UMP-45 | K.O. Factory: The Complete Guide

Complete UMP-45 | K.O. Factory CS2 skin guide — explore its history, design, rarity, float range, collection, and availability.

History & Origin

UMP-45 | K.O. Factory released February 4, 2025 as part of the Fever Case.

It's a Counter-Strike 2-native release, launched after Valve's September 2023 relaunch, with no CS:GO history of its own.

It launched as a Classified-tier finish, with both a StatTrak™ and a Souvenir edition.

Design & Finish

As a finish, "K.O. Factory" is applied to the UMP-45 — a slower-firing but more accurate submachine gun option — and carries the pink rarity color every Classified-tier skin shares on the Steam Market and in-game.

That Classified classification places it one tier below the rarest Covert finishes, but above the more common Restricted-and-below skins most loadouts are filled with.

Wear & Float

UMP-45 | K.O. Factory ships in all five wear conditions, from Factory New through Battle-Scarred, across the full 0.00–1.00 float range.

As with every CS2 skin, lower float values look cleaner: Factory New copies (roughly below 0.07 float) show the finish at its sharpest, while Field-Tested and Well-Worn pieces make up the most commonly traded middle ground between mint and heavily worn.

Availability & Drop Mechanics

UMP-45 | K.O. Factory comes from the Fever Case — the Case itself is Armory-exclusive, redeemed with Armory Pass stars rather than a direct weekly drop.

Valve's own published Case odds put a Classified-tier pull like this one at roughly 1 in 94 (1.0667%).

Versions & Variants

There's both a StatTrak™ and a Souvenir edition of this finish, alongside the Normal version — three ways to own the same look, differing only in that badge.

Beyond that, there's no separate "phase" or pattern family tied to this finish in the site's data — it's tracked as a single fixed look across every wear condition it ships in.

Popularity & Community

As a Classified-tier finish, UMP-45 | K.O. Factory sits among the more common pulls from the Fever Case rather than being a chase item — a straightforward, affordable way to add an UMP-45 skin to a loadout or collection.

Its StatTrak™ and Souvenir editions tend to trade at a premium over the Normal version, the same pattern seen across most CS2 skins with that variant available.

Updates & Changes

UMP-45 | K.O. Factory has been part of the Fever Case since February 4, 2025 — a Counter-Strike 2-native release with no CS:GO-era version to compare it to.

Trivia & Related Information

It's one of 3 Classified-tier items in the Fever Case, out of 17 items total.

This is one of 45 UMP-45 skins currently listed on the site, spanning multiple rarity tiers.
