Just found this cool free Halloween mask for all you LBP gamers. Its a cool new costume to put your Sackboy in.
EDIT: Have just found 4 more free downloadable costumes that I will display in the comments box below.
To get your Sackboy costume simply go into Playstation Store, click Latest Content and scroll down to find the LBP downloadable content where you can download the free Halloween Mask.
Alternatively you can find Little Big Planet in the A-Z listing of games on the Playstation Store.
From the Store:
The best thing about Sackboy is that you can make him look and act exactly how you want. Download this additional costume to make hime really stand out from the crowd.
Note: to download this additional content you must already own LittleBigPlanet.
