Colossal Order's 2023 sequel simulates every citizen as an agent with a household, a job, an education level and a daily route between them. Twenty milestones gate progress from Tiny Village to Megalopolis, handing out 432 expansion permits and 232 development points along the way. The Economy 2.0 patch reworked rent, production and taxation after launch, so a lot of the advice written in the first months no longer matches the game.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Agent based citizen simulation
Each citizen carries a home, a workplace, an education level and a route, and traffic is the sum of those individual routes rather than an abstract flow. A factory with no transit link nearby simply fails to fill its jobs.
Milestones and expansion permits
Twenty milestones run from Tiny Village to Megalopolis, and clearing all of them grants 432 expansion permits plus 232 development points. Each permit buys one map tile, so land is something you earn rather than a setting you choose.
Development tree upgrades
Development points unlock service buildings and upgrade branches such as extra school capacity or additional landfill cells. Points are scarce for the first several milestones, so roads, health and education branches pay back faster than niche unlocks.
Production chains and outside trade
Industry draws on raw resources like grain, ore, oil, wood and stone, and anything you cannot extract locally is imported through road, rail, ship or air connections. Import costs eat margins, which is why a map with two usable resources runs cheaper than one with none.
Land value and pollution
Ground pollution, air pollution and noise all suppress land value, and land value drives rent and which density will actually build. Put a landfill upwind of housing and the district empties long before the health warnings look serious.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Coal Power Plant | Cheap, reliable output that pollutes the air heavily and needs a coal supply. | Bridging the gap before renewables or nuclear, sited far downwind of any housing. |
| Water Pumping Station | Draws fresh water from a river or lake and pushes it into the pipe network. | Any city on a river map, placed upstream of every sewage outlet you own. |
| Wastewater Treatment Plant | Cleans sewage before it returns to the water body instead of dumping it raw like a sewage outlet does. | Any city past a few thousand citizens, and mandatory on maps where you pump from the same river you drain into. |
| Landfill | Stores garbage rather than destroying it, and fills up permanently unless you empty it into an incineration plant or recycling centre. | A short term dump on a fresh city, placed on cheap land you will never zone. |
| Elementary School | The first education building and the base of the whole education chain. | Every residential district from the first few hundred citizens onward. |
Coal Power Plant: Cheap, reliable output that pollutes the air heavily and needs a coal supply. It is the standard early generator when wind alone cannot cover a winter demand spike.
Water Pumping Station: Draws fresh water from a river or lake and pushes it into the pipe network. Intake quality matters, because contaminated water reaching taps produces a sickness wave that reads like a healthcare failure.
Wastewater Treatment Plant: Cleans sewage before it returns to the water body instead of dumping it raw like a sewage outlet does. It costs more upkeep and is the fix for a river that has turned brown.
Landfill: Stores garbage rather than destroying it, and fills up permanently unless you empty it into an incineration plant or recycling centre. Ground pollution spreads from it for as long as it sits there.
Elementary School: The first education building and the base of the whole education chain. Without it, citizens stay uneducated and can only fill basic industry jobs, which caps your tax income permanently.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Lakeland | First city, beginner friendly | Grain fields, abundant fresh water, wide flat building room |
| Sweeping Plains | First city, beginner friendly | Flat unrestricted building space, mild climate, easy highway access |
| Barrier Island | Second or third city | Fishing industry, ship connections, coastal land value |
| Great Highlands | Experienced builders | Heavy forest cover, dramatic terrain, forestry specialisation |
| Waterway Pass | Intermediate | Large buildable area, river freight routes, mixed resources |
Lakeland: European theme with a cold climate swinging roughly from minus 15 to 26 degrees, plenty of flat land and extensive grain resources around the lakes. Heating demand in winter is the main thing to plan for.
Sweeping Plains: North American theme with a temperate climate and mostly flat terrain, which removes almost every terrain excuse for a bad road layout. Resources are moderate rather than rich.
