Sid Meier's CIVILIZATION VI: Gathering Storm

On November 20, 2018 2K announced a new expansion for Civilization VI titled Civilization VI: Gathering Storm. It released on February 14, 2019. The lead designer is Ed Beach, and the lead producer is Dennis Shirk. The Art Director is Jason Johnson, who also performed this function for the Rise & Fall expansion. Anton Strenger is a designer on the project. David McDonough (co-designer of Beyond Earth) designed both of the scenarios.


Environmental Effects

Volcanoes, storms (blizzards, sand storms, tornados, hurricanes), climate change, floods, and droughts periodically strike across the map. Rise in global temperatures due to use of Coal and Oil may cause polar ice to melt and sea levels to rise, flooding or even submerging coastal tiles. Any expenditure of Coal, Oil, or to a lesser extent Uranium, which includes use in powerplants, or to build build or maintain units or railroads, will add to CO2 levels.

Disaster Intensity setting is user-selectable (for those who want more or less of these effects). There are five settings, including Minimal, Normal, Heavy, and Hyperreal. (Hopefully, the fifth setting is "none".)


"When [storm] event occurs: - One of four possible storms (blizzard, dust storm, hurricane, or tornado) spawns based upon the terrain at the storm's origin. - Storms then move across the map for two more turns, causing damage to buildings and improvements and possibly adding fertility to affected tiles. As the global temperature from greenhouse gas emission into the atmosphere, the chance that a storm will occur increases. Using cleaner sources of energy reduces the global temperature increase and this mitigates the chance of storms." - (in-game tooltip)

Each of the storms has two different sizes. Hurricanes can sink ships at sea. Dust storms and hurricanes can add to the fertility of affected tiles. All storms can damage units, though according to Ed, Russian units are immune to Blizzards.

Hurricanes are named and characterized according to severity ("Category-4" is about three hexes across, and "Category-5" is about four hexes across).


Rivers (it appears all rivers) can periodically flood. Floods can destroy or pillage improvements, damage city and walls health, damage units, pillage districts and buildings, or destroy civilian units. They can also increase the yields of flooded tiles. Dam districts can control flooding.

Floods are characterized according to severity in three levels ("Major Flood, 1000 Year Flood").


When a drought event occurs:

  • Farm, Camp, Plantation and Pasture improvements are pillaged.
  • These improvements cannot be rebuilt until the Drought ends.
  • All tiles affected by the Drought yield 1 less Food than usual.

Build an Aqueduct or Dam in your city to prevent the Food loss from Drought. Drought targets areas that are devoid of all Features. Keep some Woods, Rainforest, or Marsh near your cities to lessen the chance that Drought will strike.

Volcanic Eruptions

"Another exciting new environmental effect is the addition of volcanoes. They offer some of the same risk/reward decisions as floods, with eruptions occurring periodically. When you see the magma spilling down the side of one of these you know there’s going to be damage to adjacent tiles. However, the long term benefits are there with the yields provided by the volcanic soil left behind. We have also been able to use volcanoes to add a level of realism to our map generation. We’ve always had continents in Civilization VI, but the geology didn’t necessarily correspond to continental boundaries as you might expect. We’ve updated all that so you’ll find the Mountain ranges you expect along these continental divides, as well as Volcanoes and Geothermal Fissures. We’ve also taken the Volcanoes we already had in our Natural Wonder system and made them really powerful." - Ed Beach

  • Any features in tiles surrounding an erupting volcano may be destroyed, so you may consider harvesting them beforehand.
  • There are three levels of severity of volcanic eruptions.
  • See also: Volcano

Sea Level Rise

As CO2 levels rise and the globe warms, the sea level will gradually rise and flood designated lowland coastal tiles. Vulnerable tiles will be identified in the UI with a wave icon and a number, indicating 1-meter, 2-meter or 3-meter tiles. As sea level rises in 0.5 meter increments, each group of tiles will subsequently flood, starting with 1-meter tiles. When flooded, any districts or improvements will be pillaged and cannot be repaired until the flooding is reversed by building a Flood Barrier. When the 2-meter set floods, the 1-meter set will become permanently submerged and unrecoverable, and anything on it will be permanently destroyed. The same will continue with the 2 and 3-meter tiles. The 3-meter tiles will become permanently submerged when the 3.5 meter seal level is reached, and after that there will be no further seal level rise. City center tiles cannot flood.

