Update: Yakuza 5 is no longer free, instead being replaced with Fat Princess as originally advertised.
Original: Sony has posted up this month's PlayStation Plus games Furi and Saint's Row Gat Out of Hell for PS4. There's a little surprise too though, as Yakuza 5 for PS3 is also free for PlayStation Plus Subscribers.
Fat Princess was supposed to be one of the free games for PS3 this month, but still seems to have a cost assigned to it, so it's likely that this is a mistake which will soon be sorted. So it's probably best to grab it while you can.
Other games free this month include Call of Juarez: Bound in Blood, Prince of Persia: Revelations for PS Vita and Oreshika: Tainted Bloodlines, also for PS Vita.
Go grab your games today.
