This week's PlayStation Store Update is now live. The controversial Rock Band Nirvana track pack is here, so all you rockers out there are sure to enjoy the animated Kurt Cobain rockin' it out alive and well in this game. It's a double treat too as Nirvana drummer, Dave Grohl's own band, Foo Fighters, also shares some love in this week's release. Other big releases include Dissidia Final Fantasy for the PSP, Trine's PS3 demo and Ghostbusters: The Video Game on the PSP. Full list awaits after the jump.

The MAG Beta Test for Qore subscribers has been announced to launch on Thursday, so listen up if you want to be in on this action. Starting today, the first wave of voucher codes will be sent out to ALL Qore subscribers, and will continue for the next few days. Details and more after the jump.

Right on schedule, the US PS Store Update has now arrived. Up this week are three new LBP Dynamic Themes (PixelJunk Monsters, PAIN and High Velocity Bowling),a new QORE Episode featuring the much-awaited Uncharted 2, and loads more.

PlayStation Store update rolling in. In this week's lineup is Qore Episode 15, featuring four of the hottest titles coming to the PS3. Map Pack 3 for Call of Duty: World at War (PS3, Xbox 360, PC, Wii) is also in the list, as well as the Old West Map Pack for Call of Juarez.  It's another heavy update for the PlayStation online storefront, so read on and get all the details.

Those who've been keeping tabs on the PlayStation Network's monthly gaming program, Qore, are in for another treat. Following Episode 14's sequel-rich show last month, Episode 15 will be featuring four titles prepping to explode on your PS3 - MAG, Ninja Gaiden Sigma 2, Tekken 6 (PS3, Xbox 360, PSP), and a dose of Katamari Forever to keep the blues at bay.

You know what comes next after the European PS Store Update, yes? That's right, it's the US PS Store Update for the week of July 2, 2009. And it's a hefty one to serve you fine too, in time for the 4th of July weekend. So in case you're feeling a little lethargic to join in on the festivities, at least you'll have something else to do to keep you busy. Among those stashed in this week's goodie bag are add-on packs for MotorStorm Pacific Rift, Cross Edge, the Capcom Classics Collection Remixed for the PSP Store and more. Full list after the jump.

"When a developer succeeds in making an acclaimed title," writes PSN executive producer Kevin Funichi, " the pressure is on to repeat that success. But making sequels isn’t easy. Change too much, and you risk alienating fans of the original title. Change too little, and you’ll be criticized by gamers who want something new." That is just one among the many issues that the devs had to address, so you bet the next Qore episode would be one to watch.

Mark this day, folks, because this is the day Metal Gear Solid officially sets its virtual foot onto the PSOne Classics service. At US$ 10, it's a steal if you just wanna play it. I've seen brand new boxed copies of this game being sold for almost US$ 200. No kidding. Also included in this update are a bunch of new Rock Band and Guitar Hero World Tour tracks. I have a softer spot for the former's picks, though, since it includes Spinal Tap songs. Gotta watch that movie again. It never gets old. Crank that dial up to 11 and check out the full list of new Store items after the jump.

The QJ.NET PS3 blog was chock full of big gaming news again this week, thanks to a whole load of bits about Final Fantasy XIII. Western game devs also jumped into the fray with details from the Sony exclusives inFamous, God of War 3, and Uncharted 2: Among Thieves. They even managed to sneak in a little Sly Cooper teaser in the inFamous demo. With E3 less than a month away, we also saw publishers starting to hype up their offerings for the yearly gaming expo. All that and more in this week's PS3 Weekend Warrior.

From teeny-weeny cyclopic warriors to lean, mean clawing machine, there's a lot of goods for you to choose from over at the PlayStation Store. We've got the update for you here right, and off the bat, I think I'd go for the free demo of X-Men Origins: Wolverine, just in case you haven't checked it out yet.