Flood Barriers are relatively inexpensive before flooding starts, but they become dramatically and increasingly more expensive (often impossibly so) once flooding has started, so it is wise to build them preemptively. Sea level rise starts suddenly and proceeds quickly, with rise levels happening every ~9 turns or so on Normal speed.

Nuclear Accident

Nuclear Powerplants produce energy with no carbon emissions, but are subject to the risk of a nuclear accident. There are three levels of severity. Affected tiles will be irradiated for a number of turns. See Nuclear Powerplant.

Power and Consumable Resources

"Strategic resources play an additional role in Gathering Storm. These resources are now consumed in power plants to generate electricity for your cities. Initially you’ll be powering your most advanced buildings by burning carbon-based resources like Coal and Oil, but renewable energy sources also unlock as you progress to current-day technologies. Your choices about resource usage will directly affect the world’s temperature and can cause melting ice caps and rising sea levels." -Ed Beach

Strategic resources nodes now contribute a per-turn yield to a global stockpile of each resource type, which is consumed both by one-time costs for building units, but also by per-turn upkeep costs for later units and for resource-consuming buildings such as powerplants. Upgrading units now also costs strategic resources (where applicable) in addition to Gold. In the announcement livestream gameplay, a single Iron deposit contributed 3 units of Iron per turn to the stockpile. 20 (13 fast speed) of the applicable resource is now required to build most units, and the same amount to upgrade. Units still require that there is at least 1 of a strategic resource in the stockpile in order to heal. See an updated list of new unit resource requirements here.

The stockpile has a maximum capacity; in one shot it was 50, and in another 100, and it is increased with certain infrastructure:

  • Barracks, Stables, Armories and Military Academies increase the stockpile by +10 each.

An example of a later unit that requires resource upkeep is the Biplane, which has no up-front resource cost to build, but which consumes 1 Oil per turn.

Providing power to a city still gives production boosts to buildings that require power. There are now at least three different versions of the Powerplant which consume different resources for power (Coal, Oil, and Uranium), as well as other districts and improvements that can provide power (hydroelectric dams, wind and solar farms, and geothermal powerplants).

Diplomacy Changes: Grievances and Diplomatic Favor

The "warmongering" system has been replaced with a new system of Grievances. Each hostile act or broken promise is now remembered as a Grievance, and competing grievances are now taken into account when a third party judges whether or not to be angered by your actions. For example, if another civilization declared war on you, that act is weighed against your responses.

Grievances decay and disappear over time, but not while war is still ongoing.

Diplomatic Favor is a currency which works in opposition to Grievances. It is awarded from keeping promises, participating in Emergencies and other actions. It is a tradable currency that can also affect your influence over World Congress measures.

  • Liberating a city earns 100 Diplomatic Favor and makes that city immune to Loyalty pressure from your cities and governors.
  • You gain 1 Diplomatic Favor per turn for each City-State for which you are Suzerain.
  • You earn 1 Diplomatic Favor per turn per level of your current government.
  • You earn 1 Diplomatic Favor per turn for each alliance that you have.

World Congress

"Make your voice heard among the other leaders of the world. Earn Diplomatic Favor through Alliances, influencing city-states, competing in World Games, and more. Use Diplomatic Favor to extract promises from other leaders, vote on Resolutions, call a Special Session to address an emergency, and increase the weight of your votes in your quest to achieve the new Diplomatic Victory."

  • Emergency system merged with World Congress Special Session; emergencies now voted on (including new disaster relief emergencies).
  • Each civilization has one vote, but votes can be influenced by Diplomatic Favor.
  • Available early in the game.
  • UI shows timer to next regular meeting.


