April 1-15th on Xbox one is The Walking Dead: Season 2 which is an excellent game with a meaningful storyline (see my review here).
While Xbox 360 owners can enjoy Darksiders – a great Zelda-like adventure in which the player is War, the first horseman of the apocalypse.
For the rest of the month there is Ryse (available from the 1st) on Xbox One, a good launch game, if a little shallow. And Assassins Creed Revelations a solid entry into the extremely popular franchise.
Overall it’s a damn good month!
