Understanding the Vault Attack Loop
In Destroy a Vault, a Roblox simulation by LoopForge Studios, your entire progression revolves around one repeating cycle: build a robot army, blast the vault until it breaks open, collect the Gold it drops, and smelt that Gold into Cash. Cash then funds stronger robots, more attack slots, and base expansion, which lets you unlock stronger vaults. Every decision in this guide flows from that loop.
| Stage | Action | Resource Gained | Resource Spent |
|---|---|---|---|
| Roll | Spin for robot tanks of different rarities | New robots | Cash / free rolls |
| Attack | Deploy army against the vault | Gold (on break) | Attack time |
| Smelt | Convert Gold into Cash | Cash | Gold |
| Upgrade | Buy army, slots, and base upgrades | Higher income | Cash |
| Unlock | Move to stronger vaults | Better Gold per break | Army strength |
Always attack the strongest vault your army can break efficiently. Farming a vault far below your army's power wastes attack time you could spend on higher Gold rewards.
Building Your Robot Army
Robots (robot tanks) are obtained through random rolls and sorted by rarity. Early on, an army of common robots that fills every placement slot beats a half-empty lineup with one decent pull. Replace the weakest active member whenever a higher-rarity robot arrives.
Early Game
- Priority: Fill all slots
- Any rarity is usable
- Focus rolls on volume, not perfection
Mid Game
- Priority: Rarity upgrades
- Replace weakest actives first
- Invest Cash in army strength
Late Game
- Priority: Boss-ready lineup
- Mutation Cores on keepers
- Maximum deployment for Boss Vault Raids
- Maximum practical deployment for Boss Vault Raids
| Tier | Stage | Rarity Focus | Keep or Replace |
|---|---|---|---|
| S | Late Game | Highest rarities | Keep and upgrade |
| A | Mid Game | High rarity | Keep until better arrives |
| B | Early Game | Common / low | Keep until army is full |
| C | Replacement | Duplicates, outdated | Replace gradually |
Do not bench robots just because they are common. An active B-tier robot earning Gold beats a benchwarmer S-tier pull doing nothing.
Step-by-Step Vault Attack Walkthrough
Follow this sequence each session to keep the Gold-to-Cash chain running smoothly.
Log In and Collect Offline Gold
Your deployed robots earned Gold while you were offline. Collect it before doing anything else so the smelter stays busy.
Redeem Available Codes
Open Settings, select the codes tab, and enter any active code (RELEASE and UPDATE are confirmed active as of October 2026) for free Cash and Gems.
Roll and Update the Army
Spend surplus resources on rolls. Swap any new higher-rarity robot into your active lineup, replacing the weakest member.
Blast the Vault
Send your full army at the strongest vault you can break efficiently. Let the attack run until the vault breaks open.
Smelt Gold into Cash
Convert collected Gold into Cash immediately so it can fund your next upgrade instead of sitting idle.
Reinvest and Re-Deploy
Buy army or attack-slot upgrades, keep your best robots deployed, then log off to bank offline earnings.
A five-minute login cycle — collect, smelt, roll, upgrade, re-deploy — is enough to keep progression moving between longer play sessions.
Upgrade Priorities and Resource Spending
New players often spread Cash too thin across base cosmetics and low-impact upgrades. The table below ranks where your resources deliver the best returns.
| Upgrade Type | Priority | Why It Matters | Best Stage |
|---|---|---|---|
| Army strength | Highest | More damage breaks vaults faster | All stages |
| Attack slots | High | More robots attacking per run | Early to mid |
| Placement slots | High | Larger active army overall | Early to mid |
| Base expansion | Medium | Room to scale long-term | Mid game |
| Boss preparation | Situational | Boss Vault Raid readiness | Late game |
| Resource | Source | Main Use | Spending Rule |
|---|---|---|---|
| Gold | Vault breaks, offline earnings | Smelt into Cash | Smelt regularly, do not hoard |
| Cash | Smelting Gold | Army, slots, base | Attack capability first |
| Gems | Codes / premium | Mutation Cores | Save for high-value purchases |
| Mutation Cores | Bought with Gems | Robot mutation progression | Use on long-term keepers only |
Gems belong in your premium budget. Spending them on routine army costs instead of saving for Mutation Cores slows down late-game Boss Vault Raid preparation.
Progression Checklist and Boss Raids
Vault Progression Milestones:
- Fill every placement slot with an active robot
- Smelt Gold into Cash immediately after each vault break
- Unlock the next stronger vault tier
- Build a high-rarity active army of A-tier or better
- Save Gems for Mutation Cores from the BOSSES update
- Attempt your first Boss Vault Raid with a fully upgraded army
The BOSSES update introduced Boss Vault Raids, the highest-difficulty vault targets, along with Mutation Cores as a premium progression path. Before attempting a raid, your army should already break the strongest standard vaults quickly — a raid that stalls wastes attack time your regular loop could be converting into Cash.
If your army cannot destroy the strongest regular vault without long delays, you are not ready for a Boss Vault Raid. Reinvest in army strength and slots first.
FAQ
Q: How does the Destroy a Vault core loop actually work?
Roll for rare robot tanks, blast the vault until it breaks open, collect the Gold, smelt it into Cash, and spend that Cash upgrading your army and base so you can unlock stronger vaults. Robots also keep earning Gold while you are offline.
Q: What should I upgrade first in Destroy a Vault?
Army strength and attack slots deliver the best early returns because they directly increase how fast you break vaults. Base expansion is a mid-game purchase once your income supports it.
Q: How do offline earnings work?
Deployed robots automatically generate Gold while you are away from the game. Log in regularly to collect it, smelt it into Cash, and reinvest before logging off so the cycle continues.
Q: What are Gems used for?
Gems are the premium currency used mainly to purchase Mutation Cores introduced in the BOSSES update. Save them for these high-value purchases rather than routine army spending.
