'Zuma' arrives on PlayStation Network

PopCap puzzle title Zuma has been released as part of this week's PlayStation Network update.

Zuma, which is the first game by PopCap to be released for the PSN, can be downloaded for £6.99.

Also available is space shooter Super Stardust HD, which has been reduced to £1.59 following its two-year anniversary.

Rock Band sees the release of Maroon 5 and Warped Tour track packs, while Guitar Hero welcomes a Phish song pack.

Sony has also revealed plans to enhance its PSN service, which CNN reports will see all Sony devices interconnected.

The new "broader" PSN will make the storing and sharing of files easier to accomplish, with customers rewarded for brand loyalty with discounts and other perks.

The new service is expected to launch next spring.
