Speculation has been rife of late of a port to Ps4 of Housemarques twin stick zombie romp Dead Nation. It's now been confirmed as the Ps4's PS+ addition for March in the EU. Not much else is known about the port aside from the addition of the Road to Devastation DLC is included, so hopefully more light will be shed in time on the re-Release.
Tomb Raider & Brothers: A Tale of Two Sons are the Ps3 releases with Pixeljunk Monsters being offered for the Vita. The PS+ refresh is due around the 5th March
