Sony will launch the PlayStation Now open beta on PS4 on July 31 in the US, the company confirmed on Monday. The open beta will come to PS3 and Vita 'shortly afterwards'
Announced during the Sony E3 press conference, the PS Now cloud gaming service will allow beta testers to go hands-on with around 100 PS3 games.
Among the games playable on the service will be Dead Space 3, God of War: Ascesion, Metal Gear Solid 5: Ground Zeroes, Ultra Street Fighter 4, Ratchet and Clank: Into the Nexus.
The firm also announced that 'later this year' the PS Now beta will also be made available via "select Sony televisions", with users needing only a DualShock 3 controller to play PS3 games on their TV via the cloud.
The streaming game service was previously launched in closed beta form, originally limited to PlayStation 3 before the closed beta hit PS4 in May.
Revealed at CES in January, PS Now will stream PS3 games to PlayStation systems, Bravia TVs and, in the future, other Sony and non-Sony devices. More games from across the PlayStation hardware family will follow.
Users can rent games for one, seven, or 30 days using PS Now. Alternatively, a yet-to-be-revealed subscription will provide full access to the streaming library.
It has been reported that the PS Now European launch won't occur until the first quarter of 2015.
