So chances have it you woke up Christmas morning and scored a PlayStation 4 from your girlfriend or wife, along with a handful games headlined by Killzone: Shadow Fall. Now the question you have to ask is if you’re a PS Plus member. Why is that? Well, Sony is offering the Shadow Fall multiplayer for free this weekend to the very exclusive crowd. How’s that for an extra Christmas gift. Those who apply can download the update from Dec. 28 to Dec. 31. Happy Holidays!
