Mini War rewards players who get their economy moving fast and then transition cleanly into air and missile power. Building choices in the first ten minutes carry the most weight, because a single overpriced structure can stall your income and cost you territory in the mid-game. The rankings below sort factories, military buildings, and houses by real impact, then list the exact costs and production figures so you can plan a build order without guessing.
Quick answer: Open with 2–3 Farms, add an Oil Refinery as soon as income stabilizes, then layer in a Factory before spending on military. Late-game power comes from Air Base (Black Hawks) plus Missile Launcher.
Mini War building tier list (May 2026 meta)
The current meta favors explosive early economy that snowballs into air superiority and long-range missile threat. Farms and refineries dominate openers, while late-game strength rests on mythic and secret military structures backed by tech tree multipliers.
| Tier | Buildings | Why it ranks here |
|---|---|---|
| S | Farm, Oil Refinery, Air Base (Black Hawks), Missile Launcher, Rocket Bunker | Best income-to-cost ratios early; air mobility and burst firepower decide late games. |
| A | Market, Mine, Factory, Tank Base / Big Tank Base, Heli Pad | Strong mid-game income and frontline value with low risk. |
| B | Barracks, Power Plant, Research Lab, Sniper Tower, General’s Base | Useful but situational; many unlock tech rather than win fights outright. |
| C | Border Tower, Vehicle Base, Special Forces, Warehouse / Housing | Cheap starter or support value that does not scale. |
| D | Basic Turrets / Walls, Radar | Pure defense or visibility with no income and high opportunity cost. |
S Tier breakdown
Farm is the clear best opener. Its income-to-cost ratio is unmatched, and payback can land under two minutes with good placement. Stack several early, then pair with houses for population and markets for trade. The main weakness is that Farms are vulnerable without cheap early defense.
Oil Refinery received a buff in the May 2026 balance pass and now delivers strong sustained income that scales into the late game. It works well alongside factories and power plants for multiplier chains and is the cleanest way to move beyond basic farming.
Air Base (Black Hawks) dominates late. Fast, flexible air units excel at raiding, map control, and supporting ground pushes, and they pair naturally with missile launchers for combined arms. Missile Launcher adds area denial and burst damage; keep it positioned safely behind your tank lines. At the top end, the Rocket Bunker is the most expensive structure in the game and provides endgame firepower.
Factories ranked by cost and production
Factories are the backbone of your economy. Early structures are cheap and fast, while late-game generators demand huge investment and long build times but produce far more per cycle. The table below lists each factory with its cost, resource, build time, and production rate.
| Factory | Cost | Resource | Build Time | Production |
|---|---|---|---|---|
| Wheat Farm | $150 |  Wheat | 7s | +6/10s |
| Corn Farm | $150 |  Corn | 8s | +6/10s |
| Coal Cave | $500 |  Coal | 13s | +6/10s |
| Tree Farm | $1K |  Wood | 16s | +6/10s |
| Wood Plant | $1K |  Wood | 5m | +20/10s |
| Windmill | $1.8K |  Flour | 19s | +6/10s |
| Carrot Farm | $6.5K |  Carrot | 21s | +6/10s |
| Library | $9K |  Books | 27s | +6/10s |
| Oil Rig | $13K |  Oil | 30s | +6/10s |
| Iron Cave | $80K |  Iron | 20m | +6/10s |
| Cement Plant | $180K |  Cement | 30m | +6/10s |
| Gold Cave | $450K |  Gold | 45m | +6/10s |
| Bank | $1M |  Coin Bag | 60m | +6/10s |
| Research Lab | $5M |  Research | 1h 15m | +6/10s |
| Diamond Cave | $7.5M |  Diamond | 1h 30m | +6/10s |
| Uranium Cave | $10M |  Uranium Ore | 2h | +15/10s |
| Nuclear Reactor | $20M |  Stable Uranium | 3h | +12/10s |
| Data Center | $50M |  Data Cube | 3h | +16/10s |
| Blackhole Generator | $1B |  Dark Matter | 24h | +48/10s |
| Area 51 Lab | $7.5B |  Alien Essence | 48h | +30/10s |
| Antimatter Reactor | $50B |  Antimatter | 48h | +16/10s |
| Quantum Core Generator | $250B |  Quantum Core | 72h | +18/10s |
Note: The Blackhole Generator stands out among late-game factories. It carries the highest production rate in the list at +48/10s with a 24-hour build, making it the strongest single income source before the multi-billion secret tiers.
Military buildings ranked by cost and units
Military structures unlock progressively as your income climbs. Early defense comes cheap, but the units that win late-game fights, including Black Hawks and rocket artillery, sit behind major investments. The table below lists each military building with its cost, the units it produces, and unit health.
| Military Building | Cost | Units | HP |
|---|---|---|---|
| Border Tower | $150 |  1 Soldier | 120 HP |
| Barracks | $750 |  2 Soldiers | 100 HP each |
| Sniper Tower | $4K |  1 Sniper | 80 HP |
| Vehicle Base | $8K |  2 Light Vehicles | 600–750 HP |
| Tank Base | $25K |  2 Tanks | 1,000 HP |
| Helipad | $140K |  2 Heavy, 1 Light Helicopter | 600–1,200 HP |
| Special Force | $300K |  Mixed Infantry | 150–200 HP |
| Missile Hangar | $600K |  2 Rocket Trucks, 1 Rocket Unit | 120–400 HP |
| Hangar | $1.2M |  3 Fighter Jets | 900 HP each |
| Big Tank Base | $2.4M |  4 Modern Tanks | 1,500 HP each |
| Big Hangar | $3M |  4 Fighter Jets | 800 HP each |
| Missile Launcher | $4.5M |  Missile System | N/A |
| Military Hospital | $7.5M |  Ambulance | 1,650 HP |
| General’s Base | $10M |  5 B2 Bombers | 1,200 HP each |
| Air Base | $50M |  2 Black Hawks | 1,500 HP each |
| Artillery Depot | $250M |  2 Rocket Tanks | 3,000 HP each |
| Rocket Bunker | $5B |  2 Elite Artillery | 2,750 HP each |
| Mech Station | $25B |  2 Mech Units | 4,500 HP each |
The Rocket Bunker is the most expensive building in Mini War at $5 Billion, with Secret rarity. Mech Station units carry the highest individual health at 4,500 HP each, which is why they anchor elite late-game ground compositions.
Houses ranked by cost and population
Houses raise your population cap so you can support more factories and keep production running. Build one or two early, then upgrade as your economy grows. The table lists each house with its rarity, cost, and population bonus.
| House | Rarity | Cost | Population |
|---|---|---|---|
| Small House |  Common | $300 | +3 |
| House |  Common | $700 | +4 |
| Villa |  Uncommon | $3K | +5 |
| Apartment Building |  Uncommon | $7.5K | +6 |
| Modern Block |  Rare | $40K | +8 |
| Skyscraper |  Epic | $400K | +10 |
| Helix Tower |  Legendary | $2.5M | +13 |
| The Manor |  Mythic | $10M | +14 |
| Giant Skyscraper |  Secret | $1B | +30 |
| Double Turbo Tower |  Secret | $25B | +55 |
Build order for fast progression
The most common mistake is over-investing in defense too early. Border Towers and basic turrets generate no income, so build only what you need to survive while your economy compounds. Join an alliance early for shared bonuses and protection, and check the in-game build menu for exact costs and build times before committing to a large purchase, since values shift with balance updates.
