Come be the new Mayor in SimCity! The second SimCity Closed Beta has begun and will continue until 6:01am PST on Sunday, February 17th. The SimCity Closed Beta offers fans the chance to play a one hour slice of the game while we stress test our servers before the game launches March 5. Beta players can play the one-hour slice of the game multiple times during the beta period.