Rather than a "yes" or "no", resolutions have two different effects to choose from.

  • World Religion: +10 Religious Combat Strength for this religion, or All players may condemn units of the chosen Religion, and doing so grants 25 Diplomatic Favor
  • Luxury Policy: Ban luxury, or gain additional Amenities from duplicates of this luxury
  • Migration Treaty: +20% population growth and -5 Loyalty to a civilization, or +5 Loyalty and -20% growth
  • Heritage Organization: Double Tourism or eliminate Tourism from a type of Great Works
  • Diplomatic Victory: Target leader gains 2 Diplomatic Victory Points, or loses 1 Diplomatic Victory Point. 10 points are required for a Diplomatic Victory.
  • Arms Control: All players have their Weapons of Mass Destruction set equal to the target player's, or the target player loses all of their Weapons of Mass Destruction.

The colony starship only has one component, but additional infrastructure can be built after launch (Terrestrial and Langrange Laser stations) to speed it up.

New Scenarios

The Black Death

"The Black Death ravaged Europe and western Asia in the mid-14thcentury, killing a greater share of the population than any other event in world history. The pandemic killed millions, ruined economies, upended political dynasties and transformed the face of the Western world. Your task is to lead your nation through the calamity: keep your population alive, your economy strong, and your faith unshaken amidst a world of terror and desperation."

Notes: There are four new units specific to this scenario: the Plague Doctor, Flagellant, Scholar, and Teutonic Knight.

War Machine

"At the outset of WWI, the German Imperial Army had a daring plan: invade neutral Belgium and then rush the French heartland before they could mobilize to resist. If successful, the German forces would capture Paris within a month and end their resistance forever. In counter, the French command prepared Plan 17, an all-out onslaught designed to meet and stop a German offensive. When war was declared, both armies swung into motion and set up one of the most incredible and shocking military campaigns in world history. In this scenario, players take the side of one of these two great powers at this same precipice. As Germany, your task is to capture Paris. As France, your task is to prevent its capture. The clock is ticking, and the enemy is moving. Advance!"

Notes: This is a multiplayer-only scenario. All the units I've seen for this scenario are standard game units.

Other Features

  • Improved Gameplay Systems: The Espionage system has been enhanced with new options, the Culture and Science Victories have been updated, new Historic Moments have been added, and additional improvements have been made to other existing systems.
  • Alternate civilization "jerseys": each civilization has a number of alternate two-color sets for use as alternate colors when another civilization in that game (notably the player's) is too similar.
  • On-Map Labels: Names for rivers, volcanoes, deserts, mountain ranges, national parks, and natural wonders
  • UI Improvements: Build queue, build manager, Hall of Fame return
  • Unit appearance upgrades: more ethnic/regional customizations and more prominent teamcolors

Plague Doctor

Movement: 2; Base Cost: 75 production; Maintenance: 1 Gold
"Civilian unit that can shorten the plague's duration on plague-stricken tiles and restore Loyalty to cities. Plague Doctors can be used 2 times. This can be increased with the Studia Generalia policy."
Notes: This is a special unit for the Black Death scenario. It can spend charges either on "Minister to the Sick", which reduces the duration of plague on the tile by 50%, or on "Pacify City", which adds 20 Loyalty to a city.


"Civilian unit that can gain Faith, Culture and Loyalty from plague-stricken cities."
Notes: You are given the choice to unlock either the Flagellant or the Scholar; you can't have both. The "Purge Sins" ability, used in a plague-stricken city center, generates 50 Faith, 10 Culture, and adds 30 Loyalty to the city. The Flagellant is consumed by this action.


"Civilian unit that can study plague-stricken cities to gain Science. Scholars can be used 2 times. This can be increased with the Studia Generalia policy."

Teutonic Knight

Movement: 2; Combat Strength: 38; Base Cost: 100 Production
"Holy Roman Empire unique unit that replaces Swordsman. No Gold maintenance. +8 Combat Strength when fighting in enemy territory."


