After some grade A investigatory work, Colid McFedran writes: "Head on over to the Hong Kong PSN to get the Namco Arcade Beta. You'll get treated to some Home schwag.
Download Namco Arcade from Hong Kong store.
* Play game with your main account (ie the one you go on Home with)
* Get high scores
* Be rewarded with gifts next time you enter home (T-shirts, hats, decorations and up to 4 arcade cabinets for your home.)"
(Pics showing off the Namco gear and arcade cabinets are found in the story)
