March PlayStation Plus Preview

Dead Nation: Apocalypse Edition (PS4)

And, if you’re feeling really brave, take a walk down the Road of Devastation – a deadly experiment that pushes your survival skills to the absolute limit as you face hordes of zombies with no extra lives and no second chances. The dead may walk – but you can make sure they don’t walk very far.