Notes: The Builder has a special medieval graphic for this scenario.

Changes to Existing Units

Unique Units can now require Strategic Resources, where applicable. Anti-cavalry, Recon, Support and Ranged units do not require strategic resources. The normal cost for building an early-game unit is 20 strategic resources (13 on fast game speed).

New Districts and Buildings

According to the initial press release, Gathering Storm adds 5 new districts (two of which are civ unique) and 9 new buildings (4 of which are civ unique).


Requires: Buttress (new technology)
Base Cost: 81 Production
Yield: +4 Housing, +2 Amenities
"A district built on a Floodplains tile to improve the comfort of living along this river. Prevents damage from flooding of this river. Prevents Food loss during Drought. Only one may be built along each river's floodplain (whichever player completes one first) and the river must traverse at least two sides of the Dam hex."

"Finishing a Dam in a city is great: it provides the city with a nice reservoir that boosts your Housing and Amenities. (Later in the game you can add a hydroelectric station to your Dam to generate clean electricity as part of the Power system added with Gathering Storm.)" - Ed Beach

Notes: Provides flood control and fresh water, as well as Housing and Amenities. Later Hydroelectric Dam building available with Electricity. (As several observers have noted, the dam graphic was curving in the wrong direction, but this was fixed as of the 13-Dec livestream.)

  • Since a Dam prevents floods, it will also prevent improvement of flood plains tiles, so you may want to wait until after several floods to build a Dam.
  • Pillaging a Dam causes the river to flood.
  • There is a new espionage mission to pillage a Dam.
  • Military Engineers can use their charges to add 20% to the construction of a Dam

Hydroelectric Dam

Base Cost: 580 Production; Maintenance: 1 Gold
Requires: Electricity, Dam
Yield: +6 Power
Notes: A building for the Dam district that generates power.


Requires: Steam Power
Base Cost: 81 Production
"A district build on flat land to connect two bodies of water or a body of water to a City Center. Canals may either to straight through the hex or bend by 60 degrees. However three-way Canal junctures are not allowed.

"...the Canal district ... is something we’ve seen asked for again and again, and we are excited to bring it to fruition in this expansion. There are actually three parts to this. First, we have taken our player’s existing use of cities on one-tile wide isthmuses (what our fans call “canal cities”) and officially recognized these features with the art on the map (which shows a navigable channel through these cities). The second part is the introduction of the Canal district. It’s another tile that provides navigation and since it can connect into cities you can actually use two of them around a city center to create a 3-tile wide path between bodies of water. But why stop there? Here on the Civilization VI team we have heard about “a man, a plan, a canal, Panama” so we felt it was pretty imperative to have a Panama Canal wonder. There’s an achievement in Gathering Storm for creating a full 7-tile navigable path using Canal districts, cities, and this wonder together." - Ed Beach

  • Unlocked with Steam Power.
  • Must be on flat land adjacent to city center and water, and must connect two bodies of water.
  • Can build more than 1 canal per city, but cannot connect to another canal (except the Panama Canal Wonder).
  • Can only extend 1 tile from the city center.
  • No 3-way connections.
  • Military Engineers can use their charges to add 20% to the construction of a Canal.

Industrial Zone Changes

There are now at least three types of Power Plant (Coal, Oil, and Nuclear). Each new technology adds a Conversion project to let you convert from one type of power plant to another. Modern buildings that require power will have their yields roughly halved if they are not fully powered.

Coal Power Plant

Requires: Industrialization, Factory
Base Cost: 300 Production; Maintenance: 3 Gold
Yield: +1 Production, +1 Citizen Slot, +1 Great Engineer point per turn
"Automatically converts any amount of Coal into Power for cities within 6 tiles that need it each turn, at the rate of 1 Coal -> 4 Power, Heavy CO2 into the atmosphere. The Production bonus is extended to all City Centers within 6 tiles. It applies once to a city, and multiple copies of this building with 6 tiles of a City Center do not provide additional bonuses."

