This week's PlayStation Store update is now live and the PSP is receiving a nice piece of content. A new Patapon 3 demo allows you to test the game's multiplayer.

The 110 MB demo features both competitive and cooperative play. You'll get a taste of some of the new enemies and "Super Hero" Patapons. It can be played online or via wireless ad-hoc.

Patapon 3 is expected later this year exclusively on the PSP.
