Not all mutations are created equal in Storage Hunters: Open World. With 18 mutations ranging from the incredible 50x Secret multiplier down to the value-reducing 0.8x Dirty mutation, knowing which mutations to prioritize can make or break your profits. This Mutation Tier List ranks every mutation from S-Tier (the best) down to C-Tier (the least valuable), helping you make smart decisions during the haul phase and understand the value of every item you find.
How This Tier List Works
Each mutation is evaluated based on three primary criteria:
- Multiplier power - How much the mutation increases (or decreases) an item's base value
- Rarity - How frequently the mutation appears in the game
- Practical impact - How significantly the mutation affects your overall profit per session
The tier ratings align with the game's own internal tier system: S is the highest, followed by A, B, and C. Mutations within the same tier are generally comparable in value, though there are nuanced differences that we highlight in each entry.
For the complete details on any mutation, see our All Mutations Guide.
S-Tier Mutations (The Best in the Game)
S-Tier mutations are the rarest and most valuable mutations in Storage Hunters: Open World. Finding one of these is a highlight of any session, and they should always be your top priority during the haul phase.
Secret - 50x Multiplier
The undisputed king of all mutations. The Secret mutation applies a massive 50x multiplier, making it the single most valuable modifier in the entire game. An item worth 20 cash becomes 1,000 cash. It is Legendary rarity and appears with radiant golden glow and particle effects. For the full deep dive, see our Secret Mutation Guide.
Gold - 4x Multiplier
Gold is the most accessible S-Tier mutation, classified as Rare rather than Legendary. Its 4x multiplier is consistent and reliable, turning a 100-cash item into 400 cash. The Gold mutation appears more frequently than the other S-Tier entries, making it a workhorse for consistent profit.
Diamond - High Multiplier
The Diamond mutation gives items a sparkling crystalline effect and carries a high multiplier. It is Legendary rarity and among the most visually impressive mutations. See our Diamond Mutation Guide for details.
Chrome - High Multiplier
Chrome gives items a reflective mirror finish with a high multiplier. Legendary rarity makes it rare and valuable. The chrome surface effect is distinctive and easily recognizable.
Hologram - High Multiplier
Hologram creates a translucent glowing projection effect on items. The high multiplier and Legendary rarity make it a prized find. The holographic visual is one of the most unique in the game.
Corrupted - High Multiplier
The Corrupted mutation applies a glitched, distorted visual with pixelated static. Despite its damaged appearance, this is a high-value Legendary mutation. The corrupted effect is dramatic and impossible to miss.
Gem - High Multiplier
Gem embeds gemstone-like facets into the item with a shimmering effect. Legendary rarity with a high multiplier. The visual is similar to Diamond but features more pronounced gemstone shapes.
Ancient - High Multiplier
Ancient gives items a weathered, aged texture with rune-like markings. It is Legendary rarity with a high multiplier. The ancient aesthetic gives items a mystical quality that sets them apart.
A-Tier Mutations (Strong but Not Legendary)
A-Tier mutations provide substantial value boosts and appear with enough frequency to meaningfully impact your profits. They are not as rare as S-Tier but still excellent finds.
Void - 35x Multiplier
The Void mutation is the second-highest confirmed multiplier at 35x. With an Epic rarity classification, it appears more frequently than the Legendary mutations. A dark void energy visual effect surrounds affected items. The 35x multiplier makes Void finds incredibly profitable.
Timeless - High Multiplier
Timeless features a clockwork-themed visual with gear and clock elements. Epic rarity gives it moderate frequency, and the high multiplier ensures strong value. The timeless aesthetic is one of the more creative mutations in the game.
Pure - 1.5x Multiplier
Pure may seem modest at 1.5x, but its Uncommon rarity means it appears frequently. The consistent 50% value boost adds up over dozens of items per session. Pure items have a clean bright appearance that is easy to spot.
B-Tier Mutations (Moderate Value)
B-Tier mutations offer decent value boosts. They are common enough to contribute regularly to your income but lack the wow factor of higher tiers.
Silver - 2x Multiplier
Silver doubles an item's base value with a polished metallic sheen. Uncommon rarity means you will see it regularly. While not as exciting as Gold or Void, a consistent 2x boost across many items adds significant profit over time.
Rainbow - TBD Multiplier
The Rainbow mutation creates a color-cycling rainbow gradient on items. Its Epic rarity makes it relatively uncommon, but the multiplier is still being confirmed by the community. The visual effect is stunning, and early data suggests a moderate multiplier.
Antique - Medium Multiplier
Antique gives items a vintage patina with an aged look. Uncommon rarity means it appears often. The medium multiplier provides a modest but consistent value boost. Antique items have a charming aesthetic.
C-Tier Mutations (Low Value or Negative)
C-Tier mutations are the least desirable. Some reduce item value, while others provide minimal benefit. Prioritize these last during the haul phase.
Dirty - 0.8x Multiplier
Dirty is the only mutation that actively reduces item value, applying a 0.8x multiplier. This means items sell for 80% of their base price. The dirt and grime visual effect is unmistakable. Avoid hauling Dirty items when weight capacity is limited.
Tiny - Varies
The Tiny mutation makes items physically smaller. The variable multiplier usually results in low value increases or even slight decreases. Common rarity means you will encounter it frequently, but it rarely impacts your bottom line positively.
Black - Varies
Black applies a dark shadow overlay to items. The variable multiplier tends to produce low values. Common rarity makes it frequent but unremarkable. Black items are darker versions of their normal appearance.
Cobwebbed - Varies
Cobwebbed covers items in a spiderweb pattern overlay. Like the other C-Tier common mutations, the variable multiplier usually results in low value. The cobweb visual is atmospheric but not profitable.

How to Use This Tier List in Gameplay
This tier list directly affects your decision-making in several key moments:
During the Haul Phase
When you open a container and find multiple items, use this tier list to determine your loading order. S-Tier mutation items go first, then A-Tier, then B-Tier. C-Tier items should only be loaded if you have remaining capacity after all higher-tier items are secured.
When Bidding on Containers
Containers from higher areas produce better mutations on average. An A-Tier Shipyard container is more likely to yield S-Tier and A-Tier mutations than a C-Tier Junk Yard container. Factor mutation probabilities into your maximum bid. See our Auction Tips Guide for detailed bidding strategy.
When Deciding What to Sell
If your shop has limited selling space, prioritize displaying high-tier mutation items. A Secret or Diamond mutation item should always have a display slot over a Dirty or Tiny item. The Selling Space gamepass eliminates this concern by providing more slots.
When Evaluating Profit Per Session
Track which mutations you find most frequently and their cumulative impact on your session profit. Even B-Tier mutations like Silver contribute significantly when they appear on many items. The How to Get Rich Fast Guide covers session optimization.

What is the worst mutation in Storage Hunters: Open World? The Dirty mutation is the worst, as it applies a 0.8x multiplier that actively reduces item value. It is the only mutation that decreases an item's selling price below base value.
How many S-Tier mutations are there? There are 8 S-Tier mutations: Secret, Gold, Diamond, Chrome, Hologram, Corrupted, Gem, and Ancient. All provide significant value multipliers.
