Microsoft has adjusted up the price of three of its four first-party Xbox One launch games from £44.99 to £49.99.

Dead Rising 3, Forza 5 and Ryse have all been bumped up to the higher price point, which was in fact the launch price for Microsoft's other launch title Zoo Tycoon.

No reason for the hike has been given.

Despite the price increase, Microsoft's pricing remains £3 cheaper than Sony's first-party titles Killzone: Shadow Fall and Knack.
