UMP-45 | Mudder (Minimal Wear)

The UMP-45 | Mudder is a CS2 weapon skin based on the CS:GO (legacy) model. It’s part of the 2018 Inferno Collection, tying the design to the era when Counter-Strike weapon finishes increasingly leaned into themed textures and battlefield-inspired visuals. With a wide float range of 0.06 to 0.8, this skin can appear clean to heavily used depending on wear condition.

As a Consumer Grade item, Mudder is generally considered accessible compared to rare drops. While exact drop chances are not publicly guaranteed for individual skins, Consumer Grade items are typically among the more attainable rarities through case openings and collection access. That said, specific inventory availability can vary by region and platform economy.

The UMP-45 | Mudder is available in multiple wear categories: Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred. StatTrak is not available for this skin, but Souvenir is available, making it a popular choice for players who collect event-linked weapon finishes. The paint index is 90, which helps identify the exact pattern variant used by this skin.

Visually, the “Mudder” finish delivers a gritty, camouflage-like look designed to blend with worn, urban environments. Because the float range spans from slightly worn to very battle-scarred conditions, the surface appearance can shift noticeably—patina and wear effects become more pronounced at higher float values, giving collectors more variation to choose from.

You can obtain UMP-45 | Mudder through its presence in multiple event souvenir packages and collections. It’s found in the 2018 Inferno Collection, and also appears in souvenir containers including London 2018 Inferno, Katowice 2019 Inferno, Berlin 2019 Inferno, Stockholm 2021 Inferno, Antwerp 2022 Inferno, Rio 2022 Inferno, Paris 2023 Inferno, Copenhagen 2024 Inferno, Shanghai 2024 Inferno, Austin 2025 Inferno, and Budapest 2025 Inferno—including both standard and “Highlight” versions for the latest listed events.

In the community, Mudder is appreciated for its grounded, non-flashy aesthetic that fits well into practical loadouts. Its Consumer Grade rarity and broad wear availability make it a solid everyday UMP-45 choice, while the Souvenir variant adds collectible value for fans of Inferno-themed event drops.
