Dead Nation: Apocalypse Edition has been listed on PS4 as part of the March PlayStation Plus update by the Asian PlayStation Blog.
News of the game coming to PS Plus was rumoured last week, so it seems like that rumour has turned out to be true.
This comes as a real surprise for PS4 owners as the game has never actually been announced for the system. Other games rumoured for PS Plus this month include Tomb Raider and Brothers: A Tale of Two Sons (PS3), as well as Pixeljunk Monsters Ultimate HD and Smart As (PS Vita).
Sounds like a decent update to us.
