Destroy a Vault Beginner Guide: Tanks, Gold, the Smelter and Upgrades

Destroy a Vault is a Roblox incremental simulator by LoopForge Studios. It was created in July 2026, has passed 11 million visits and shows about 26,000 players online right now, with a 96 percent like ratio. The loop is easy to learn, but it is easy to waste money in the first hour. This guide explains the loop, the three currencies and the upgrade order that two independent guides recommend. Both guides date from October, so check prices in the game if they look different.

## The core loop The game's own description sums it up: roll for rare tanks, blast the vault until it breaks open, smelt the gold into cash, then upgrade your army and move on to stronger vaults. In practice the steps are:

1. Pull the lever at the roll station to roll a tank.
2. Buy the tank with Cash and place it on an open slot in your base. Bloxodes stresses that a rolled robot earns nothing until you place it.
3. Placed tanks fire at the vault by themselves and drain its health.
4. A broken vault drops gold blocks onto the collector platform.
5. Carry the gold to the smelting furnace to turn it into Cash.
6. Spend the Cash on more tanks, more slots, upgrades and stronger vaults.

The game description also says your tanks keep earning gold while you are offline, as long as they are already placed.

## The three currencies - Gold: dropped by broken vaults. You cannot spend it until you smelt it. - Cash: made by smelting gold. It buys tanks, slots and upgrades. - Gems: earned in the game or from codes. According to AllThings.how, they are spent on Mutation Cores, which you put on a placed tank to multiply its damage. Bloxodes says the shop for these is called the Market. The two guides name it differently, so look for the shop with the cores.

## Upgrades in a sensible order Both guides agree that damage comes first. Bloxodes lists this order: tank damage, then battery, then luck once the attack loop works, then more roll spots when Cash is flowing, and last the vault gold value, which is expensive early on. AllThings.how gives actual prices for the gold value upgrade: 1x to 2x costs 1.5K, 2x to 3x costs 1.2M, 3x to 4x costs 25M and 4x to 5x costs 1.14B. It also advises buying the 1.5K upgrade early, since it is cheap for what it does.

## Mutation Cores, fusing and the index AllThings.how lists four Mutation Cores: Iron, Flame, Frost and Lightning. The first three give 1.5x, 1.75x and 2x damage and cost 5K, 25K and 150K Gems. Lightning costs 400K Gems, and the guide does not give its multiplier. Put cores on your best tank.

Fusing four tanks of the same model creates one stronger MEGA version. Both guides say the Fuse Machine comes after you expand to the second area, which costs 700K according to AllThings.how, and Bloxodes adds that a fused tank cannot be fused again. Collecting new tanks also adds permanent luck: AllThings.how says every 5 units in the index give +2.5 percent.

## Codes The game description lists a few codes, but codes in this game change quickly. Several old ones are already expired, so use our Destroy a Vault codes page for the current status.

## Quick tips - Do not rush a Lucky Roll. Save it until your luck is higher. - Keep duplicate tanks for fusing. - Spend on damage before cosmetics. - Walk the gold to the furnace often, because gold is worth nothing until it is smelted.

What we could not confirm: the rarity names of the tanks themselves and the exact odds of each roll. The guides do not list them, so we do not either.
