For a limited time, when you purchase a PSPgo system, you’ll have access to a PlayStation Network downloadable voucher for Rock Band Unplugged Lite. This lite version of Rock Band Unplugged will allow you to play five full tracks. Plus, you can create your own personalized version of the game by purchasing your favorite Rock Band songs from the PlayStation Network. Now the only instrument you’ll need to rock anywhere is the PSPgo system!

Again, quantities are limited so be sure to mark your calendar for October 1.

So, how does Rock Band Unplugged work on the PSP, you ask? For a quick first look at the game, check out the trailer below.

Rock Band Unplugged creates a full band experience in the palm of your hand by combining key gameplay elements from both Rock Band and Rock Band 2, inclusive of familiar, as well as all-new songs. It introduces new and unique features specifically designed for the PSP, and will also leverage the system’s Wi-Fi capabilities through the first fully-featured in-game store for additional downloadable songs on the PSP. In short, your hands are the “peripherals” as you follow a challenging sequence of colors and lights, rotating between the lead/bass guitars, drums and vocals in an intense attempt to keep your respective instruments at the highest level possible. Simply tap on the D-pad and Face buttons to control each instrument, but keep in mind this is no easy feat!

In addition, Rock Band Unplugged will launch the following tracks exclusively on the PSP:

• 3 Doors Down – “Kryptonite”
• AFI – “Miss Murder”
• Alice in Chains – “Would?”
• Audioslave – “Gasoline”
• Black Tide – “Show Me the Way”
• Blink 182 – “What’s My Age Again”
• Freezepop – “Less Talk More Rokk”
• Jackson 5 – “ABC”
• Tenacious D – “Rock Your Socks”

We’ve said it before and we’ll say it again — 2009 is going to be an impressive year for the PSP. For those of you who don’t own a PSP yet, now is the time. For those who currently own the PSP, we hope you enjoy!
