How to Spend Code Rewards on Commanders
Convert rewards into income first
Merge the free nukes from codes into higher tiers before spending on rolls — a stronger grid funds commander unlocks continuously instead of once.
Save for a cash-multiplier commander
The community-ranked best target is the highest-rarity cash-multiplier commander you can afford. It scales every nuke on your grid and compounds offline earnings.
Raiders: consider the Spotter
If you raid actively, the Rare Spotter (boosts launched-missile damage) is the strongest attack pick and cheaper to reach than a Legendary.
Which Commander to Unlock First
Offline / AFK farming
Highest cash-multiplier Legendary you can unlock
A cash multiplier scales every nuke on your grid, so it compounds your offline earnings more than any other effect.
Fast early progression
Spawn-boost commander
More spawns per minute means more duplicates to merge, getting you to mid-tier nukes faster before switching to a cash commander.
Active raiding
Raid-boost commander
If you raid often, the extra steal amount can outpace pure passive bonuses — pair it with B-tier or higher nukes.
Commander details are community estimates from the new Commander Update and pending in-game verification. Named commanders are sourced from community guides and may be renamed or rebalanced in Friday patches.
Frequently Asked Questions
Are there separate Merge a Nuke commanders codes?
No. There is no commander-only code list — Merge a Nuke uses one shared code system. The regular codes (ATOMIC, UPDATE2, BOOM) give cash and nukes you can put toward unlocking and rolling commanders.
Which code unlocks commanders fastest?
ATOMIC ($10,000 cash + 20 nukes) is currently the biggest single boost. Redeem every active code, merge the free nukes up for passive income, and spend the proceeds in the Commanders menu.
Do codes give free commander rolls?
Current verified codes reward cash and nukes rather than direct commander rolls. Reward types rotate with Friday patches, so redeem every new code — commander-related rewards may appear in future drops.
Which commander should I unlock first with code rewards?
Aim for the highest-rarity cash-multiplier commander you can afford — it scales every nuke on your grid and compounds offline earnings. Raiders can prioritize the Rare Spotter for launched-missile damage instead.
How do I redeem commander codes?
All codes redeem the same way: open the Store on the left menu, scroll to the code box, enter the code exactly (case-sensitive), and click Redeem. Then open the Commanders menu to spend your rewards.
