AOE4 Patch Notes (Season 1 Update) – April 7, 2021

New Features and Highlights

  • Introducing the Age of Empires IV Content Editor (Beta)! With this powerful tool, creators are invited to embrace and create their own ideas within the game and share them with the wider community! We talk more about the Content Editor below, including providing a quick overview of the in-house-created mods launching with Season One.
  • Our first ever Ranked Season starts next week, April 13th! Prepare your best strategies and work your way through the ranks over the next several weeks.
  • Based on your feedback, we’ve implemented the Global Build Queue! The Global Build Queue is visible in both gameplay and observer modes. Using the Global Build Queue you’ll get an overview of all your upgrades and units in queue at all times in the HUD.
    • Click specific tiles within the Global Build Queue to select the building the unit or upgrade is queuing within (or the unit itself for build-on-the-field siege units) and optionally move the camera to that location based on the current “Find and Cycle Units & Buildings” setting
    • Ctrl+Click tiles in the Global Build Queue to cancel the most recently queued item in the stack
    • The Global Build Queue can be disabled or set to “Upgrades Only” in the in-game settings
    • Use hotkeys to cycle between “Show All,” “Upgrades Only,” and “Hide.” The default hotkey for this function is Ctrl+Shift+Q.
  • We know you’ve been looking for improved hotkeys, and while we still have some work underway and planned for the future, Season One includes a number of exciting changes! For a deeper in-depth look, check out the Keyboard Controls and Quality of Life section below.
    • We’ve added the ability to rebind hotkeys to Mouse 3, 4, and 5
    • Quickly toggle on or off Control Group exclusivity, or use any number of new hotkeys to add or remove a unit from a Control Group
    • You will be able to bind other commands to the “ALT” and “Shift” keys
      • We are aware that hotkeys bound to Alt, Shift or Ctrl can lose functionality after restarting the game. Our teams are working on a fix for this
    • New Global Hotkeys enable you to cycle or select all buildings of a specific type, cancel items in production queues, save camera locations, and much more
    • Additional categories have been added to the hotkey menu to improve navigation
  • It is now possible to navigate on the map after being eliminated or when the game is over in Skirmish and Multiplayer games. You can go back and forth between the map and the post-game screen using the “Continue” and “Back” buttons.
    • The Fog of War is revealed to all players when the game is over
    • There is a new “Reveal on elimination” setting for custom games, revealing the Fog of War to eliminated players
  • Introducing the Patrol Move in-game! Patrol allows units to move along a path and attack any enemies they see.

General Changes

1v1 Resource Spawn Tuning

  • 1v1 (Micro) map size resource balancing has received a pass, with the goal of improving the distribution of resources between players.
    • On open maps, like Lipany and Dry Arabia, this has meant objects like relics, gold deposits and stone deposits are now spawning in a tighter band for each player, to cut down on cases where one resource node would spawn considerably further away for one player than for the other. We are always tweaking and looking to improve this, so keep sending us screenshots and map seeds when you feel things are generated unfairly!
    • On divided maps, like Mountain Pass and Mongolian Heights, we have done additional custom tuning for several maps to help ensure that the dividing geography does not separate one player from their allotment of resource deposits. We were seeing instances of, for example, both players’ large gold deposits spawning on the same side of the mountain range on Mountain Pass. This was due to how we place resources within a central band of map area that is calculated based on pathfinding distance from each player’s TC to each point on the map. In cases like Mountain Pass, if one player spawns closer to the opening, the “midpoint” between players would be on one side of the mountain range, and our contested resources would be placed there. This set of tuning has been about finding new constraints for this banding on maps with dividing geography. Danube River, Boulder Bay, Confluence, Mountain Pass, Mongolian Heights and Nagari all received custom tuning in this regard.
  • Relics will now spawn in a more balanced configuration – one accessible relic per player, 3 centrally contested relics. This updated balance logic has been applied globally to all map sizes, and tuned specifically for several maps on the Micro (1v1) size. Additional tuning for divided maps at larger sizes will be coming in a later update. Relics have been tuned to spawn further away from each other.
  • Divided maps have had custom tuning and will spawn 1 accessible relic and 2 contested relics per “side” of the map, for a total of 6 relics. This was done to ensure that maps in which terrain gives natural ownership to one player don’t have a built-in imbalance due to the nature of spawning an odd number of contestable objects. The maps that include these relic changes are Confluence, Mountain Pass, Mongolian Heights and Nagari. Small gold and stone deposits have had their contested spawn range tightened. One contested small gold and stone will now spawn per player (up from only one overall), with less likelihood that it will be too close to a single player.
  • Sacred Sites have had their spawn parameters narrowed to help them spawn evenly across the center of the map on maps where their locations are not being specifically placed by the map script (e.g. on the hill on King of the Hill).

Specific-Map Changes


  • Mountain ranges have been shortened slightly to provide a more consistent central lake and mountain configuration.
  • Deep water fish have been removed from the side ponds and concentrated in the central lake. This was to both remove instances of unbalanced amounts of safe fish and ensure that the most valuable fish are located in a contested part of the map.
  • Relic count has been increased to spawn a base 4 relics plus one per player to better ensure fairness of distribution on maps where geography can divide the map into discrete sections
  • Resource spawning for 1v1 Micro size matches has had custom tuning done on various resource deposits. Our goal with this pass was to cut down on perceived unbalanced map generations, especially on maps where map geography can divide the map into discrete sections. Resources like gold deposits should now spawn more squarely in each player’s “side” of the map, to avoid instances where a central, contested deposit could be placed on the wrong “side” of the central geography.

Black Forest

  • The “forest-y” ness of Black Forest has been reigned in to not spawn unchoppable trees in the middle of your Town Center courtyards
  • Trade Posts on Micro and Small map sizes have been adjusted to spawn closer to the exact center of the map to help ensure more equal access
  • Spawn reliability of the second deer herd per player has been improved
  • Sacred Sites have been re-added to Black Forest. We have been watching for your feedback on this change, so thanks to everyone who gave us their thoughts on the Black Forest Sacred Sites. With the way Age IV plays, Sacred Sites provide a valuable way for you to counter a locked-in defensive strategy. While we appreciate the epic slugfests that remind us of classic Age of Empires II Black Forest gameplay, we feel like the Sacred Sites play well in the Age of Empires IV version of the map.

Added Maps


As the name implies, MegaRandom has the ability to spawn in an enormous number of different configurations. We’ve created a huge number of random parameters that MegaRandom can choose from when generating, such as whether to spawn lakes and rivers, which types of impasse to use to generate terrain (if any), whether to spawn extra amounts of some resources, whether to incorporate special terrain patterns, and much more!

Crafted Map “Valley Battle”

As an example for what a crafted map may look like when created using the Age of Empires IV Content Editor (Beta), we have added a map called “Valley Battle” to the “Crafted” maps tab. This map was created to be a balanced, mostly symmetrical map that has a bit of everything – open fields for large battles, a river with numerous crossings, small lakes to take advantage of fishing, a defensive area near players’ start locations, and resources that are exactly balanced across the two halves of the map.

Map Bug Fixes

  • Stealth ocean areas have been updated to have a different colored water tile to help make their area more visible
  • Fixed a bug where min spec trees would pop in game
  • Fixed a visual issue where shadows would appear to be “rippling” on some terrains and shadows settings