Oil Power Plant

Requires: Electricity, Factory
Base Cost: 450 Production; Maintenance: 3 Gold
Yield: +2 Production, +1 Citizen Slot, +1 Great Engineer point per turn
"Automatically converts any amount of Oil into Power for cities within 6 tiles than need it each turn, at the rate of 1 Oil -> 4 Power, Moderate CO2 into the atmosphere. The Production bonus is extended to all City Centers within 6 tiles. It applies once to a city, and multiple copies of this building with 6 tiles of a City Center do not provide additional bonuses."
Convert to Oil Power Project: Bas Cost 300 Production
Notes: Graphically, the Oil plant looks very similar to the Coal plant, making them a bit hard to distinguish by sight.


Nuclear Power Plant

Requires: Nuclear Fission, Factory
"Automatically converts any amount of Uranium into Power for cities within 6 tiles that need it each turn, at the rate of 1 Uranium -> 4 Power, Miniscule CO2 into the atmosphere. The Production bonus is extended to all City Centers within 6 tiles. It applies once to a city, and multiple copies of this building with 6 tiles of a City Center do not provide additional bonuses."
Convert to Nuclear Power Project: Bas Cost 400 Production
Notes: Produces "miniscule" carbon emissions, but comes with the risk of a nuclear accident. The risk increases as the power plant ages. This risk can be mitigated by periodically using the Recommission Reactor project, which resets the "accident timer." The graphic is the same as the current generic power plant.

New Entertainment Complex Buildings

Thermal Bath

Base Cost: 445 Production; Maintenance: 2 Gold
Yield: +2 Production, +2 Amenities from entertainment
Requires: Arena, Entertainment Complex
Notes: Unique building for Hungary; replaces Zoo. Thermal Baths provide +2 Amenities and +2 Production to every City Center within its 6 tiles. These bonuses apply once to a city, and multiple copies of this building within 6 tiles of a city do not provide additional bonuses. If there is a Geothermal Fissure within the same City’s borders, the Thermal Bath provides +2 Amenities and +3 Tourism.

New Theater Square Buildings


Requires: Theater Square
Notes: Unique building for Maori; replaces Amphitheater. Yields +2 Culture and Faith to all of this city's tiles with a passable feature. After Flight is researched receive +2 Tourism to all of this city's tiles with a feature. Costs no maintenance. Has no Great Work slots.

New Government Plaza Buildings

Queen's Bibliotheque

Base Cost: 217 Production; Maintenance: 2 Gold
"A building unique to Sweden. This building provides 2 slots [each] of Writing, Music and any type of Art. Awards +1 Governor Title. Unlocks the Mercantile Legacy Policy Card."
Yield: +2 Great Artist, Great Writer, and Great Musician points per turn
Notes: Tier 2 unique Government Plaza building for Sweden. Note that because of Kristina's unique ability, if all 6 slots are filled it is automatically themed.

New Commercial Hub Buildings

Grand Bazaar

Requires: Commercial Hub, Market
Base Cost: 220 Production
"A building unique to the Ottomans. Accumulate 1 extra Strategic resource for every different type of Strategic resource this city has improved. Receive +1 Luxury for every Luxury resource this city has improved."

Base Cost: 27 Production
Yield: +1 Great Admiral point per turn; +1 Gold from every 2 adjacent district tiles. +1 Gold from each adjacent coastal resource tile. +2 Gold from each adjacent City Center tile. +1 Gold from each Government Plaza tile.
Citizen Yields: +2 Gold, +1 Science
"A district unique to Phoenicia for naval activity in your city. Replaces the Harbor district and cheaper to build. Must be built on Coast or Lake terrain adjacent to land. +50% production towards naval units and Settlers in this city. All wounded naval units in this city's borders heal +100 HP each turn.
Notes: Adds +2 Gold to adjacent Commercial Hub, according to the tooltip for the Commercial Hub.

