BY 2K Mike



Hi, Civilization fans!

The first major update for Civilization VI: Gathering Storm is now live. Here's a full breakdown of what's included:



  • [ALL GAME VERSIONS] New and improved version of Map Pins (now called Map Tacks) that includes pin icons for many new specific markers (Districts, etc.), in addition to a new grouped scrollable list of pins that were placed. Thanks to Bradd Szonye for his Mod inclusion!
  • [ALL GAME VERSIONS] Map text search: Located on the mini-map tool bar. Players can now search for map items via text search and have them highlight on the map. For example, type "Iron," or "Knight." Includes search history, search suggestions, and "go to" buttons.



  • Canada: Receives +1 Production from Snow and Tundra (Including hills).
  • China: Great Wall can only be pillaged (never removed) by natural disasters. +2 Gold for improvement itself. Add +1 Gold and +1 Culture to that received for each adjacent Great Wall.
  • Egypt: Update the Egyptian Chariot Archer to not replace the Heavy Chariot.
  • Egypt: Sphinx now provides +1 Culture if built on Flood Plains. Cannot be built on Snow, Snow Hills, Tundra, or Tundra Hills.  +2 Appeal (since they are encouraged to build on Flood Plains). Cannot be built next to another Sphinx.
  • France: Château now provides 1 Culture for each adjacent wonder. 1 Gold for each adjacent Luxury Resource.
  • Hungary: Mathias ability now only 75% resource and Gold discount to upgrading levied units (instead of 100%).
  • India: Cities gain an Amenity for every Religion with at least 1 Follower. Missionaries have +2 spreads. +100% Religious pressure from your Trade Routes.
  • India: Varu ability no longer stacks but maintenance reduced to 2.
  • Mali: Nerf the Mali + City-State + Democracy Combo/Exploit. Democracy is now a 15% discount on purchases with Gold.
  • Mali: Increase Mali desert weighting.
  • Maori: Toa ability no longer stacks, and Strength is reduced to 36.
  • Maori: Reduce the Marae ability to +1 of each bonus yield, instead of +2.
  • Netherlands: Add a Production bonus towards Flood Barriers and Dams.
  • Norway: Allow Norway (only) to receive Science and Culture from pillaging improvements in addition to Gold or Faith.
  • Spain: Mission: +2 Faith; +1 Food, and +1 Production if on different continent than your capital. +1 Science for every adjacent Campus and Holy Site.
  • [ALL GAME VERSIONS] Improve leader victory preference weighting.

Environment Systems and Climate Change

  • Reduce Dust storm yields by 33%. Add some Food yields from Blizzards. Reduce damage to population and structures from Blizzards by about a third.
  • Detach climate change progress from Natural Disaster Intensity slider.
  • Move percentage of coastal tiles that can flood from 35% to 45%.
  • Halve carbon emissions from units to slow down climate change to just over half the previous rate.
  • Reduce unit CO2 emissions for a player by 50% if they research Advanced Power Cells.
  • Increased chance of Storms and Droughts per degree of temperature rise is no longer 20% for all events. Now it does not increase chance of weaker type of each storm/drought at all but instead boosts stronger type by 50%.
  • From Phase IV on Floods and Storms will not add fertility.
  • At Phases V and above yields previously added to the map can be stripped off as Storms and Droughts pass over (chances increase as you move to later phases).
  • Allow a single player's CO2 footprint to go negative (if they have run the Carbon Recapture project but never generated much carbon). Hence one player can clean up the other players' mess.


World Congress

  • Provide a one-time cap on each player receiving Favor for reviving each other major player.
  • Adding tooltip to tiebreaker scenarios so players can understand why a player won a tiebreaker.
  • Adding Favor Per Turn and Request for Aid score penalties for excessive Grievances and CO2 emissions.
  • Climate Accords competition now enables projects for decommissioning Power Plants.
  • Reducing the lockout timer on hostile emergencies so that they can show up slightly more often.
  • Reduce time between deals during Request for Aid emergencies so AI can give multiple gifts if desired.

