UMP-45 | Delusion

UMP-45 | Delusion is a CS2 SMG skin with bright yellow-green coloring and a screen-printed nautilus motif. Curved lines and shell-like spirals overlap muted purple and dark gray patches across much of the weapon. Its busy appearance suits players who prefer colorful, patterned equipment over restrained finishes. Factory New, Minimal Wear and Field-Tested exteriors are available, alongside StatTrak™ and Souvenir versions.

Description

UMP-45 | Delusion gives the CS2 submachine gun a densely patterned finish built around nautilus imagery. The weapon is suited to close-quarters use, with a small magazine limiting its otherwise versatile role. Delusion combines a Spray-Paint finish classification with a screen-printed design rather than a plain block of color. Yellow-green coverage extends across the receiver, barrel shroud, stock, magazine and grips, making the decoration visible throughout the weapon. Muted purple and dark gray areas provide contrast beneath the brighter surface pattern. The resulting look suits players building a colorful loadout or seeking an SMG with detailed organic shapes. Its place in The Vanguard Collection also gives collection-focused buyers a clear way to organize their purchase. When choosing a copy, buyers can compare the exterior, exact float value and available version rather than judging by the skin name alone.

History and Origin

Delusion debuted on November 11, 2014, as part of the Operation Vanguard update. Steam Workshop community designer Algis created the finish. The skin arrived with the Operation Vanguard Weapon Case, establishing its case-opening acquisition route. It belongs to The Vanguard Collection, linking the weapon finish to that release's collection identity. Valve retired the rare drop pool on December 17, 2025. As of October 9, 2026, the Operation Vanguard Weapon Case no longer drops, so new cases do not enter circulation through drops. Existing cases can still be purchased on the market and opened, keeping the original acquisition route usable despite that retirement. Individual copies can also be obtained through the Steam Community Market or player-to-player trades without opening a case.

Finish Style

Delusion uses the Spray-Paint finish style, with screen-printed nautilus imagery supplying its recognizable detail. Bright yellow-green covers most of the visible weapon, creating a vivid base for the overlapping decoration. Muted purple and dark gray patches sit beneath that brighter coloring and break up the surface. Closely spaced curved lines form shell-like spirals rather than a simple geometric stripe pattern. These lines are particularly clear on the long magazine, vertical foregrip and pistol grip. The receiver and barrel shroud carry the same layered combination of color and curved markings. Even the open-frame stock receives the yellow-green and purple treatment, while the trigger and recessed areas remain dark. Together, the irregular patches and repeated curves create a busy visual texture across nearly every visible surface.

Float Value

UMP-45 | Delusion has a float range of 0.06 to 0.35, which buyers can check when comparing individual listings. Its available exteriors are Factory New, Minimal Wear and Field-Tested. StatTrak and Souvenir versions are also available, but those version labels are separate from the float value and exterior condition.

Rarity and Popularity

Delusion is a Mil-Spec Grade skin, with rarity describing its item grade rather than its cosmetic condition. Its stated chance from the Operation Vanguard Weapon Case is 15.98%, so opening that case does not guarantee this particular result. Professional players ScreaM, Xizt and Dycha have owned the skin, providing concrete ownership examples without establishing broader trading demand.

Why it’s Popular:

• Bright yellow-green coloring suits colorful SMG loadouts

• Nautilus spirals add detail across the magazine and grips

• Purple and dark gray patches contrast with the brighter finish

• StatTrak and Souvenir versions offer additional collecting choices

Price Range

The live UMP-45 | Delusion price range is $0.43 to $50.00. These bounds cover the whole skin and should not be treated as fixed prices for particular exteriors or versions. Compare Factory New, Minimal Wear and Field-Tested listings within the exterior being considered, then check each copy's exact float. Standard, StatTrak and Souvenir listings should also be distinguished when evaluating the CS2 skin price. An item preview helps buyers assess the visible finish alongside the listing details before deciding which copy to buy.

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 Operation Vanguard Weapon Case

Opening the Operation Vanguard Weapon Case offers a chance to obtain Delusion, with a stated probability of 15.98%. The case no longer drops, but existing cases can still be bought on the market and opened. This remains a chance-based route rather than a way to select a particular Delusion listing.

3. Buy on the Steam Community Market

UMP-45 | Delusion can be bought directly on the Steam Community Market without opening its case. Buyers should check the exterior and whether the listing is standard, StatTrak or Souvenir. Reviewing the exact float and item preview helps distinguish individual copies before purchase.

4. Trade with Other Players

Players can obtain Delusion by trading with another player who owns a copy. The offered item should be checked for its exterior, exact float and version before the exchange is accepted. Trading provides a route to a selected copy, unlike the uncertain result of opening the Operation Vanguard Weapon Case.

Trading and Investment Considerations

The retired case receives no new drops, although opening existing cases can still add Delusion copies to circulation while reducing remaining case supply. Professional ownership supports some player interest, but there is insufficient evidence to establish sustained demand or a price trend. Players looking to buy, sell or trade should compare matching exteriors and versions rather than treating every Delusion listing as equivalent.

Reasons it Holds Value

• Retired case supply limits future case-sourced additions

• Documented ownership by ScreaM, Xizt and Dycha

• StatTrak and Souvenir options expand collecting choices

• Distinctive nautilus artwork gives the finish a clear identity

Delusion receives a medium investment rating, supported by its retired case source and documented professional ownership. Its relatively accessible price level makes it approachable, but the 15.98% case chance limits the scarcity argument. The main risk is uncertain sustained demand, so restricted case supply alone should not be treated as a promise of appreciation.
