UMP-45 | Mudder (Factory New)

The UMP-45 | Mudder (Factory New) is a Consumer Grade SMG finish painted in a gray marbleized pattern. Factory New is the top condition available for it, and this page covers that grade alongside its rarity, collection history, and price.

Design

Mudder applies a marbleized gray paint pattern across the whole body, a simple, utilitarian look rather than anything graphic-heavy. It's a Valve-made finish, keeping to a plain, practical aesthetic rather than a flashy community design.

UMP-45 | Mudder (Factory New) Float and Wear

Float on this finish runs from 0.06 up to 0.80, so it never reaches a true zero float even at its best. Factory New sits at that lowest available point, where the gray marbling shows its full texture and detail with essentially no scuffing. It's as sharp as the Mudder ever looks.

UMP-45 | Mudder Rarity

Rarity: Consumer Grade, the white tier — the most basic rarity band in the game, which keeps this finish priced and supplied like an entry-level pickup.

UMP-45 | Mudder Case and Collection

Mudder is part of The 2018 Inferno Collection, which debuted with the FACEIT 2018 update in September 2018. It doesn't come from a weapon case — the regular version is obtained through trade-ups or as a collection drop, and it also exists as a Souvenir finish handed out in Major-tournament souvenir packages, starting with the London 2018 Inferno Souvenir Package.

UMP-45 | Mudder Patterns

The marbleized paint job is fixed rather than seeded — every copy shows the same pattern regardless of index, so there's no "best roll" to look for. Wear and float are the only things that change the look from copy to copy.

StatTrak & Souvenir

There's no StatTrak version of the Mudder. It does exist as a Souvenir finish, though, first appearing in the London 2018 Inferno Souvenir Package and later showing up in additional Major souvenir packages handed out at subsequent tournaments. The copy on this page is the regular, non-Souvenir finish.

UMP-45 | Mudder Price

Factory New sits at the top of the Mudder's price ladder, though the finish overall is a firmly budget pick regardless of grade. It's an inexpensive way to add a plain, gray-toned skin to a loadout. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

Why doesn't the Mudder come from a case?

It's a collection finish rather than a case skin — the regular version comes through trade-ups or as a collection drop instead of unboxing, while a separate Souvenir version circulates from Major-tournament souvenir packages.

Is there a StatTrak Mudder?

No, this finish was never issued with a StatTrak variant. What it does have is a Souvenir version, first seen in the London 2018 Inferno Souvenir Package and later Major souvenir packages, in addition to the regular finish covered here.

Why is the lowest float on the Mudder 0.06 instead of zero?

Valve sets a minimum possible float per finish, and the Mudder's floor happens to sit at 0.06 rather than 0. That still falls comfortably within the Factory New range, so it doesn't change which grade counts as the cleanest.
