- S-tier robot army: fill every placement slot with your highest-rarity upgraded tanks

- Gems strategy: save them for Mutation Cores instead of routine spending
Destroy a Vault Endgame Overview
The endgame in Destroy a Vault begins once your robot army can break stronger vaults efficiently and you unlock the content introduced with the BOSSES update. At this stage, the core loop — roll rare robot tanks, blast the vault until it breaks open, smelt Gold into Cash, and upgrade your army — shifts toward high-durability targets like Boss Vault Raids.
The main endgame progression paths compare as follows:
| Endgame Path | Target | Key Requirement | Reward Focus |
|---|---|---|---|
| Stronger Vaults | High-durability standard vaults | Upgraded mid-to-high rarity army | Higher Gold per break |
| Boss Vault Raids | Boss-level vault targets | Fully developed, high-rarity army | Boss-level Gold payouts |
| Mutation Progression | Robot mutation upgrades | Gems for Mutation Cores | Long-term army power |
| Offline Farming | Deployed army | Robots placed before logout | Passive Gold accumulation |
Boss Vault Raids
- Highest difficulty vault content
- Requires maxed deployment slots
- Best Gold potential per attack
Mutation Cores
- Purchased with Gems
- Powers robot mutation progression
- Best used on keepers
Offline Earnings
- Robots earn Gold while offline
- Fund future rolls and upgrades
- Core idle mechanic
Treat the BOSSES update as the real endgame dividing line. Before committing Gems or heavy Cash investment, confirm your active army can already clear your current strongest vault efficiently — otherwise, upgrades deliver more value than boss attempts.
Endgame Vault Targets Compared
Endgame vault selection is about matching your army's damage output to vault durability. Attacking a vault your army cannot break quickly wastes time that stronger farming targets would reward better.
| Vault Level | Unlock Condition | Durability | Reward | Recommended Setup |
|---|---|---|---|---|
| Standard Vaults | Starting content | Baseline | Gold | Fill all slots with best robots |
| Stronger Vaults | Progression unlock | Higher than baseline | Higher Gold potential | High-rarity robots + upgrades |
| Boss Vault Raids | BOSSES update | Boss-level | Gold from boss completion | Highest-rarity, most-upgraded robots |
Boss Vault Raids punish underdeveloped armies. If your vault break times are slowing down, invest Cash into army upgrades and attack slots before pushing into boss content.
Step-by-Step Endgame Progression
Follow this order to reach the Destroy a Vault endgame without wasting resources:
Complete the Base Loop
Roll robot tanks, fill your army slots, break your current vault, and smelt Gold into Cash until upgrades slow down.
Upgrade the Army
Replace low-rarity tanks with higher-rarity rolls and upgrade your core attackers to raise damage output.
Expand Attack Slots
Increase the number of robots that can participate in attacks so each vault breaks faster and Gold generation accelerates.
Unlock Stronger Vaults
Move to stronger vaults once your army handles the current tier efficiently, keeping Gold income rising.
Expand Your Base
Invest in base space to support a larger setup and scale long-term production.
Prepare for Boss Vault Raids
Save Gems for Mutation Cores, max out deployment, and use your best robots against Boss Vault Raid targets.
Always leave your strongest robots deployed before logging off. Deployed robots continue earning Gold automatically, so offline sessions fund your next upgrade cycle.
Endgame Resource Management
The endgame economy runs on a clear resource chain: Gold from vault breaks and offline earnings, smelted into Cash for upgrades, with Gems reserved for premium progression.
| Resource | Source | Role | Endgame Priority |
|---|---|---|---|
| Gold | Vault breaks, offline robot earnings | Smelt into Cash | Attack the strongest vault you clear efficiently |
| Cash | Smelting Gold | Army, slots, base upgrades | Prioritize attack capability upgrades |
| Gems | Premium / codes | Mutation Cores | Save for high-value premium purchases |
| Mutation Cores | Bought with Gems | Mutation progression | Use only on long-term army keepers |
Avoid routine Gem spending. Mutation Cores are the standout premium purchase in the endgame, and applying them to robots that will stay in your lineup long-term delivers the best value.
Endgame Robot Priorities
Endgame robot decisions follow rarity, damage, and Gold efficiency. Use this ranking logic when deciding what to keep, upgrade, or replace:
| Tier | Stage | Rarity Focus | Action |
|---|---|---|---|
| S Tier | Late game | Highest rarities | Keep, upgrade, and build Boss Raid lineup around them |
| A Tier | Mid game | High rarity | Core army members until S-tier replacements arrive |
| B Tier | Early game | Common / lower rarity | Fill slots early, phase out gradually |
| C Tier | Replacement | Duplicates, outdated | Replace without weakening the active army |
Endgame Milestones:
- Fill every placement slot with high-rarity robots
- Unlock and clear stronger vaults efficiently
- Build a Boss Vault Raid-ready army
- Save Gems and purchase Mutation Cores
- Keep robots deployed for offline Gold income
Never strip your active army to rush an upgrade. Replace C-tier robots gradually so your damage output and offline Gold earnings never dip during the transition.
FAQ
Q: What counts as the Destroy a Vault endgame?
The endgame starts once your army breaks stronger vaults efficiently and you can access Boss Vault Raids and Mutation Cores introduced in the BOSSES update. At that point, progression focuses on high-rarity robots, maximum deployment, and premium mutation upgrades.
Q: How do offline earnings work in the endgame?
Deployed robots continue earning Gold automatically while you are offline. Log back in regularly to collect the accumulated Gold, smelt it into Cash, and fund the next round of army or base upgrades.
Q: Should I spend Gems on Mutation Cores or regular upgrades?
Save Gems for Mutation Cores. Cash handles routine army, slot, and base upgrades, while Mutation Cores are the premium path that strengthens robots expected to remain in your long-term attack army.
Q: When should I attempt Boss Vault Raids?
Attempt boss raids only after your army clears your strongest standard vault quickly. Use your highest-rarity, most-upgraded robots with as many placement slots filled as possible for the best results.
