The second phase of the Starhawk multiplayer beta begins January 17, allowing PlayStation Plus subscribers to have a go with the hybrid vehicle combat/third-person shooter. Those who participated in the private beta can still play though you must keep using your private beta client.
If you have a Starhawk beta voucher that you received with a copy of Uncharted 3, you can begin playing January 31. Don't have Plus or Uncharted 3? You can try to get a beta invite from the official PlayStation Facebook page starting February 7 or wait until the beta is open to all PlayStation 3 users on February 17.
