PlayStation Plus will enter an open weekend from Friday, February 13 6.00am GMT/7.00am CET until 6.00am GMT/7.00am CET Monday, February 16.
According to the PS Blog, even if you are not currently a PlayStation Plus member, you will be able to play with your friends online this weekend for free. That said, the usual restrictions apply, so you won't be able access the PS Plus monthly games, Store discounts and Cloud Storage.
A free multiplayer weekend gives you the chance to try Dying Light's "Be The Zombie" mode if you haven't already.
