The information was tested with multiple runs on Extreme difficulty until perfection was achieved. Unlike the "wiki guides" provided by others, safe passage with no deaths is guaranteed for all storms!

Surviving is just the bare minimum but conquering is on the elite level!

I enjoy helping others by writing about technical topics to a higher standard and provide key findings for a higher chance of success!

The guide is for everyone, but much friendlier to new players. Everything will be explained to be on the same level as those who are the most experienced. The writing will be easy to follow with plenty of screenshots for those who are too lazy to read everything!

The guide below is very strongly recommended to be read first, before continuing.

The city design is based exactly off of that guide and fully elaborates the intricate game mechanics and designs!

The guide is structured to explain all important events and daily tasks in chronological order.

For convenience, the table at the very top is a short summary of important tasks of the day and time stamps of emergency shifts.

Please remember to read every detail carefully to make the most out of the guide!

Each save needs to have a detailed title that includes the Day # and time. Frequency of saves should be at least 4 per day for each period (e.g. Morning 6:00-8:00, Noon 12:00-16:00, Evening 18:00-20:00, Night 20:00+).

In addition, 2-3 additional saves separated by few hours are needed to deal with random adverse events and using Emergency Shifts.

The best map to select is the Crater and set all conditions to extreme while turning off Random Hazards (unnecessary suffering) for UltraMarathon Extreme Achievement!

Note: On Extreme, Hunger & Sickness problems will develop rapidly in 24 hours if ignored.

The best conditions to roll for are:

• A starting temperature of -20C with -40C forecast on 4th day to avoid too much sickness early on.
  
• Iron and Coal Deposits being clumped together (see below) to use fewer Steam Hubs.

Two coal deposits lumped together.

Two iron deposits together with the third coal deposit.

Order is favored over New Faith because of more discontent reductions and Foreman for major production boosts beyond 100%. The Guard Tower serve as both Fighting Arena and House of Prayer to give double benefits.

Pause the game immediately to sign the first law and show the people who the Boss is!


Delete the small street on the 2nd ring that is in front of the Stockpiles to get 2 extra wood.
Build the 2 Workshops further away on the 3rd ring with the extra wood used for the longer street.
Employ everyone on wood crates with the remaining 5 engineers on steel. They will build the Workshops first before working.

Once the first Workshop is complete, activate Emergency Shift and transfer 5 engineers from Steel Wreckage to begin Sawmill research. Transfer the next 5 engineers from Wood Crates to the second Workshop without the Emergency Shift.

At 16:00, activate another Emergency Shift on Wood Crates that is in a cluster of 2 resources.

Before 18:00, place 2 Gathering Posts and 1 Med Tent beforehand to save time as workers near the vicinity will immediately construct them afterwards. The two designated locations were selected because of the steel resources.

FYI, Gathering Posts are best used on resources that were never worked on and have more than 2-3 resources within its range.

Build streets to the Gathering Post from the Med Tent. Notice how the street is angled a bit to not interfere with home building and was built later.

Around this time, the housing quest will display as a question mark on the generator and expires exactly at 22:00. Wait until the very last second for more time before agreeing to get homes for everyone. Do not let this notification pass or suffer a discontent penalty!

At this time, start with 2-3 tents then build a 4th one after the 2 Sawmills.


Use the temporary tent as a template to build the correct street, then delete after. Can build most of it first before actually building the saw mills.


Before midnight, employ the Med Tent to prevent Engineers from getting sick. Employ both the Sawmills and Gathering Posts from crates, except the Emergency one (can be moved at 06:00).


Around 23:00, turn on there generator with overdrive to have less sick people and takes roughly 2/3 of a hour to heat up.

Adjust all workplaces to have extended hours after signing.

Sleep caps construction to ~8 buildings. Sawmills and Gathering Posts need to be built first before the Tents. Otherwise, redo with earlier save.

The temperature has not dropped and generator can be shut off at 06:00 to save coal.


To bypass overworked deaths from Emergency Shift, refer to the Perfect City Management guide above.

Build the Beacon, Cookhouse, 2nd Med Tent, 3rd Saw Mill, and finish Housing quest.


Notice a temporary street to squish in the Cookhouse on 5th ring.


Second Med Tent in 1st ring.


Build Sawmill near Beacon.


Create Scouts out of the ill to be healed later and send them away.

At 15:00, transferred workers from crates to steel debris. Toggle new workplaces to extended hours.

At 23:00, turn on generator with overdrive to reduce sickness before sleep time. There will be no future reminders about this.

The temperature is tolerable and the generator can be be shut down at 06:00.


Partially staff the medical tents to transfer engineers to the 2nd workshop.

At 15:00, build 2 Hothouses (only finish one) with the spare workers from Gathering Post after swapping them with children from the Cookhouse. Employ the Hothouse for some food.


Build 6 tents for future survivors.

Temperature dropped to -40 C and the generator needs to be kept on.


If event with child injured, do not give day off. Created 2nd scouts from healthy people this time.

Build Gathering Depot and more tents.


Scouts found their first Survivors that the city desperately needs and allow them to be escorted back for this one time only.

Temperature is still frigid for the day and the generator needs to be kept on.


