PlayStation Now's open beta will begin July 31 in Canada and the U.S., bringing cloud game streaming to PlayStation 4, Sony announced during its E3 2014 press conference.

It will follow on PlayStation 3 and PlayStation Vita shortly thereafter. Those without a PlayStation device will be able to access PlayStation Now using the PS3's DualShock 3 controller and select Sony televisions.

Players with access to the beta will have access to more than 100 games. Those include Dead Space 3, God of War: Ascension, Metal Gear Solid: Ground Zeroes, Ratchet and Clank: Into the Nexus and Ultra Street Fighter 4. Publishers signed up for the streaming technology include Activision, Capcom, Electronic Arts, Take-Two, Square Enix, Warner Bros. and more.

Sony acquired Gaikai, the game streaming service, in 2012. When Sony revealed the PlayStation 4 in February 2013, Gaikai CEO and founder David Perry took the stage to say that Sony would use the service to bring features like instant streaming demos to the PlayStation Network.

Sony officially revealed PlayStation Now during the 2014 Consumer Electronics Show in January, the cloud-based service will allow users to stream PlayStation 3 games like The Last of Us and God of War: Ascension to PlayStation devices and compatible Sony Bravia televisions, like Netflix subscribers do with video and Spotify users do with audio. Last month, Sony announced that the video game streaming service's private beta would arrive May 20.
