merge a mini army upgrades: Core Progression
Merge a Mini Army uses a loop built around spawning, merging, upgrading, deploying, and eventually Rebirthing. The most important early decision is how to spend Cash without slowing down the next unit milestone. Upgrades can improve the quality of units entering your base, while merging combines those units into stronger troops.
The central progression system is not simply about buying every available improvement. You need to balance immediate Cash growth with the unit tier required for your next Rebirth. A higher Spawn Tier upgrade is especially valuable when your base begins producing units that are too weak to merge efficiently.

Spawn Tier
Raises the tier of units that appear in your base. This is the most direct upgrade priority when you are pushing toward a Rebirth requirement.
Cash Multiplier
Rebirth increases your Cash multiplier. The first Rebirth gives +100%, while the second gives +200%, according to the available 2026 guide information.
Merge Capacity
Rebirth expands your merging options and makes higher-tier unit progression possible after the reset.
| Upgrade Focus | Main Purpose | Best Timing |
|---|---|---|
| Spawn Tier | Produce stronger starting units | Prioritize before a Rebirth push |
| Cash spending | Fund upgrades and unit production | Spend when it improves the next milestone |
| Merging | Advance the unit index | Continue until the required unit appears |
| Deployment | Capture strategic locations | Use strong units after reaching the needed tier |
Use Cash on Spawn Tier when the next Rebirth requires several more merges. Stronger starting units make the entire progression cycle more efficient.
How Rebirth Changes Your Upgrades
Rebirth functions as a soft reset. Activating it deletes your current Cash, upgrades, and units, so the timing of the reset matters. The reward is a larger progression ceiling, more merging options, and a stronger Cash multiplier for the next run.
The first Rebirth is tied to the Supersonic Jet, identified as the 22nd unit in the index. The second Rebirth requires the unit listed at index 27. These requirements mean that a player should not reset simply because the button is available; the reset should support a deliberate plan for reaching the next tier range.
| Rebirth | Requirement | Immediate Cost | Main Reward |
|---|---|---|---|
| First | Obtain the Supersonic Jet, index unit 22 | Cash, upgrades, and units are deleted | +100% Cash multiplier and Tier 4.19M through Tier 67.1M |
| Second | Obtain index unit 27 | Cash, upgrades, and units are deleted | +200% Cash multiplier and Tier 134M through Tier 2.14B |
The first reset unlocks Tier 4.19M, Tier 8.38M, Tier 16.7M, Tier 33.5M, and Tier 67.1M units for later merging and deployment. The second reset expands the available range to Tier 134M, Tier 268M, Tier 536M, Tier 1.07B, and Tier 2.14B.
Do not spend the last of your Cash on upgrades immediately before Rebirth unless the purchase helps you reach the required unit. The reset removes those upgrades.
A useful way to think about Rebirth is as an investment cycle:
- Before Rebirth, focus on reaching the required index unit.
- At the reset, accept the loss of short-term progress.
- After Rebirth, use the improved multiplier to rebuild faster.
- Once higher tiers are available, repeat the merge process toward the next requirement.
Step-by-Step Upgrade Route
The following route keeps your spending focused on measurable progression. It is designed around the two Rebirth milestones currently described for Merge a Mini Army in 2026.
Build a Stable Cash Flow
Start by spawning and merging units while keeping enough Cash available for useful improvements. Avoid treating every upgrade as mandatory; prioritize upgrades that help you produce or merge stronger units.
Raise the Spawn Tier
When early units are no longer helping you progress quickly, invest in the Spawn Tier upgrade. A higher starting tier can shorten the number of basic merges needed to reach later units.
Push Toward Index Unit 22
Continue merging until you obtain the Supersonic Jet, which is identified as the 22nd unit in the index. Use this unit for the first Rebirth objective before activating the reset.
Activate the First Rebirth
Confirm that you are ready to lose your Cash, upgrades, and units. Rebirth when the Supersonic Jet requirement is complete, then use the +100% Cash multiplier to rebuild.
