The PlayStation Store received a hearty dose of ModNation Racers content this week, as the full title for the PSP, as well as add-on content for PlayStation 3 version, of Sony's kart racing exclusive is now available.

　　ModNation Racers ($29.99) has made its way to the PSP storefront. The kart-racing game affords players the ability to create vehicles and characters and put their skills to the test against up to five others in both ad hoc and online multiplayer modes. In addition, those with the PS3 version of the racer can now pick up smaller pieces of ModNation Racers-themed downloadable content, including a Super Nova Kart ($.99) a Van Mood Mod ($.99), and a bundle of the two ($1.75).

　　Gentlemen, start your engines. Also now available for digital purchase for the PSP today is Hexyz Force ($29.99). Released in Japan six months ago, Atlus' role-playing-game has made it to North America. The third and final PSP title to become digitally available in the PlayStation Store is Pinball Heroes Bundle 2. Available for $9.99, this pinball sequel includes new tables based on popular Sony franchises, including ModNation Racers, MotorStorm, Fat Princess, and Wipeout.

　　If the above are a bit pricy, Sony added a duo of PSP Minis titles to its store today, including VT Tennis ($4.99) and Robin Hood: The Return of Richard ($4.99).

　　Also debuting in the PlayStation Store this week are two new PS3 titles. First, Soldner-X 2: Final Prototype ($12.99), a shoot-'em-up sequel to 2008's Soldner-X: Himmelssturmer, with seven distinct levels is now available. Next to it is the PSN-exclusive Super Stacker. The $9.99 puzzler has more than 100 levels, including both adversarial and cooperative multiplayer modes and more.

　　One PSOne Classic hit the store this week, as the 2002 first-person shooter Delta Force Urban Warfare is now available to download for $5.99. As its name and series history suggests, the game is full of urban environments and explosive weaponry.

　　Downloadable content for Guitar Hero this week includes songs from Disney's pop trio of Demi Lovato, Selena Gomez, and Miley Cyrus, while the Rock Band catalog welcomes Pantera's entire 1996 album The Great Southern Trendkill. And for those who aren't fans of pop or '90s metal, a demo for MTV Games and Harmonix's upcoming Green Day: Rock Band is now available to download.

　　A full list of the week's deals and new PlayStation Store content, including themes, wallpapers, demos, discounts, and add-on content, is available on the official PlayStation Blog.
