IO Interactive needs a few more months to bulk out the new Hitman -- the studio has pushed the game's release date back from December 2015 to March 2016. The delay applies to all versions: PlayStation 4, Xbox One and Steam. Wherever and whenever you end up playing Hitman, it's going to be a slightly different experience for the series. IO Interactive and publisher Square Enix plan to release Hitman in chunks, starting with a large initial launch. Afterward, the game's remaining locations will be released over time. The new Hitman's tagline is, "Enter a world of assassination," which feeds into the idea of a constantly updated, evolving landscape.
