If you're yet to jump aboard the PlayStation Plus gravy-train, then you've already missed out on a free copy LittleBigPlanet.
But worry not, SCEE's got a new goodie to tempt you into a 12-month subscription; a free copy of Ratchet & Clank: Quest For Booty. The game will be available for free to anyone who places a yearly subscription for PlayStation Plus between the September 1st and October 5th.
In addition, SCEE's detailed the PlayStation Plus bonuses subscribers can expect through September and October. You can get all the information over on the PlayStation Blog.