New City Center Buildings

Flood Barrier

Requires: Computers, one or more Coastal Lowland tiles.
Base Cost: 100 production; Maintenance: 1 Gold
"Protects Coastal Lowland tiles in this city from flooding. Initial build cost and per turn maintenance are variable based on the number of Coastal Lowlands in this city and the current sea level. If constructed after some of a city's tiles have been flooded, those tiles can be repaired in full. Submerged tiles however are never recoverable.  Will not be pillaged if the city is captured."
Notes: This is a building, technically built in the City Center district, even though the graphic appears on the coast. Maintenance cost increases as sea levels rise.

Changes to Existing Buildings

  • All Walls now provide +100 Outer Defense.
  • Aqueduct now also provides +1 Amenity if adjacent to a Geothermal Fissure, and prevents Food loss during a Drought.
  • Research Lab has a Power Load of 3 and yields +5 additional Science when Powered
  • Broadcast Center has a Power Load of 3 and yields +4 additional Culture when Powered
  • Barracks, Stable, Armory and Military Academy each add +10 to the Strategic Resource Stockpile
  • Shipyard now yields an additional +1 Food and +2 Production.

New Wonders

According to the initial press release, Gathering Storm adds 7 new World Wonders.

Golden Gate Bridge

Requires: Combustion; Cannot be built on a lake; Must be build on coast.
Base Cost: 1620 Production
"Land units can cross without needing to embark. Acts as Modern Road and creates Modern Roads (if not present) in land tiles on either end. City gains +3 Amenities.

The bridge must run straight across the hex between two land tiles directly opposite each other. At least one water tile must be present on both the left and right sides of the bridge."

Panama Canal

Requires: Steam Power
Base cost: 920 Production
"Upon completion 1 or 2 adjacent Canal districts are automatically constructed. The Canal wonder tile can now be crossed by naval units. Must be built on a flat land tile where there are two adjacent tiles directly across the build tile from one another that meet the following criteria: one adjacent tile must be able to legally hold a Canal district connecting into the Panama Canal construction tile; the other must be either a city, a water tile, or be another tile that can hold a connecting Canal."
Notes: Provides extra gold for Trade Routes that cross it.

Notes: Meenakshi is a Dravidian temple complex in Madurai in southern India devoted to Meenakshi, a form of Parvati (consort of Shiva).

Changes to Existing Wonders

  • Statue of Liberty now awards +1 Diplomatic Victory point when built instead of 2 Settlers.
  • Jebel Barkal now provides +4 Iron per turn instead of 2 Iron.

New Improvements

According to the initial press release, Gathering Storm adds 15 new tile improvements, of which 4 are civ unique.

Mountain Tunnel

Requires: Chemistry
"Acts as a movement portal on a mountain range, allowing units to move into it and exit from another portal at the cost of 2 Movement. Can only be built on an adjacent Mountain tile. Cannot be pillaged or removed.
Notes: Created by the Military Engineer.


Requires: Steam
Notes: Railroads can be built by Military Engineers. Trade Routes that follow railroads earn additional Gold. Railroads do not cost Build charges, but each tile costs 1 Iron and 1 Coal. This Coal expenditure does contribute to atmospheric CO2.

Nazca Line

"Nazca Lines provide +1 Faith to adjacent tiles, +1 Faith to adjacent tiles with a resource.  +1 Food to adjacent Desert and Desert Hill tiles after discovering Civil Service. +1 Production to adjacent flat tiles after researching Mass Production. +1 Appeal. Can only be built on flat Desert. This tile cannot be worked."
Notes: Buildable by the Suzerain of Nazca.


"Moai provide +1 Culture, +1 Culture for every 2 adjacent Moai, +2 Culture if on or adjacent to a Volcanic Soil tile. +1 Culture if on or adjacent to a Coast or Lake tile. Additional Culture and Tourism as you advance through the Civics and Technology tree. Can be built on Plains, Plains Hills, Grassland, Grassland Hills, or Volcanic Soil. Cannot be placed adjacent to a Woods or Rainforest tile."

