7. Contrast
Now filling the large shoes left when PS4 exclusive racer DriveClub was shelved until next year, Contrast is the second game on this list that is completely free to Playstation Plus subscribers on PS4. Contrast plays on the effects of light and shadow to create a unique 2D and 3D platforming game that takes heavy inspiration from film noir. It's certainly a very different experience from Driveclub, but no less worthy of your attention. This unique title will also be available on Xbox 360, PC and Playstation 3 when it releases on November the 15th in North America and the 29th in European territories.
