When Ryse: Son Of Rome was being showcased last year there was mention of a challenge editor for the co-op portion of the game, one where players could create and edit the map to add new objectives. This editor would have been accessible on the Xbox SmartGlass app and once a piece had been created it could be shared with the world so others could try it out. However, that Challenge Editor is no longer a part of Ryse’s future.
“After careful consideration, we have decided to cease development on Ryse: Son of Rome’s challenge editor and focus on improving and expanding fans’ experience with the game through both free content updates and purchased add-on packs. We look forward to sharing more details soon.”
Personally I’ve not had a chance to play Ryse, though I would like to try it out. A reason hasn’t been given by either Ryse or Crytek as to why the editor was dropped, so it could be anything from not being able to implement it properly or a lack of demand.