Reach Index Unit 27
After rebuilding with the expanded merge range, continue advancing through the unit index until unit 27 is obtained. This enables the second Rebirth and access to the highest listed tier range.
| Route Stage | Primary Action | Avoid |
|---|---|---|
| Early run | Merge available units and build Cash | Buying upgrades without a progression goal |
| Mid run | Improve Spawn Tier | Delaying the next unit milestone for minor gains |
| First milestone | Obtain the Supersonic Jet | Rebirthing before the requirement is complete |
| Post-Rebirth | Rebuild with the stronger multiplier | Assuming deleted upgrades remain active |
| Second milestone | Reach index unit 27 | Ignoring the expanded high-tier merge range |
The strongest general route is to improve Spawn Tier, reach the required index unit, Rebirth, and then rebuild using the new Cash multiplier.
Deployment and High-Tier Unit Planning
Upgrades are connected to more than the base economy. Once you create stronger troops, deployment becomes the way to use that progress against garrisons, camps, and Apocalypse airfields. The first Rebirth guide specifically identifies the Supersonic Jet as a powerful unit for capturing these locations before resetting.
Higher-tier access is therefore valuable even when a unit is not immediately needed for the next merge. The second Rebirth’s Tier 2.14B ceiling is currently the highest tier listed in the available information, making it a long-term target for players who want the strongest tank and fighter-airplane progression described for the game.
Garrisons
Deploy improved troops after merging to pressure controlled locations. Use unit strength as a reason to delay Rebirth until the requirement is secured.
Camps
Camps provide another deployment objective for stronger units. Plan your merge route so deployment does not interrupt the next milestone.
Apocalypse Airfields
The Supersonic Jet is associated with capturing Apocalypse airfields before the first reset. Treat this as a milestone-use opportunity.
High-Tier Units
Second-Rebirth access extends the listed range to Tier 2.14B, supporting later tank and fighter-airplane progression.
| Unit or Tier Range | Progression Role | Practical Use |
|---|---|---|
| Supersonic Jet | First Rebirth requirement | Capture garrisons, camps, and Apocalypse airfields |
| Tier 4.19M–67.1M | First-Rebirth unlock range | Continue merging and deploying stronger troops |
| Tier 134M–536M | Second-Rebirth progression | Develop higher-tier army options |
| Tier 1.07B–2.14B | Highest listed range | Pursue the strongest documented late progression |
If deployment is part of your current objective, use the Supersonic Jet or another strong unit before resetting. Rebirth removes your existing units.
A practical late-run plan looks like this:
- Build enough Cash to support the next Spawn Tier improvement.
- Merge toward the next index milestone rather than chasing random upgrades.
- Deploy a strong unit when a location objective is available.
- Rebirth only after confirming that the current unit requirement is complete.
- Rebuild with the increased multiplier and newly unlocked tier range.
Upgrade Checklist and Milestones
Use this checklist to organize each progression cycle. It separates permanent-feeling goals from reset-sensitive resources, helping prevent an accidental loss of valuable preparation.
Essential Upgrade Milestones:
- Build Cash before purchasing major upgrades
- Raise Spawn Tier when early units slow progression
- Merge until the Supersonic Jet, the index 22 requirement
- Use strong units for garrisons, camps, or Apocalypse airfields
- Confirm Cash and upgrade losses before each Rebirth
| Milestone | Completion Check | Why It Matters |
|---|---|---|
| Spawn Tier improvement | Higher-tier units begin appearing | Reduces dependence on basic merges |
| Supersonic Jet | Unit 22 is obtained | Required for the first Rebirth |
| First Rebirth | Reset is activated | Grants +100% Cash multiplier and new tiers |
| Index unit 27 | Unit 27 is obtained | Required for the second Rebirth |
| Tier 2.14B access | Highest listed range is unlocked | Supports the current late-game ceiling |
The best upgrade routine is intentionally repetitive: earn, improve, merge, deploy, and reset. That loop becomes more productive after each Rebirth because the Cash multiplier and available merge tiers expand. However, every reset still carries a meaningful short-term cost, so careful timing remains important.
As of August 20, 2026, the available guide information lists two Rebirth levels. Future game updates may change requirements, unit indexes, or tier availability, so verify major system changes through the game’s current menus and official community channels.
Before pressing Rebirth, check three things: the required unit is complete, useful deployment is finished, and no remaining upgrade would meaningfully improve the current run.
