Update 36906 is a patch in Age of Empires II: Definitive Edition, released on April 29, 2020.

Game stability[]

  • Fixed various crashes which could be triggered when spectating games.
  • Fixed various one-off crashes.


  • The game client will no longer download additional localized versions of the The Art of War videos other than the selected language and English (as a backup). Excess variants have been removed, reducing the total size of the game’s installation by ~5GB.


  • Fixed an issue where HD AI could not be selected as the AI Difficulty when using any language other than English.
  • Added new hotkeys to select all Markets, all Blacksmiths, and all Universities.
  • Added a new “Dynamic Grid” option to the setting menu. This allows players to customize the shade and visual intensity of the grid that shows up in-game, as well as the circumstances under which it is displayed—such as when placing buildings, ordering ranged units, etc.
  • Fixed an issue where Organ Guns were not always classified as siege weapons, thus allowing them to be converted without the Redemption technology.
  • Recorded games no longer break as soon as a player quits, drops, crashes, or otherwise departs from a match.
  • Implemented additional tracking and safeguards to defend against cheat programs.

Chat Filtration[]

  • Updated the profanity filter to be far less restrictive of normal and contextual (i.e. Age of Empires-specific) chat.


  • The Age of Empires achievement — which requires players to win a match with every civilization — no longer requires players to also win with the “Random” civilization option.
  • The Pitched Battle achievement is now correctly awarded when players complete ‘The Field of Blood’ mission (in the Pachacuti campaign) without constructing walls.

Civilization balance[]


  • The civilization bonuses which provide additional villagers to the Chinese and Mayans and a bonus llama to the Incas have been disabled in the Empire Wars game mode.
  • Fishermen can now drop food they’ve collected at Docks.

  • Torsion Engines: Increased the width of upgraded Scorpion projectiles from 0.3 to 0.5 tiles.


  • Now receive the Loom technology as a civilization bonus.


As a civilization bonus, Fisherman now work 10% faster rather than working 15% faster and carrying +15 food.


  • Fishing Ships now correctly cost -15% wood (instead of -15 wood). This effectively raises the cost from 60 to 64 wood.


  • Reduced the work rate of Farmers by 3%.
  • Can no longer train Bombard Cannons.


  • Leitis [Standard & Elite]: Adjusted the training cost from 50 food, 80 gold to 70 food, 50 gold.

  • Harbors now (properly) receive the benefits of Chemistry, Murder Holes, and Heated Shot when Thalassocracy is researched before any of these technologies.


  • Removed the bonus to the work speed of Town Centers and Docks in the Dark Age. They now work: 10% faster → 15% faster → 20% faster


  • Boyar [Standard & Elite]: Reduced speed from 1.4 to 1.3. Increased pierce armor by +1.


  • Flaming Camels now benefit from the +5 attack vs. buildings bonus provided by an Indian ally.


  • As a civilization bonus, Barracks and Stable units now receive a +1 melee armor bonus (+2 total) in the Castle and Imperial Age.
  • Teutonic Knight: Increased speed from 0.7 to 0.8.

  • Starting villagers and herdable animals should no longer spawn on the same tile.
