Progression Roadmap

Follow this path from your first bombs to rebirth. Each stage builds on the last, so don't skip ahead before your base is ready.

Swipe sideways to see all stages →

Stage 1

Starter Bombs

Goal: Clear early clutter
Focus: Merge low tiers fast to open space.
Common mistake: Holding onto weak bombs too long.

Stage 2

Better Nukes

Goal: Reach mid-tier nukes
Focus: Merge upward to unlock stronger units.
Common mistake: Skipping merges to rush a single nuke.

Stage 3

Income Upgrades

Goal: Build steady cash flow
Focus: Boost earnings before anything else.
Common mistake: Spending on cosmetics over income.

Stage 4

Raid Preparation

Goal: Get raid-ready
Focus: Stabilize income and stock resources.
Common mistake: Raiding with a fragile economy.

Stage 5

Base Defense

Goal: Protect your progress
Focus: Lock and organize before you leave.
Common mistake: Leaving the base open and exposed.

Stage 6

Rebirth

Goal: Reset for long-term gains
Focus: Check Rebirth 8–10 goals, then reset once growth clearly slows down.
Common mistake: Rebirthing before Overclocker, Barrier, or the Index gate is ready.

Stage 3 (Income Upgrades) maps to the in-game Store — see the full Store upgrades guide for Spawn Tier, Spawn Speed, and Lock Base priorities. After income is stable, unlock passive buffs via commanders — start with Salvager or Spotter. Redeem free cash first on the codes page.

Long-term scaling

Rebirth guide — tier checklist through Rebirth 10

Rebirth resets cash, nukes, and Store upgrades but keeps commanders and grants permanent multipliers plus higher Index tiers.

When to rebirth

Growth slows — merges no longer push you toward the next Index tier efficiently.
You have cleared enough missile tiers that the permanent money multiplier outweighs the reset cost.
You need higher rebirth-gated nukes for city farming or event maps (Rebirth 7–10 each added five Index entries; Rebirth 9–10 also raise cash to +120% / +130%).

What resets

Cash on hand and placed nukes on your plot.
Store upgrades (Spawn Tier, Spawn Speed, Max Spawn, Lock Base levels).

What you keep

Commanders you unlocked and their upgrade levels.
Permanent rebirth money multipliers and Index unlocks.
Nuke Mutations (August 1, 2026) — preserved nukes convert to Tier 1 nukes on rebirth.

The July 4, 2026 patch added Rebirth 7 with five new nukes. Rebirth when your current run has exhausted practical merges — not the moment you unlock the button.

The July 13, 2026 patch added Rebirth 8: +110% cash and 5 additional nukes (Silent Whisper, False Step, Peek-a-Boo, Colossus, Fragmenter). Requires the final nuke tier in the Index plus Overclocker and Barrier commanders equipped or owned — confirm exact UI requirements in-game. Use the quick requirement panel above, then pair rebirth timing with Overclocker and Barrier if you are chasing Rebirth 8 — commanders persist across resets and accelerate your next run.

The July 25, 2026 patch added Rebirth 9 (+120% cash, 5 nukes) and Rebirth 10 (+130% cash, 5 nukes). The August 1, 2026 patch also gates Admiral Mutations and a second Mutation slot behind Rebirth 10. Exact commander gates for 9–10 were not listed in the July 25 notes — check the Rebirth panel in-game.

August 1, 2026: Mutations unlock at Rebirth 3 (Legendary at 5, Admiral + second slot at 10). Rebirth preserves Mutations and converts preserved nukes to Tier 1. See /progression#mutations. Open the Mutations checklist.

Unlock walkthrough: /blog/how-to-unlock-nuke-mutations-merge-a-nuke-august-2026.

What do you need for Rebirth 8 in Merge a Nuke?

The July 13, 2026 patch added Rebirth 8 with +110% cash and 5 more nukes. Current reports say you need the final nuke tier in the Index plus Overclocker and Barrier owned or equipped. Confirm the exact requirement in the in-game UI before spending Robux or cash.

Do you need Overclocker and Barrier for Rebirth 8?

Yes, Overclocker and Barrier are reported as part of the Rebirth 8 gate. Overclocker is tied to faster laboratory spawns, while Barrier is a commander requirement players should secure before trying to unlock Rebirth 8.

What are the Rebirth 1–10 requirements in Merge a Nuke?

Verified on this wiki: Rebirth 3 unlocks Nuke Mutations, Nuke Locking, and Self Destruct (August 1). Rebirth 5 unlocks Legendary Mutations. Rebirth 6 raised the ceiling with the commanders launch (Hoplas2 footage). Rebirth 7 (July 4) adds five Index nukes. Rebirth 8 (July 13) needs Overclocker and Barrier for +110% cash and five nukes. Rebirth 9 (+120% cash, 5 nukes) and Rebirth 10 (+130% cash, 5 nukes) arrived July 25; August 1 also gates Admiral Mutations and a second Mutation slot behind Rebirth 10. Rebirth 1–2 / 4: check the in-game Rebirth panel.

What is the best early progression path in Merge a Nuke?

Codes → Spawn Speed → Spawn Tier → merge toward 16+ → capture a commander (Salvager or Spotter) → lock base → raid only when your economy is stable. Rebirth unlocks higher Index tiers later.

When should I merge to higher nuke tiers?

Merge low duplicates quickly to free board space, then push toward 16, 32, and 64 once Spawn Tier and income upgrades are online.

When should I start raiding in progression?

Raid after income upgrades are working and you can lock your base. Early PvP is risky if your board still depends on low-tier spawns.

Is rebirth worth it in Merge a Nuke?

Yes when growth slows — rebirth unlocks higher Index nukes beyond the mid-game cap. Rebirth 3 starts Nuke Mutations. Rebirth 8 is +110% cash (needs Overclocker + Barrier). Rebirth 9 is +120% cash / 5 nukes; Rebirth 10 is +130% / 5 nukes plus Admiral Mutations and a second Mutation slot.

When should I get my first commander?

After Spawn Speed and Spawn Tier are online — Salvager (Common) auto-merges your grid; Spotter (Rare) boosts cash. Full guide: mergeanuke.site/commanders
