Merge a Mini Army drops up to five players onto one map and turns them loose to conquer it. You start with a trickle of weak troops spawning at your base, and everything you do afterward feeds one loop: combine duplicate units into stronger ones, send those units out to seize territory, and pour the resulting Cash back into upgrades. Territory keeps earning even while you are offline, but rivals can take it from you, so holding ground matters as much as taking it.
Quick answer: Merge two identical units to create one of the next tier, then spend Cash on the Spawn Tier upgrade first so higher-tier units appear at your base automatically. Once you have a deployed army, walk into a garrison, army compound, or airbase and hold the Interact key to capture it and raise your Cash income.

How merging builds stronger troops
Every player starts with Pistol units spawning at their base, and merging is how you climb past them. Pick up one unit, drop it onto an identical one, and the two combine into a single troop one tier higher with much more health and damage. Merge two Pistols and you get an SMG unit. Combine two Tier 32 units and you get a single Tier 64 unit that hits far harder than either half did.
Each new tier you unlock is recorded in your Index, so the game tracks how far up the ladder you have reached. Beyond health and damage, every unit carries a Cash-per-second value, and higher tiers generate more money. That means merging is not just about combat power. It is also the fastest way to raise your passive income.
Spend Cash on the right upgrades
Cash builds up on its own from your units, and you feed it into three upgrades. Each purchase raises the cost of the next one in that line, so the order you buy them in matters.
| Upgrade | What it does |
|---|---|
| Spawn Tier | Raises the tier of units that spawn automatically at your base |
| Max Deployed | Increases how many units you can send into battle |
| Base Capacity | Increases how many units spawn at your base |
Prioritize Spawn Tier. When higher-tier units start appearing at your base by default, every merge begins from a stronger point, which compounds into more powerful troops and more Cash. When you want a bigger attacking force to throw at enemy territory, put Cash into Max Deployed to raise your army size.
Capturing garrisons, compounds, and airbases
There are three kinds of territory to take: garrison, army compound, and airbase. Every one you hold adds to your Cash earnings, so seizing them is the main way to accelerate your economy beyond base spawns alone.
You cannot attack another player’s base directly. You can only take their territories, and either side can contest a captured site. Because of that, sending reinforcements to defend the ground you have claimed is what keeps its income flowing.
Rebirths and unlocking more troops
A Rebirth wipes your units and Cash and sends you back to the start, but it pays off in two ways. It unlocks additional troops and raises your Cash multiplier, so each run after a Rebirth earns faster than the one before.
The first Rebirth becomes available once you merge your way to the 22nd troop in the Index. Later Rebirths ask for more merging than the one before, so each reset takes a longer stretch of play to reach.
Put together, the game rewards a steady rhythm. Merge whatever duplicates appear, push Spawn Tier up so those merges start higher, expand your deployed army when you are ready to fight, and use captured territory to fund the next round of upgrades before rebirthing for permanent multipliers. You can jump into Merge a Mini Army on Roblox and start collecting Pistol units right away.
