The Winter biome will be available in-game starting today (December 6th) and will be available in skirmish and custom lobbies until a planned patch in early 2024. 

Stability Fixes

A number of compounding events led to server issues reported on November 18th and 19th. Since then, we’ve taken several steps to improve server latency and stability, including the previously communicated server maintenance windows on November 23rd and 29th. This patch also includes some game-side fixes meant to act in tandem with improvements already made to the server. Thank you all for the reports during this time.  

Map Adjustments

Our most recent major update introduced 3 new maps, while our expansion added an additional 10. Several balance changes and bug fixes have been made to some of these and existing maps, detailed in Maps section further on. 


Several players have noted that some of the translations in our expansion were inconsistent with the quality of localization for Age of Empires IV. Thanks to community reporting, we have identified some of these mistranslations and today’s patch fixes many of them, especially with our Chinese localizations. 

We welcome further input and discussion on the Age Forums, where our community heroes have already been hard at work. Thank you! 

New Official Mod: Free Camera 

By popular request, we are introducing a new official mod to allow creators to freely move the camera for taking videos and screenshots. The “Free Camera” mod unlocks the camera from its default constraints and allows movement around without limit. 

Balance Changes

With the introduction of 2 new civilizations and 4 variant civilizations, most of today’s balance changes are focused on the impact these new additions have had on recent gameplay and as such there are more balance changes than typical for our minor patches. You can read more about these in the Civilization-Specific Changes section below.

Known Issues

Ayyubid House of Wisdom does not allow for additional Wings when starting in Age 2 or Later
We are aware of an issue that impacts the Ayyubid’s House of Wisdom when starting the game in the Feudal Age (II), Castle Age (III), or Imperial Age (IV). When starting in these ages, the House of Wisdom does not account for any skipped ages and allow additional Wings to be built (like it does with its parent civilization, the Abbasid). We are tracking this issue and do not require any additional reports of this issue.

Crash on Canal Map when using unequal Team sizes
We are aware of a crash that occurs when loading into a match on the Canal map when team sizes are unequal (2v1, 3v2, etc). We are tracking this issue and do not require any further reports. Thank you.
