Sony’s game streaming service PlayStation Now has been available in beta for months, allowing PS4 gamers to stream last-generation PS3 games on their shiny new consoles. As of today, PS Now is officially released in earnest and comes with more ways to play. In beta, gamers could only stream games a la carte, and pricing depended on the title and how long you rented the game for. Today, the service supports a subscription model; PS4 owners can cough up $19.99 for one month or $44.99 for three months of back-catalog gameplay. PS Now currently provdes “instant and unlimited access to a catalog of more than 100 PS3 games” with more on the way. This new model is launching exclusively on the PS4 first, and Sony promises it will reach other PS Now enabled devices in the future. Want a taste? The company’s offering a free seven-day trial to the subscription program; get it here or fire up your console.