Barrier Island: North American theme with a warm coastal climate and fish resources offshore. Land is split by water, so bridges and ferry routes become part of the plan rather than decoration.
Great Highlands: European theme with a cool climate and mountainous terrain that limits buildable space badly. Forest resources are strong, which makes it the natural forestry map if you can handle the slopes.
Waterway Pass: North American theme with an extreme climate range from about minus 5 to 36 degrees and a large buildable area along a river passage. Power demand swings hard in both directions across the year.

Tips That Actually Matter
- Start with one two lane road off the highway connection and zone shallow along it. Deep zoned blocks create buildings that back onto nothing, and citizens who cannot reach a bus stop will drive instead, which is where early traffic problems begin.
- Spend your first development points on the elementary school and medical clinic branches. Uneducated citizens can only fill basic industry jobs, and a city stuck at low education imports every processed good it needs at full price.
- Taxation is set per education level and per industry type, not as one slider. Raising rates on well educated office workers while keeping industry low is how you fund services without triggering a move out wave.
- Every expansion permit buys exactly one tile and the twenty milestones only ever hand out 432 of them. Prioritise tiles containing grain, ore, oil, forest or an outside connection over tiles that merely look flat and scenic.
- Traffic runs on real pathfinding, so one badly placed intersection near an industrial area backs up an entire district. Build a dedicated freight route to the highway before you consider widening anything.
- Place the wastewater treatment plant downstream of the water pumping station on the same river. Pumping your own sewage back into the taps produces a sickness spike that most players misdiagnose as a hospital shortage.
- Landfills fill permanently and keep polluting after they are full. Build an incineration plant or recycling centre before the landfill reaches capacity, then start emptying it, because an emptying landfill still needs somewhere to send the trash.
- Cold maps like Lakeland drop to about minus 15 degrees, and heating demand pushes power use well past the summer peak. Keep clear headroom above your warm weather load or the first cold snap browns out half the city.
- High density will not build just because you zoned it. Land value has to support it first, which means services, low pollution and transit access, otherwise the plots stay empty or the buildings level back down.
- Mods come through Paradox Mods rather than the Steam Workshop, and the map and asset editor arrived after launch. Install a road tools mod before attempting a large interchange by hand, because the stock tools fight you on elevation.
Common Mistakes to Avoid
- Zoning high density before land value can support it, which leaves plots empty or buildings levelling back down while you wonder why demand looks strong.
- Buying map tiles for the view. Permits are finite, and a tile with no resource and no outside connection adds service upkeep without adding income.
- Treating every jam as a road width problem. Adding lanes to a junction everybody routes through just relocates the queue a hundred metres further back.
- Siting a landfill or coal plant upwind of housing. Ground and air pollution crush land value, and citizens move out well before the health icons look alarming.
- Following launch era guides. Economy 2.0 changed rent, production and taxation, so the old budget numbers and tax rate advice no longer line up with the current build.
Frequently Asked Questions
How many maps come with the base game?
Twelve: Archipelago Haven, Barrier Island, Corral Riches, Great Highlands, Lakeland, Mountain Village, River Delta, Sunshine Peninsula, Sweeping Plains, Twin Mountain, Waterway Pass and Windy Fjords. Tampere Valley came as an edition bonus rather than base content.
How do I unlock more land?
Through milestones. The twenty milestones grant 432 expansion permits in total, and each permit buys one map tile. Spend them on tiles with resources or an outside connection first.
Does Cities: Skylines II support mods?
Yes, through Paradox Mods rather than the Steam Workshop, which means the same mod library works across platforms. The map and asset editor shipped after launch.
Why does my city keep losing money?
Usually over building services for the population you have. Check upkeep on schools, hospitals and transport lines against your tax base, and cut lines that carry almost nobody before touching tax rates.
Which map is best for a first city?
Lakeland or Sweeping Plains. Both give you large flat areas and usable resources, so your early mistakes stay road layout mistakes rather than terrain disasters.
