Last week’s PlayStation Network update was hard to beat, as it came packed with four full PlayStation 3 games, two PSP games, and a host of game add-on packs and demos. While new full games are by and large absent this week, Sony still has a plentiful offering of bonus packs as well as demos for a few of the PS3’s most anticipated games.

The PS3 edition of BioShock went gold earlier this week in advance of the game’s October 21 release. And as promised, a demo for Take-Two’s dystopian underwater shooter has been added to the PS Store today. The free trial clocks in at a beefy 1.39GB, and will give PS3 gamers a look at some of the tweaks that went into Take-Two’s expanded edition of the Xbox 360/PC original.

A number of other free trials join Take-Two’s sampler on the PSN this week. Brothers in Arms: Hell’s Highway, Ubisoft and Gearbox’s long-in-development World War II shooter, arrived to warm critical reception last week, and gamers can now check out the first mission of the game involving Sgt. Matt Baker and the 101st Airborne Division. Those looking for a more placid demo experience can check out Namco Bandai’s Chopin-tribute role-playing game Eternal Sonata. Two sports demos round out the PSN’s samplers this week: one for Sega’s critically maligned Beijing 2008 and the other for Take-Two’s upcoming NBA 2K9.

With EA’s NBA Live 09 demoed last week, the publisher today added one free and one pricey downloadable game pack to the PSN today. The Oklahoma City Pack is a free download, and includes up-to-date uniforms, logos, arenas, and cheerleaders for the new Oklahoma Thunder NBA franchise. For $19.99, gamers can also enhance their NBA Live experience with the NBA Live 365 pack, which provides daily updates on real world happenings in the league.

EA has also bolstered its Tiger Woods PGA Tour 09 with the Firestone Country Club add-on pack. The $7.49 download gives virtual golfers pro club access to the famous course, which hosts the World Series of Gold as well as the World Golf Championships - Bridgestone Invitational.

And, as has been the case every week since Rock Band’s November 20, 2007, debut, MTV Games and Harmonix have released new songs for its popular rhythm game. The Red Hot Chili Peppers headline this week’s stage, with the band’s 1991 rock funk album Blood Sugar Sex Magik now available for purchase. The 16-track playable album can be had in totality for $19.99, or broken into individual tracks for $1.99 a piece.

Rounding out this week’s list of premium offerings, Namco Bandai has released more DLC for its fighter Soulcalibur IV. Both packs cost $3.99, and give gamers instant access to a variety of weapons that otherwise would have been unlocked through play. Audiophiles may also be interested in the PixelJunk Eden soundtrack, which compiles all of the tunes from Q-Games psychedelic platformer for $2.99.
