Fresh out of the blocks, Sony is now adding to its downloadable demo service with the introduction of Killzone: Liberation, which takes top billing beside other available game demos including Mercury Meltdown, MotoGP, Ridge Racer 2, World Tour Soccer 2, and the award-winning LocoRoco. Plus, beyond that already decent selection, other titles set to arrive include the likes of SOCOM: US Navy SEALs: Fireteam Bravo 2, and Syphon Filter: Dark Mirror.
