DevBlog: City Incidents

Working from dusk till dawn, skin tanned from the smoldering heat of molten steel, just enough time to swipe the sweat out of your eyes. The Baron demands his guns and there is no time to breathe or room for compassion. And in one misfortunate moment of exhaustion, a hand slips and the massive calciner first starts to sway, before seconds later, its scorching load burns its way through the factory.

Incidents such as blazing firestorms bring tension when managing a sprawling metropolis and they also mimic the realism of catastrophes which can throw life out of balance. You are the major in charge of the fate of your citizen, as you have to strike the balance between relentless progress and the glooming danger that one catastrophe might be enough to throw your city into chaos.

City Incidents in Anno 1800
For the seventh title in the series, we decided to expand on the city incidents from the fan favorite Anno 1404. The rule is that incidents can happen at any time while the likeliness is determined by several factors. Working conditions and happiness of your residents, as an example, affect the chance of a strike to happen while your heavy industrial districts have a higher risk of a fire breaking out. While every incident has its own chance of dying down on its own after a while, the chance of a fire spreading wildly through your streets is way more likely, especially in cramped residential districts.
You won’t be able to disable city incidents completely, as they are intertwined with different game systems, but if you like a more relaxed experience, you can turn the likeliness of them happen significantly down. Or if you like a real challenge, how about scaling them all the way up to the max?
In total, Anno 1800 will have three different types of city incidents to keep you on your toes.

Wait a moment, you said….EXPLOSIONS?!
As fire isn’t enough of a hazard, there is now a chance for some production buildings to explode. Dynamite might be the best example, but every building which makes use of heavy machinery and chemicals can literally blow up. If a production buildings explodes, it will immediately put the building in ruined state but if that wasn’t enough of a problem, burning debris fly around and might set nearby buildings on fire. There are various factors for the likeliness of an explosion to happen:

  • Type of the production (dynamite has a very high risk, Schnapps or Motor factories significantly lower)
  • Working conditions and production output (high production output raises the chance)
  • If the building is on fire (will raise the chance of explosion for these buildings significantly)

Imagine a rare chain reaction such as a schnapps facility burning down, bursting into spitting debris, sets more schnapps distilleries on fire causing a nightmarish chain reaction.

Fire: Blazing heat and explosions, what’s not to like?
Fire is not only the most traditional incident, as firestorms eating through rooftops of a densely populated cities are a primal nightmare since mankind erected the first cities.
In older Anno titles, fire could only appear and spread in residential areas but now, they will be also able to attack your production buildings, with your modern factories especially being a welcome target for the flames. To expand that system further, different production chains have a higher chance of catching fire than others, representing the brutal industrial expansion and workshops growing to enormous factories.
A factor influencing the chance of a fire appearing are the working condition slider, as pushing your workers into overworking themselves might boost your productivity but also raise the chance of an unfortunate incident happening. An increasing problem during late game, as oil production chains and the electricity feature, which can boost some production above and beyond, provide great benefits but are a real safety hazard.
While other incidents such as sickness can spread even faster than fire, the flames are way faster in shutting down buildings, which means cutting you off from taxes and workforce from the affected area.

Illness: Big city life
The chance of a sickness spreading through your cramped metropolis is affected by two elements, working conditions and pollution from nearby production buildings.
Different than fire, illness is targets only residential districts. This way, it will still affect your available workforce but you won’t need to build hospitals close to your factories.
Once a sickness breaks out, residents will stay home until they have recovered, which functions as a temporary de-buff to workforce and taxes provided.
But beware: in the overcrowded and sooth blackened cities of the 19th century, an illness can spread rather fast and you will probably never underestimate the danger of a outgrown plague ever again once it hit a large amount of your population. And if you thought your outposts or getaway islands are safe – sickness can even jump over to your or ships from other parties to spread across islands or even travel to another session.

Riots: The birth of the social movement!
The workers movement marched through the 19th century and was the most influential factor to change the society as we know it today. Riots can affect residential and production buildings of your city, although with a different reasons why people go on the streets or lay down their tools.
In residential areas, the chance of a riot is affected by the general happiness of your people while in production districts, working conditions are the biggest cause for a strike.
That means that if you overwork your people, they might stop working and go on a strike even if the folks in the residential area are happy and vice versa. It goes that far that it can even affect specific production chains as you are able to alter the working conditions for each production separately.
A strike can start small, just affecting one specific building but might erupt to a general strike which can cripple a whole type of production chain.
Strikes can further spread as people will gather together, shouting their demands and sprawling through the streets on the look for sympathizer and fellow comrades.
Don’t underestimate the frustration of the populous, when a situation goes out of control, a strike can become a grown movement including heated arguments, raising fists and Molotov cocktails.

City Institutions
Traditionally, there are ways to mitigate the situation or even to take immediate action, namely city institutions such as the fire brigade which will reduce the likeliness of a fire in their influence radius.

