A PS4 version of Shadow of the Colossus has been revealed, and will arrive in 2018.
Announced during Sony's E3 press conference, the game is the second re-release for the 2005 classic. It's unclear whether this is a remaster or a remake at time of writing. It's available for preorder now.
An HD remaster of the game was released for PlayStation 3 in 2011 - this PS4 version has been handled by the same studio, Bluepoint.
