If you haven’t subscribed to Playstation Plus yet, but have been wanting to try games like Destiny and Diablo III online, now is your chance.
Starting September 26th, all PSN users will have free access to online multiplayer through September 28th. A free PSN account will be required in order to take advantage of the free multiplayer weekend. Unlike Sony’s past consoles, a Playstation Plus membership is required in order to play (most) online multiplayer titles.
