There's one undeniable fact about next generation gaming: it doesn't come cheap. You'll need $399 just to buy a PlayStation 4, and $59.99 to pick up a retail game like Battlefield 4 or Killzone Shadow Fall. With this in mind, you can save a lot of money by logging into PlayStation Network and downloading some indie titles. With this in mind, we downloaded Resogun, Contrast, Warframe, Flower and Sound Shapes for your viewing pleasure.