Districts/District Buildings

  • Reducing power of Royal Society Government District Building (reducing percentage-per-builder-charge from 3 to 2).
  • Nuclear Accidents of any severity will now always pillage the Nuclear Power Plant.


  • [ALL GAME VERSIONS] Convert Science and Culture from pillaging improvements to Gold or Faith.
  • Reduce effectiveness of Raid and Total War policies so they are only +50% instead of +100% to pillaging
  • Dam districts now provides healing if plundered.
  • Pillaged Reactors cannot trigger a nuclear accident. Completing the 'Recommission Nuclear Reactor' project will also 'un-pillage' it.


  • Seastead: Cannot be placed adjacent to another Seastead.

  • Mahabodi Temple and Statue of Liberty now award Diplomatic victory points.



  • Increase the cost of upgrading units (about 33%).

  • Setup: For advanced starts, add extra Faith and scale it.
  • [XP1, XP2] Track barbarian camp placement throughout the game (much like we do storms & droughts) and shy away from camp locations that are close to previously used spots. Should distribute camps across the continents better.

  • Staging Room countdowns should reset when a new session is joined. Countdowns should persist even if the screen is simply hidden, which happens if the Game Settings tab is pressed.
  • In-game chat panel should not display dead players.
  • Additional general bug fixes and polish.


  • You can now play the Black Death scenario in hotseat/PlayByCloud. 


  • Add secondary color to jersey selection color collision detection. Now jerseys are only considered to have collided if BOTH primary color and secondary color collide. Jerseys with similar or identical primary colors are now allowed if the secondary colors are very different

  • AI will not pay for banned resources
  • Reduce the chance that the AI offers only a single strategic resource in a trade deal unless they are padding out a larger deal.
  • Improvements to AI Deal management with Gold.
  • [XP1, XP2] Fix an issue where AI was overvaluing Great Works on the turn they are created (causing lots of trade requests).

  • Improve victory strategies, including Diplomatic victory.


  • Improve AI ability to successfully complete the capture of a city during a Military Emergency they are taking part in.

Many fixes to code that controls what is expelled during city flips, capture, trade, etc.

  • If the city is flipped to a new culture, default placement rules apply, no units are booted out, except stationed air-units, unless they can't be in the new owner's territory.

  • Correct some visualization issues with air-unit rebasing.
  • When a tile is annexed by a player and it is trying to kick out any other players that shouldn't be there, don't assume that all the air units can't be there, they might be able to stay.

World Congress

  • Fixing multiple World Congress issues that could cause mis-matched or blank proposal choices to show up on the review and results screens.
  • Adding in filtering for the Migration Treaty, so that players cannot target unmet players.

  • District modifiers should now properly reattach when the district was pillaged but has been successfully repaired (was staying inactive; ex. a pillaged Suguba district that was then repaired).
  • Districts that are over strategic resources are now correctly represented in the Reports screen. Resources are shown as from that city as opposed to 'Gameplay Bonuses'.


  • Hall of Fame: Improved performance of aggregate updates. Also fixed a crash that would occur if one of the Hall of Fame aggregate queries was bad (typically from a mod).
  • Map Gen: Make is so that there is a chance that Zhangye Danxia and Mount Roraima can appear. Before there was 0% chance of them showing up.

  • [ALL GAME VERSIONS] Espionage: Fix espionage funds being siphoned not showing for negative amounts
  • City-States: When sending your first real Envoy to a city-state, but you already have Amani in that city-state giving you "virtual" Envoys there, correctly award a second bonus Envoy from the Diplomatic League policy



  • Multiple crash fixes as reported by the public crash reporting system


  • [ALL GAME VERSIONS] Re-enable SHIFT+ENTER to force end turn. Make sure that production overflow is lost if this is used.
  • Coastal Raids can no longer target Impassable plots. In Gathering Storm, this loophole allowed naval units to raid a mountain improvement (ex. Mountain Tunnel) without actually pillaging it, allowing continuous gold.
  • Great Generals that transform a military unit into a Corps or Army can no longer do so for the GDR, which is not allowed to be a Corps or Army.
  • Correct exploit where player could receive duplicate Luxuries by trading it away, removing the improvement, then rebuilding it for a duplicate copy.
