USP-S | Serum (Factory New)
The USP-S | Serum (Factory New) is a Classified pistol skin — a bold red digital pattern laid over a bright chrome base. Factory New is the top grade the finish reaches, showing the color at its most saturated and the metallic sheen at its brightest.
Design
Serum is a Valve design that leans hard into a single striking red. The digital pattern is painted with metallic paints of varying reflectivity over a chrome base coat, so different facets catch the light differently and the surface shifts between deep crimson and a brighter, almost liquid shine as the gun moves.
USP-S | Serum (Factory New) Float and Wear
The finish runs a float of 0.00–0.25, which caps it at Field-Tested and leaves no Well-Worn or Battle-Scarred grade at all. Factory New sits at the very bottom of that range, so the red reads deepest, the chrome shine is at full strength, and the slide carries no scuffing whatsoever. This is the grade to chase if you want the color exactly as intended.
USP-S | Serum Rarity
Rarity: Classified — the pink tier, second from the top of the standard weapon grades and one step below Covert. It's a genuinely uncommon grade to pull from a case.
USP-S | Serum Case and Collection
Serum belongs to The Arms Deal 2 Collection and drops from the CS:GO Weapon Case 2, released with The Arms Deal 2 update on November 8, 2013. The Classified tier as a whole unboxes about 3.2% of the time (a rate shared across the tier's skins), and with this early case long gone from the active drop pool, supply is fixed — most copies change hands on the market rather than being unboxed.
USP-S | Serum Patterns
There's no random pattern variation to chase here — the red digital design and chrome base sit the same way on every copy, with no paint seed or "blue gem" lottery. Wear and float are the only things that tell one Serum apart from another.
StatTrak & Souvenir
A StatTrak™ version exists and drops from the same CS:GO Weapon Case 2; it adds a confirmed-kill counter, drops more rarely than the standard skin, and the counter is permanent, carrying over when the item is traded or sold. There's no Souvenir edition — Souvenir weapons come only from Major-tournament packages, and this case was never a Major drop.
USP-S | Serum Price
Factory New sits at the top of the Serum ladder as the cleanest grade the finish offers, a clear step above Minimal Wear. It's a premium USP-S pick without straying into grail money. Available to buy on Skin.Land with instant delivery and no hidden fees.
FAQ
Is Factory New worth it over Minimal Wear?
If the color matters most to you, yes. Factory New shows the red at its deepest and the chrome sheen at full brightness with a spotless slide. Minimal Wear looks close and costs less, so it comes down to whether you want the absolute best condition or the better value.
Why does Serum only go up to Field-Tested?
The finish is float-capped at 0.25, and the game never rolls a copy above that. Well-Worn and Battle-Scarred both need higher float values, so they simply can't exist here — Field-Tested is the most worn grade the skin ever reaches.
Which gloves go with Serum?
Its bold red-on-chrome palette wants a warm, high-contrast loadout, so red or crimson gloves are the natural match — a red pair echoes the finish directly. Black or dark-gunmetal wraps also work if you'd rather let the pistol be the loud element and keep the rest understated.
