The summer is generally slow with releases, making it a great time to catch up on games you missed the first time around. Don't buy those old games just yet, though - they might be cheaper next month.

Sony announced today that they're adding six PS3 games to their Greatest Hits library. The following games will be re-released on June 16th for $29.99 in North America:

• Army of Two
• Battlefield: Bad Company
• Devil May Cry 4
• Gran Turismo 5 Prologue
• Metal Gear Solid 4: Guns of the Patriots
• Ratchet & Clank Future: Tools of Destruction

You could probably find Army of Two and Battlefield: Bad Company for cheaper than thirty bucks now, to be honest. It'll be a price drop for GT5 and MGS4, though.
