Sony already has not one, but two lines of value-package games for the PlayStation Portable. Now as the PlayStation Vita prepares to launch, the company is rolling out one more way to get PSP games on the cheap. Sony announced PSP Dual Packs today, which (obviously enough) bundle together two PSP games from popular franchises for $14.99.

The first three Dual Packs will hit both brick-and-mortar retail stores and the PlayStation Store this week. If you grab the PSN versions, they'll be backwards compatible with the Vita, which lacks a physical UMD drive. The pairs include Secret Agent Clank with Daxter; Syphon Filter: Logan's Shadow with Killzone: Liberation; and Syphon Filter: Dark Mirror with SOCOM: Us Navy SEALs: Fireteam Bravo.

Two-and-a-half years after Syphon Filter: Logan's Shadow hit PSP in October 2007, a PlayStation 2 edition of the stealth-action shooter is headed to retail on June 1, 2010.

Sony Bend, which developed both versions, notes that it "made some important tweaks to the controller," including "a snap button to make getting in and out of cover easier" plus the addition of "'swing out and aim' to L1 to make fighting from combat more intuitive" and word that it has "completely re-tuned the game for the extra analog stick."
