This phase of the beta will be open to everyone, both closed beta players and the public. All that's required is the new Requiem client, which can be downloaded from the playrequiem.com website, and a Requiem account. All prior accounts will be reset, and all new characters will start off in a totally new tutorial space called Turba Island.
This change already addresses one of the large gripes from the previous test - the lack of a decent tutorial space. It seems that Gravity has been listening to all of the feedback they've received about Requiem during the closed beta, and are working to improve upon their game. However, only time will tell as to what else has been changed and added to by the Requiem team.
