UMP-45 | Фабрика нокаутов

Origin Story

The UMP-45 | K.O. Factory, released on April 1, 2025, as part of the Spring Forward update, draws its inspiration from classic animation cartoons. Its custom paint job features a design reminiscent of old-school animated shorts. The flavor text, "Swing and a miss!", further hints at a playful, possibly boxing-themed, aesthetic. This skin was introduced within The Fever Collection.

Drop Chance

UMP-45 | K.O. Factory is Classified, a Pink-tier skin, rare with strong collector demand. From the Fever Case: approximately 1.07% per opening (roughly 1 in 94). The 3.2% Classified tier rate is split across 3 Classified skins in the case. StatTrak versions drop at ~0.11% from the Fever Case (about 1 in 937). These per-skin odds assume equal weighting within tier — Valve publishes tier rates but doesn't formally confirm even distribution across skins in a tier.

Skin Condition

Float range 0 to 1. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($19.15): The cartoon-style artwork maintains maximum color vibrancy and definition, with minimal wear on edges.
• Minimal Wear ($8.02): Very slight softening or tiny scratches appear on high-contact edges like the front barrel shroud or stock corners, usually only visible upon close inspection.
• Field-Tested ($6.07): Noticeable edge wear and small patches where underlying material shows are common, particularly on the front and side of the receiver and the magazine.
• Well-Worn ($5.55): Expect heavier wear on edges and more extensive fading across the body, with details of the cartoon artwork appearing washed or partially obscured.
• Battle-Scarred ($5.21): Significant fading and large patches of exposed base material are typical, often causing the cartoon artwork to appear eroded or heavily muted.

Sticker Compatibility

The UMP-45 offers multiple sticker slots, typically on the receiver, a front-side area, and sometimes the magazine. Given the "old animation cartoons" theme, bright, cartoonish, or comic-style stickers may visually complement the design. If the skin's palette is more muted, black-white, sepia, or pastel stickers could create a cohesive retro look.
