be accessible to all North American, European, Japanese, Australian and New Zealander PS3 owners. NamcoBandai has advised players to pay close attention to the Dark Souls II Facebook page for more details regarding the beta.
There's currently no word on whether there will be an Xbox or PC beta at this stage.
Update: The North American beta is a select-entry event, and is limited to approximately 1000 people.
