Start on your base and open the Upgrade menu
Spawn rate is controlled from one place. On your island the green UPGRADE button sits in the top bar next to the red Locked shield timer — the video taps it to open the panel that governs how many nukes appear. Your nukes are already ticking cash on their pads while you do this.

Read the three upgrade rows: Spawn Tier, Max Spawn, Lock Base
The Upgrade panel lists exactly three rows — Spawn Tier, Max Spawn and Lock Base — each with a level, a bracketed value and a cash price. In the video's example they read Spawn Tier Level 10 (512) for $54.65M, Max Spawn Level 15 (19) for $18.74M and Lock Base Level 12 (06:30) for $8.69M. Max Spawn's bracketed number is how many nukes can be on your base at once.

Buy up Max Spawn to spawn more nukes at once
The creator's whole point is Max Spawn — 'click on maximum spawn'. After spending cash the same menu now reads Spawn Tier Level 11 (1024) and Max Spawn Level 17 (21), so the base is allowed to hold two more nukes than before. Raising Max Spawn is the direct way to have more nukes spawning on your pads.

Every spawned nuke keeps earning cash
More nukes means more income lines. The shot shows a full field of blue and pink missiles each popping its own cash value — +$1.02K, +$512 and similar — under a Cash total of $120.91M. Each nuke you manage to spawn adds another ticking income source.

Fill every launch pad across the island
From above you can see the payoff of a high Max Spawn: the whole island is carpeted with nukes on pads inside the blue Locked shield dome, Cash at $121.69M. Keeping the base locked while the pads fill means nobody raids the pile you are spawning.

Higher Spawn Tier spawns more valuable nukes
Spawn Tier sets the tier of the nukes that appear — in the video it climbs from Level 10 (512) to Level 11 (1024). The base here shows a mix of blue and darker green higher-tier missiles, so raising Spawn Tier changes what spawns, not just how much.

Balance Max Spawn and Spawn Tier together
The strongest spawn setup raises both levers: enough Max Spawn to fill the pads and a high enough Spawn Tier that those pads hold valuable nukes. This frame shows a packed arsenal of blue, pink and green missiles at Cash $17.55M with the base still on its Locked timer.

Optional Robux shortcut: the x2 Spawn gamepass
The Exclusive Store's GAMEPASSES tab sells an 'x2 Spawn' pass — 'Nukes spawn twice as fast!' for 129 Robux — plus 'Auto Merge Nukes!' for 199 Robux and 'Quicker Lock Cooldown' for 79 Robux. These are paid shortcuts; the Max Spawn and Spawn Tier upgrades above are the free path.

What each upgrade actually changes
Spawn rate is two independent dials. Max Spawn sets how many nukes can exist on your pads at once (the bracketed number — 19 then 21 in the video), while Spawn Tier sets the value of each nuke that appears (512 then 1024). Lock Base does not spawn anything, but it protects the pile long enough for it to be worth something.
- How to lock your base — Extend the shield that guards your spawned nukes.
- How to get mutations — Mutations change what your nukes do once they are spawning.
Keep growing your base
Once the pads are full, point that extra output at the rest of your progression.
- How to get more cash fast — Turn all those spawned nukes into income.
- All game passes — See what x2 Spawn and Auto Merge are worth.
- How to level up fast — Convert nukes into XP and higher tiers.
Frequently Asked Questions
What upgrade increases how many nukes spawn in Merge a Nuke?
Max Spawn. In the video's Upgrade menu the bracketed number after Max Spawn is how many nukes can be on your base at once — it goes from Level 15 (19) to Level 17 (21) after buying, so the base spawns two more nukes simultaneously.
What does Spawn Tier do?
Spawn Tier sets the tier (value) of the nukes that appear. The video raises it from Level 10 (512) to Level 11 (1024), so each newly spawned nuke is a higher, more valuable tier. It changes what spawns, not how many.
Is the x2 Spawn gamepass worth buying?
The Exclusive Store lists x2 Spawn at 129 Robux with the description 'Nukes spawn twice as fast!'. It is a paid shortcut to spawn speed; you can reach the same effect for free by raising Max Spawn and Spawn Tier, so treat it as optional.
Why should I lock my base while spawning nukes?
The Lock Base row (Level 12 = 06:30 in the video) sets how long your shield holds. A locked base stops other players raiding the pile of nukes you have just spawned, so the pads stay full and keep earning.
Do more spawned nukes actually mean more cash?
Yes — each nuke on a launch pad ticks its own cash value at the same time (the video shows fields of nukes popping +$1.02K and +$512 together). More nukes on the pads is more parallel income streams.
Can I spawn more nukes without spending Robux?
Yes. Max Spawn and Spawn Tier are bought with in-game cash from the UPGRADE menu. The x2 Spawn gamepass is only a Robux shortcut on top of that free path.
