While not quite as stellar as last week's massive PlayStation Store update, this week still manages to pack a punch in the add-on content department. Up for grabs now is two Soulcalibur IV weapon sets priced at $4 each, along with the usual round of Rock Band tracks and a free Oklahoma City pack for NBA Live 09. Moving on, PS3 owners can experience BioShock for the first time as a playable demo is now available on the store. Other demos for this week include Brothers In Arms Hell