Build Watchtowers first to complete quest. then Guard Towers.


Refer to Perfect City Management guide above for detailed tower placement.

Build 2 Steelworks and use temporary tents as template for building the streets.

Today is warmer at -30 C.


Decline to give double rations to children. Dismiss gravely ill workers so they can head to medical tent to stay alive and temporarily dismantle Cookhouse so they do not detour.

Upgrading Steelworks to Steam and both towers to Guard.

The Foreman ability needs to be used together now with Emergency Shifts.


More survivors were found and sent home alone at first to be rejoined later by Scouts.

Build Infirmary and squish in with temporary streets. More tents are needed for future survivors.

From now on, the Foreman ability needs to be used on all fully staffed buildings before 06:00.


Build Bunkhomes now in 2nd ring within tower range. Dismantle 1 of 2 Med Tents.

Continue upgrading to Bunkhouses and build 2 Resource Depots next to Steelworks.


Build Coal Thumper and Gathering Post.

Temperature has dropped to -50 C today.


Dismantle the depleted Gathering Post and Sawmill.


Build 2 more gathering posts (4 Total) next to the Coal Thumper and upgrade to Steam.

Build 2 Hunter Hangars near Cookhouse on same ring. Build Fighting Arena next to each Guard Tower.

Patrol can now be used to further reduce discontent!


Upgrade to Houses and build more Fighting Arenas and Guard Towers. Another Sawmill is needed:

Build 3rd Resource Depot next to the ones behind Steelworks. Continue upgrading to Houses.

Build new Saw Mill while deleting old one.

The most important day before the big date tomorrow with Ms. Storm! Are you ready?!


Transferred workers from one Steelworks to a Sawmill. Disband healthy scouts only.

Delete depleted Sawmill and nearby Gathering Post. Get another Saw Mill.

Build 2 Infirmaries and dismantle the old one.

Continue upgrading to Houses.

At 23:00, one time exception of using Gen Power Level 2 instead of Overdrive to use the ability more during the Storm)

Build 4 Steam Hubs at Workplaces, especially the Infirmary since it needs to work 24/7. The very top one shows two hubs, there is one on the right next to Steelworks. All 4 locations are in the three screenshots.

All conditions of the checklist must be met to ensure that storm can safely pass without causing problems. The first storm gives a -5 weather level penalty at -70 C with all food production disabled!

The storms arrives exactly at 07:00 and disables all food production. The exceptions are the hunters returning from last night and Hothouses working for just one hour on extended shift. The Cookhouse still needs to be employed until all rations are made.


During the storm, focus on upgrading all homes to houses to reduce sickness and build a 5th Gathering Post next to Coal Thumper.

Dismantle the last Med Tent & Build Snow Pit next to Resource Depot behind Steelworks.


The infirmary will need to use extra rations for speedy recovery as illness increases due to the punishing cold!

The storm ends exactly at 07:00 and temperatures warm up to -40 C. All Steam Hubs can be shut off and set generator back to level 1. The time for recovery is now and prepare for the next storm!


The Scouts need to be created again to explore the new map! Additionally, 3rd scouts will be available after research.

Relics will be available after the first storm and up to 3 artifacts can be collected at a time. The next storm will reset the map with fresh scouting locations.

The scouts can safely get most of the relics safely with the cheapest option of wood and steel. Save-scumming is needed when going for more expensive options to save Steam Cores.

A new achievement will be given, once everything is complete:

The Propaganda Center can be built in front of the right Steelworks and needs to be either unemployed or dismantled after temporarily sending an Engineer to work there. This will avoid scripted death event.


Begin to relocate 2 Workshops behind the Infirmaries and dismantle old ones later.

Build 3 Agitators but none for Steelworks. They should be built for Sawmills, Gathering Posts/Coal Thumper, and Infirmaries/Workshops.


Build 3 Resource Depots next to the ones behind Steelworks and extends to the back of the coal mines.

Build 2 more Hunter Hangars next to the current ones and squish in with streets. Dismantle depleted Sawmills and replace with fresh ones.

Build 5 houses on 3rd ring behind the Stockpiles and refer to the Perfect City Management guide.

Temperature dropped to -70C and same temperature as first storm.Generator needs more power and Steam Hubs need to be turned on.


Build more Houses on 3rd ring and get two more Workshops behind the current ones.

Build Sawmills near Wall Drill sites to clear the trees away.

The weather is warmer today at -60C and Steam Hubs can be turned off.


Build 2 Coal Mines, Steam Thumper, and 2 more Gathering Posts.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2811523640

Dismantle Hothouses to upgrade Coal Mines with the salvaged Steam Cores.

No preparation is needed due to the overflowing surplus of resources!


Build a Steam Hub for the Coal Mines.

The infrastructure is now more than adequate to weather any storm and survive past 100 days!

Each successive storm after the second will be colder by -10 C and arrive in 7 days with the same duration of 2 days. For another achievement, do not build any automatons until after 75 days.

In the late game, Workshops are dismantled after completing essential research. The only research that is mostly useless are any upgrades to Sawmill and cheaper House/Prosthetics/Automatons.
