Build and Conquer City Levels & Population Gates

City levels are the quiet progression spine of Build and Conquer. You can place pretty factories all day, but military unlocks and late research still hinge on population milestones. This guide gathers what the community has verified in V0.2 beta: city level 2 ≈ 250 population (guns and soldiers), city level 5 ≈ 2,500 population, and the awkward middle where levels 3–4 are not cleanly published by The Slop Company yet.

Use this page with Getting Started for early housing and Make Money Fast so your new citizens actually fund research. For the wider loop, see How to Play.

Why city level matters

City level is not a vanity badge. It gates:

• Basic military — guns and soldiers at level 2
• Heavier research ambitions — large missile programs often want around level 4 in community testing
• Dense prestige builds — level 5 territory where glass-tower-scale housing (~180 pop contribution in community notes) makes sense

If missiles feel permanently locked, check hit quests on the Missile Guide and your city level — both can block you.

Known population gates

City level	Approx. population	Community notes
1	Starter	Empty-plot onboarding
2	~250	Unlocks guns and soldiers
3	Unpublished officially	Grow through housing + utilities; watch tooltips
4	Unpublished officially	Often cited before big missile research
5	~2,500	High-density end of mid-game; showcase towers

Treat unpublished middle levels as soft targets: keep climbing population without assuming a magic building alone skips the climb.

How population actually rises

Population comes from housing capacity and livable conditions:

1. Place homes on a coherent road grid (Controls — hold left-click drag).
2. Cover new blocks with power and water before wondering why numbers freeze.
3. Mix housing tiers as they unlock instead of spamming only the weakest shack forever.
4. Keep shops / supermarkets funded so you can afford the next housing wave.
5. Avoid industrial pollution of your only residential corridor when the layout allows separation.

A glass tower style build around level 5 is a density tool, not a day-one flex. Early game wants many modest homes; late mid-game wants vertical or high-capacity structures once utilities scale.

Sprint plan to city level 2 (~250 pop)

Goal: unlock guns and soldiers without bankrupting shops.

1. Finish starter roads and a rectangular housing district.
2. Guarantee power + water on every occupied block.
3. Open shops as soon as foot traffic exists — retail funds more roofs.
4. Add farms once cash is stable; do not skip utilities to rush factories.
5. Count population every few minutes; fill gaps with homes rather than random monuments.
6. At ~250, open military placement and train a defensive core.

If you stall at 180–220, you usually lack either utility coverage or road-accessible parcels, not “RNG.” Re-read placement habits in Getting Started.

Mid levels (3–4) — play the tooltips

Because official thresholds for levels 3–4 are not cleanly published, use this discipline:

• Believe the in-game city level readout over memory of a YouTube short
• Continue housing expansion in planned rings
• Stand up a research office during this band
• Begin light mainland scouting only if income survives army upkeep
• Prepare industry for fuel / steel before mass missiles

Community players often align major missile research with roughly city level 4. If the research button is grey, check level, cash, and prerequisite buildings before grinding hit quests endlessly.

Roadmap to city level 5 (~2,500 pop)

2,500 population is a logistics project:

• Expand parcels carefully — leftover pockets beat one giant unserviced sprawl
• Upgrade to higher-capacity housing when available
• Scale supermarkets, not only corner shops
• Multiply power/water plants ahead of demand spikes
• Use mainland strategic area holds for community-reported ~+30% population and ~+20% income buffs (Mainland Warfare)
• Consider optional more city slots game pass (~249 R$, community-reported) only if you are plot-capped and already efficient

At this stage, a glass tower (~180 pop community note) is a chunky brick in the wall, not the entire wall. Keep diversified housing so one demolition or bug does not erase your level.

City level vs other progression tracks

Track	What it unlocks	Synergy with city level
Population / city level	Military gates, research eligibility	Primary soft gate
Cash from shops	Build speed	Funds housing waves
Hit quests	Missile tiers	Needs level + research office
Mainland holds	Income / pop buffs	Speeds level 5 grind
Game passes	Slots / packs / billboard	Optional accelerators

Codes are not a track — none confirmed on Codes as of November 2026.

Utility failures that fake a pop soft-cap

Before you assume a hidden level lock:

• Blackouts on half the district
• Water missing on new towers
• Homes placed without road access
• Beta building states that need a rejoin (8-player servers can be weird)

Fix utilities, then re-check population. Only then push research or tunnels.

Military timing tied to levels

• Pre-level 2: pure economy and utilities
• Level 2: guns, soldiers, local defense
• Approaching ~4: research office heavy; start SRBM/GLCM hit quests
• Level 5 band: sustain mainland campaigns, layered air defense, denser income

Unit roster flavor — drones, tanks, HIMARS, missiles — still needs the industry chain described in Make Money Fast and tactics in Mainland Warfare.

Checklist

• Road grid leaves expansion lanes
• Power/water cover all lived housing
• Shops scale with population
• Tracking toward 250 for level 2
• Research office planned before missile push
• Strategic area buffs considered for 2,500 grind
• No reliance on wrong-game codes

City level is a population math problem dressed as a military unlock tree. Roof the plot, light the plot, water the plot, monetize the plot — then the guns turn on. When the counter finally rolls, return to the Guides Hub and pick missiles or mainland as your next chapter.