There are three different buildings for each incident (remember, explosions are a part of the fire incident): the fire brigade, the hospital and the police station.
The fire brigade is the first building to unlock, has a medium influence range but also don’t needs as much constructions space. You might want ensure that your residential as well as production facilities are covered by enough fire brigades or additionally boost their effect with specialists items in your city hall. The hospital has higher upkeep and construction cost, but makes up for it with a higher influence radius and a general lower chance of illness spreading compared to a fire.
To avoid strikes, you could become a man of the people or you can make sure that enough police force has a watchful eye on streets and neighborhoods. Police stations reduce the chance of a riot in residential and production areas and if things get out of hand (or you just prefer the stick rather than the carrot), you can mobilize your force to put the revolter in their place.

Keep in mind that similar to the transport of goods, the street distance affects the time a Red Cross volunteer or police cart needs to get to their place of action.

City institution have a limited amount of units which they can send out to fight the incidents. However, you can activate their ability to mobilize additional units in case of emergency: you can call happy residents into civil service, from Red Cross volunteers, neighborhood watch and civil firefighters.
Using that ability will spawn more of the specific healing unit and its cooldown is determined by the happiness of your population. Remember: Don’t count volunteers if people are too busy throwing eggs at your counterfeit, if your residents hate you, the cooldown will completely freeze.

Another interesting counter to incidents happening in your overcrowded late game metropolis and power economy are items, which you can slot in guild halls to either affect the likeliness of incidents happening in production buildings or specialists like very effective and renown police constables in your city hall to make your institutions more effective.

From riots to explosions, we build on the complexity of the incidents feature while working conditions or the use of items leave players the agency to let the benefits outweigh the risks or to minimize the chance of catastrophes to happen. What do you think of the new system and is the thrill of a full grown emergency situation part of the fun or do you prefer a more relaxed approach?

    This game has a great potential.

    That i would like to do, is create troubles and foment revolts in the others enemy’s cities. or corrupt their industries.

    That’s could be fun that players can choose an ideology, that’s could add some boosts in many ways.

    I Think the game will be perfect if we can training and send some troops on the enemies lands. The game is pretty nice for managing the economy, and trades, people. But a little bit limited on the wars and the destructions we could inflict on the competitors. maybe you’d make an addon, or patch with more features on this ??

    Thanks you for the great job thats you do

    All these incidents belong to a good game.
    It depends on my mood what “kind” of game i like to play from time to time. The possibility to set influence on the level of catastrophes makes it interesting to approach to the daily “level of emotions”. Sometimes hard with every possible fire, riot or explosion and sometimes “the laid back and enjoy game”

    1) Is it possible to reduce/increase level while playing?
    (would be nice)
    2) or are all these incidents only set at the beginning and fixed?

    Sometimes, after a long and busy day, after meetings and moments with chiefs and other alliens, i would like to press a “Monday Button” and my brave people in town are reducing everything to dust…so that we can start new and regain happiness.

    You are doing right guys. Go on.

    Hi, I prefer a more relaxed approach at an early stage of the game, on more nostrums you can be more aggressive.

  4. r ruzen_qures February 14, 2019

    I wished there are some new world incidents specific for them. Also, not adding weather to gameplay is a missed opportunity

  5. b banan1996.1996 February 14, 2019

    I really like city incidents in 1800 and that they are connected to other features such as workforce conditions and happiness.

    I just hope that riots won’t occur when my population is happy as it happened during beta a few times. My population sometimes started riots when no happiness factor was negative which in my opinion shouldn’t happen at all. When riots occur I feel like I failed to make my people happy.

    I love this game mode!
    I think that the player should have the opportunity to choose the types of disasters they want in his continuous parts: this is a key point in my opinion.
    The idea of explosions is really good.
    I will also add another type of accident that could occur (and was very present at the time): mine collapses (dust and gas mixed with oxygen from the air can become explosive and lead to significant human losses;
    miners are exposed to floods and landslides) – Conditions of work well described by Zola in “Germinal”.
    -> In the game, this accident could stop production for a while or even destroy the mine which will force the player to rebuild (+ the impact of the accident in the newspaper and on the population). Maybe it’s too precise but I think it’s representative of the time.

    Kepp up the good work! 🙂

    Would a double road between residences protect them from fire across the road? OR do we need 3? 😀

  8. p palemale53 February 13, 2019

    I enjoyed the challenge of mitigating the incidents in the recent beta.

    It is a good idea to pave the roads from your emergency buildings to help the vehicles get to the incident location sooner.

    As with paving roads in production areas, this is a realistic way of boosting effectiveness!

    Will unemployment affect the city?

    •   Bastian Thun February 13, 2019

      No, the problem with unemployment is that we would force the player to be always in a perfect balance between workforce / production. That way, it would force one very thoughtful playstyle while at the same time punishing players trying to expand to quickly or to not doing progression on a step by step basis.
