As usual, all six titles will be available free as of the first Tuesday of the month, Sept. 2.
PlayStation 4 owners will be able to get FuturLab's Velocity 2X and Die Gute Fabrik's Sportsfriends for free. Velocity 2X includes cross-buy support with its PS Vita version, and customers who download Sportsfriends on PlayStation 3 will also receive the PS4 version at no additional cost.
The two free titles for PS3 owners are PlayStation All-Stars Battle Royale from SuperBot Entertainment and Hoard from Big Sandwich Games. PlayStation All-Stars is a cross-buy title, so PSN users can also pick up the PS Vita version. And on PS Vita, Hello Games' Joe Danger and Llamasoft's TxK are both free next month.
PlayStation Network users still have a few days left to pick up the six free games from August.
