The Playstation Blog has announced multiplayer will be free for North American PS4 owners this weekend, conveniently timed around the release of Battlefield Hardline.
From midnight 20 March PDT to midnight 22 March PDT North American Ps4 owners will have free access to all online multiplayer features of the Playstation Network. Unlike the previous Australian free weekend this will not include all PS Plus benefits such as free games, just the online multiplayer component.
Word is this is for North America only, Europe, Australia and the rest of the world will miss out this time. Check out the Playstation Blog for more info.
