USP-S | Serum

USP-S | Serum is a CS2 pistol skin for the Counter-Terrorist side, combining dark colors with reflective metallic patches. Its digital pattern covers the suppressor, slide and grip in black, dark gray and deep red. The busy finish suits dark loadouts with contrasting metallic accents. Factory New, Minimal Wear and Field-Tested exteriors are available, alongside StatTrak™ and Souvenir versions.

Description

USP-S | Serum gives the Counter-Terrorist pistol a dark, patterned finish with flashes of reflective silver. Its Anodized Multicolored finish combines a digital design with metallic paint over a chrome base. Rather than concentrating decoration on the slide, the pattern extends across the suppressor and grip. The weapon itself has a detachable suppressor that reduces recoil and dampens firing noise. Deep red patches provide color without replacing the finish's predominantly dark appearance. This combination suits players seeking a detailed pistol rather than a plain or uniformly colored design. Buyers can choose a standard copy or consider the supported StatTrak and Souvenir alternatives. When comparing listings to buy, sell or trade, the exterior, exact float and version help distinguish otherwise similar-looking copies.

History and Origin

USP-S | Serum debuted in CS:GO on November 8, 2013, with the Arms Deal 2 update. Its original case was the CS:GO Weapon Case 2, which remains its associated opening route. Valve created the finish, rather than a community designer. The skin belongs to The Arms Deal 2 Collection, which also provides its collection-based trade-up route. Valve retired the rare drop pool on December 17, 2025, and the case no longer drops as of October 9, 2026. Existing cases can still be purchased on the market and opened, keeping that acquisition method available without new case drops. Today, direct marketplace purchases and player trades offer alternatives to obtaining the skin through its original container.

Finish Style

Serum uses an Anodized Multicolored finish with a digital pattern across most visible surfaces. Metallic paint sits over a chrome foundation, giving different patches contrasting levels of reflectivity. Dark gray and black form much of the background, interrupted by deep red areas and reflective silver. Irregular angular blocks and broken bands spread across the suppressor, slide and grip. These shapes give the design a fragmented appearance rather than a continuous stripe or smooth color transition. Bright highlights are visible around the muzzle rim, trigger guard and ridged front of the grip. Fine serrations at the rear of the slide remain visible beside small markings. The overall visual character is busy and metallic, with dark sections framing the brighter patches throughout the pistol.

Float Value

USP-S | Serum has a float range of 0.00 to 0.25. Its available exteriors are Factory New, Minimal Wear and Field-Tested, with no Well-Worn or Battle-Scarred copies. StatTrak and Souvenir versions also exist, but version selection is separate from the float value and exterior condition of an individual copy.

Rarity and Popularity

USP-S | Serum is a Classified pistol skin from The Arms Deal 2 Collection. Its stated chance from the CS:GO Weapon Case 2 is 1.6%, making a case opening an uncertain acquisition route. AdreN, boltz and isak are documented professional owners, providing concrete ownership evidence without establishing broader market demand.

Why it’s Popular:

• Dark red and black styling with reflective silver contrast

• Digital pattern extends across the pistol and suppressor

• Factory New availability within a limited float range

• StatTrak and Souvenir options for different collecting preferences

Price Range

The live USP-S | Serum price range is $48.44 to $132.56. These bounds cover the whole skin, rather than identifying a particular exterior or version. Compare Factory New, Minimal Wear and Field-Tested listings according to their actual float values. Standard, StatTrak and Souvenir copies should also be checked separately instead of assuming their asking prices are interchangeable. For a useful CS2 skin price comparison, match the version and exterior before examining the exact float and visible condition.

How to Obtain

1. Buy Directly through Eneba Skins

One of the fastest and most straightforward options is to purchase skins directly through Eneba Skins. You can browse available CS2 skins, compare prices, and choose the items that best fit your budget.

2. Open the CS:GO Weapon Case 2

Open the CS:GO Weapon Case 2 for a chance to receive USP-S | Serum. The case no longer drops, but existing containers can still be bought on the market and opened. The skin's stated opening chance is 1.6%, so purchasing a case does not ensure this result.

3. Trade Up Contracts

A Trade Up Contract can exchange 10 Restricted skins from The Arms Deal 2 Collection for 1 Classified skin from that collection. USP-S | Serum is a possible result, not a guaranteed outcome. The result is random among the collection's Classified skins.

4. Buy on the Steam Community Market

The Steam Community Market offers a direct purchase route for USP-S | Serum without relying on a random case or contract result. Check each listing's exterior, float and version before choosing a copy.

5. Trade with Other Players

Player-to-player trades provide another way to acquire USP-S | Serum by exchanging items with another player. Confirm the exact skin, exterior, float and version in the offer before agreeing to the exchange.

Trading and Investment Considerations

Retirement limits replenishment of the original case, although trade-up contracts remain another source of Serum copies. Professional ownership supports its visibility but does not establish sustained demand or easy resale. When comparing buy, sell or trade offers, match the exterior, float and version rather than treating every available copy as equivalent.

Reasons it Holds Value

• No new drops replenish its original case

• Documented ownership by professional players

• Valve-created finish from The Arms Deal 2 Collection

• StatTrak and Souvenir versions offer distinct collecting options

USP-S | Serum receives a medium investment rating, supported by its retired case source and documented professional ownership. Trade-ups can still add copies, so declining case supply does not make the skin's total supply fixed. The main risk is overestimating the effect of case retirement while future demand and resale speed remain uncertain.
