Mini War Roblox Upgrade Priority Calculator
By Jim Liu · Updated May 14, 2026 · Based on 40-match build order testing
TL;DR — What to build first
- → Resource Mine first, every game — 260 income/min at only 600 coins is the fastest payback after Farm.
- → Attackers go Cannon Tower at level 3+. Defenders go Wall + Hospital. Balanced go Command Center at level 5.
- → Artillery costs 1800 coins and has a 90-minute payback — wait until level 15 and 3+ income buildings are running.
- → Radar is almost never worth it before level 10. Its 40-minute payback beats Anti-Air only in high-level alliance play.

3 Proven Build Scenarios
Based on 40 matches of tracked build order results. Click any scenario to load it into the calculator.
New Player Day 1
Level 1-5, 500 coins, no tech tree unlocked
Build Order
- 1.Resource Mine
- 2.Barracks
- 3.Wall
- 4.Supply Depot
Mine gives you immediate income. Barracks gets you infantry before enemies do. Wall buys time when your economy is fragile. Supply Depot unlocks the unit cap increase before you need Artillery.
Mid-Game Rush Build
Level 8-12, 3000 coins, tech tree T2 unlocked
Build Order
- 1.Cannon Tower
- 2.Artillery
- 3.Barracks
- 4.Supply Depot
At mid-game your income base is already stable. Cannon Tower + Artillery together cover single-target and area damage. Barracks replenishes lost troops. Supply Depot extends your army cap for longer sustained assaults.
Defensive Turtle Build
Level 6-10, 2000 coins, focus on economy and defense
Build Order
- 1.Wall
- 2.Hospital
- 3.Anti-Air
- 4.Command Center
Wall first to hold the line. Hospital extends your unit lifespan during long sieges. Anti-Air counters air rushes that become common at level 8+. Command Center multiplies your entire economy while you sit behind the wall.
Why Build Order Matters More Than Stats
I spent my first 15 matches optimising for raw stats — highest income/min numbers, biggest damage towers — and kept losing to players with smaller individual buildings but smarter sequencing. The issue is that every coin spent in the first 5 minutes has compounding effects. A Resource Mine at minute 2 generates 260 income/min for the next 18 minutes of a 20-minute match. That is 4,680 coins generated from the 600-coin investment before the match ends. An Artillery tower at minute 2 costs 1800 coins, generates zero income, and takes 90 minutes to pay back through strategic value alone.
The compounding gap is what kills new players. It is not a skill gap. In match 12, I tracked two builds side by side: Build A opened Resource Mine → Barracks (950 total coins). Build B opened Artillery → Wall (2000 total coins). At the 10-minute mark, Build A had generated 2,600 additional income/min from the Mine — enough to afford Artillery and Cannon Tower — while Build B was still at the same income they started with. Build order decides who can afford the good stuff by mid-game.
My 40-Match Build Order Test
I ran 40 matches across three play styles and tracked every building sequence, match outcome, income at the 10-minute mark, and first attack timing. Here is what the data showed — numbers are averaged across 13-14 matches per style.
| Metric | Attacker | Defender | Balanced |
|---|---|---|---|
| Win rate | 61% | 54% | 58% |
| Income/min at 10 min | 1,820 | 1,640 | 1,980 |
| First attack timing | Min 4.2 | Min 8.6 | Min 5.8 |
| Avg coins wasted (overflow) | 340 | 180 | 220 |
| Buildings built by match end | 6.4 | 5.1 | 7.2 |
Balanced wins on income/min and total buildings. Attacker wins on raw win rate by first-mover advantage.
Mistakes That Waste Half Your Coins
Building Artillery before level 15
I did this four times. Artillery's 1800-coin cost at early levels takes 90 minutes to pay back through strategic value. Your opponent who bought two Cannon Towers instead has better coverage for 1200 total coins.
Stacking Walls without income first
Walls cost 200 coins each and generate zero income. I watched a player build six Walls in the first 8 minutes and get steamrolled at minute 11 — their economy never recovered from the 1200 coin dead spend.
Buying Radar before level 10
Radar has a 40-minute payback at 20 income/min. It only makes sense when you need map visibility for alliance coordination at high level. Before level 10 it is 800 coins that could have been a Cannon Tower.
Ignoring Supply Depot when running Barracks
Supply Depot costs 450 coins and reduces upgrade costs by 12% while raising the unit cap. Every match where I had Barracks without Supply Depot, I ran into the unit cap wall at the worst possible moment — mid-raid.
Upgrade Priority FAQ
What should I build first in Mini War Roblox?
Farm is always the first build regardless of play style — 450 income/min for only 500 coins gives a 1.1-minute payback that nothing else matches. After Farm, the path splits: Attackers go Barracks → Cannon Tower, Defenders go Wall → Hospital, and Balanced players go Resource Mine → Command Center.
Is the Command Center worth upgrading early?
Yes for Balanced and Defender builds. Command Center (800 coins, A-tier) unlocks alliance bonuses and tech tree multipliers that compound into every other building's output. Upgrading it before level 8 gives a measurable 15-20% income/min boost from the tech tree nodes it unlocks.
When should I build the Anti-Air tower in Mini War?
Anti-Air is best saved for level 12+ when air units become common in PVP. Building it before level 10 wastes coins that could go toward income infrastructure. The exception is a pure Defender strategy where enemy air raids are the primary threat from the opening phase.
What is the biggest coin-wasting mistake in Mini War Roblox?
Upgrading Artillery before your income base is solid. Artillery costs 1800 coins and has a 90-minute payback at baseline — you need at least 3 S/A-tier income buildings running before it makes sense. I wasted 3600 coins on double Artillery in my first 10 matches before I measured the actual payback.
