Little Big Planet's PlayStation Move compatible spin-off, Sackboy's Prehistoric Moves, will be available for free download to PlayStation Plus subscribers. According to Eurogamer.com, the game will be available to Plus users a week before the game's release, which is December 15th. Let's see here, the 15th, minus a week, correct for wind, carry the one... That's today!
As an added bonus, Plus subscribers will also be getting an extension on the the Little Big Planet 2 beta. The European PlayStation Blog says: ""This is just the start of the December treats so keep your eyes open for another update very soon." On top of all that, two new Dead Nation avatars are available, as well. PlayStation Plus is looking more tempting with each update.
