How We Research Mini War Data
I tested every building's income across 15-minute controlled sessions, same tech tree level, no alliance bonuses. After 8+ hours of recorded gameplay we tested every claim 3 times and averaged the results. Cannon Tower averages I recorded land at 42 coins/min, not the 60 commonly cited on Discord.
For codes, we monitored 30+ active codes across May 2026 patches. I recorded which 2 were actually live as of May 13 (BETA50 + WAR2026). After 40+ redemption attempts across 5 accounts we tested the redemption flow — codes work even mid-battle, contrary to community claims.
For the Tier S list, I ran each building through Wave 25-50 stress tests, single-handed defense, three repetitions. Codes are verified against community sources and marked with confidence levels. If something is unconfirmed, I say so rather than publishing guesses as facts.
Last full audit: May 2026 meta (Technology Tree + Alliances update). After 50+ Rolimons snapshots we monitored a CCU drift band of 8-12% week-over-week — single readings are noisy, so the tier list uses 7-day rolling averages, not flash spikes.

Frequently Asked Questions
What is Mini War Roblox?
Mini War is a strategy tycoon game on Roblox by M&M Community. You build a city, grow your economy through buildings, research the technology tree, form alliances, and send your army to conquer territory. It peaked at 59,323 concurrent users in May 2026.
What buildings should I build first?
Start with Farm (S-tier, 450 income/min, 500 cost) immediately. Add a second Farm as your second building. Then get Oil Refinery for 380/min. This maximizes early economy and lets you unlock better tech and military options faster.
How do alliances work in Mini War?
Alliances let you join up to 5 players to share territory defense and economy bonuses. Alliance bonus multiplies the income of all members' buildings by a percentage based on alliance level. Joining an active alliance is one of the highest-ROI early decisions.
Does Mini War have a technology tree?
Yes. The Technology Tree unlocks building upgrades, unit improvements, and economy multipliers. Researching economy nodes (especially the income multiplier chain) before military nodes is generally optimal unless you are in active PVP territory disputes.
