Infamous 2 Mission Creator Beta[]
If you are a US resident and visited infamousthegame.com between March 14 and March 21, you had a chance to sign up for the inFAMOUS 2 mission creator beta. A few people were randomly picked to beta test the mission creator. The beta started April 12, and Sucker Punch has said that the best missions will be online the day the game is released and before anyone else uses it.[1][2]
Uncharted 3 Beta[]
The normal open beta for Uncharted 3 multiplayer opens on July 5, but members of PlayStation Plus and those who purchase a new copy of inFAMOUS 2 get early access on 28.[3]
