The challenge editor Crytek talked about adding to Ryse: Son of Rome has been canceled, Microsoft has confirmed.

“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,” a Microsoft spokesperson said in a statement to Polygon. “We look forward to sharing more details soon.”

The challenge editor was supposed to allow players to easily create challenge levels for its Gladiator mode using Microsoft’s SmartGlass app, and upload them, giving access to other players.

Ryse: Son of Rome is on sale for $40 until Feb. 24, though some users aren’t seeing the reduced price. An additional sale on the game’s DLC will begin on Feb. 25.

Microsoft and Crytek will also launch the Mars’ Chosen Pack for Ryse: Son of Rome on Feb. 28. It will be available as part of the game’s $20 season pass or as an individual download for $9 and includes new maps, a new character skin, and a new cooperative Survival Mode.