Open-Air Museum

"Provides +2 Loyalty per turn in this city. +2 Culture and +2 Tourism for each type of terrain (Snow, Tundra, Desert, Plains or Grassland) in which at least one Swedish city is founded. One per city. Tiles with Open-Air Museums cannot be swapped."
Notes: Unique improvement for Sweden.

New Terrain Features

Floodplains are now dynamic, with variable fertility depending on flood activity. Volcanic soil probably has a similar variable mechanic. Some terrain features are now named and the name is displayed on the map.

"Every time a new feature – river, volcano, mountain range, or desert – is discovered, it is named after the discovering civ." - Ed Beach.


Notes: A volcano can be dormant or active, the latter of which is more likely to erupt. Eruptions are destructive (they can damage structures and will wipe out any features or resources in affected tiles) but can enrich surrounding soil. Volcanoes count as a feature on top of a Mountain, so all mountain properties apply.


Volcanic Soil

Notes: Volcanic Soil is deposited around a volcano when it erupts.

Geothermal Fissure

Yield: +1 Science
Notes: Can be improved with a Geothermal Power Plant. Adds +1 Amenities to adjacent Aqueduct districts (heating baths).

New Resources

Strategic resources now give a per-turn yield towards a stockpile, which is consumed by building new units and by per-turn upkeep of later units and some structures (like coal and oil powerplants).

New Natural Wonders

According to the initial press release, Gathering Storm adds 7 new Natural Wonders. The yield bonuses for existing volcanic natural wonder tiles have now been mostly transferred to the Volcanic Soil tiles around them.

"We’ve also taken the Volcanoes we already had in our Natural Wonder system and made them really powerful." - Ed Beach

Mt. Vesuvius

"One tile impassable natural wonder. It appears as a Volcano and provides +1 Production to adjacent tiles. On eruption it gives high yields to adjacent tiles, but large Population loss. It is always active."
Notes: The code nabuildethe expansion during development was "Vesuvius."

Sahara El Beydar

Notes: This is a standing stone feature in the desert near Farafra, Egypt. Appears to be a four-tile natural wonder that yields +4 Gold, +1 Science and +1 Culture.


Each tile adds +2 Gold to adjacent Commerci "Two tile impassable natural wonder. +1 Amenity. It provides an additional Amenity if adjacent to an Entertainment Complex. Major adjacency bonus to Theater Square, Campus and Commerical Hub districts. Standard adjacency bonus to the Holy Site distrit. It provides Fresh Water."
Notes: a geothermal feature in Turkey.


"One tile impassable natural wonder. +50% Production when producing Wonders and districts in adjacent tiles. It provides Fresh Water."
Notes: A cenote (a natural limestone sinkhole) in the Yucatan, Mexico.

Chocolate Hills

"Four tile natural wonder. It provides +1 Food, +2 Production, and +1 Science."
Notes: A geological feature of the Philippines.

Mato Tipila

"One tile impassable natural wonder. Provides +1 Faith and +1 Production to adjacent tiles."
Notes: A.k.a. "Devils' Tower," the iconic Wyoming landmark made famous in Close Encounters of the Third Kind.


Yield: +3 Culture and +1 Production
Note: "Mud volcanoes" in Azerbaijan.

(Icelandic Volcano The Name of Which Ed Beach Won't Even Try To Pronounce)

Notes: I thought that Ed might mean Eyjafjallajökull, but that is an existing natural wonder, introduced in the Viking DLC. This volcano has the same two-hex layout, but doesn't look exactly the same, so it's not clear whether this is new natural wonder or a revamp of an existing one. If the latter, it probably doesn't count as one of the 7 new natural wonders in the expansion.

Miscellaneous Changes

  • New Spy promotions (Counter-espionage) and missions (Breach Dam).
  • Trade Routes now earn increased Gold if a large percentage of the route is over water, canals, railroads, or mountain tunnels.
