Top downloadable titles Flower, flOw, Escape Plan and Sound Shapes will all be available for download on PlayStation 4 at the console's launch.

Better yet, the quartet of titles will be completely free for existing owners regardless of the platform they were originally bought on, Sony announced via the EU PlayStation blog.

The PS4 editions will see some upgrades too - Flower now features 1080p 60FPS visuals, while PlayStation Vita title Escape Plan has re-worked controls to fit the DualShock 4 pad.

Sony also announced that flOw, like Flower, would soon be coming to PlayStation Vita. The same Cross-Buy promotion applies.
