The UMP-45 | Mudder (Field-Tested) is a versatile close-quarters automatic weapon, often considered the misunderstood middle child of the SMG family. Its small magazine may be a drawback, but the skin features a beautifully painted marbleized pattern that enhances its appeal.
The UMP-45 | Mudder was first introduced to CS2 on September 3rd, 2018, as part of the Austin 2025 Inferno Souvenir Package, released alongside the "FACEIT 2018 – Ways to Watch" update.
This skin is designed with a "Hydrographic" finish, predominantly in shades of gray. The unique pattern is achieved by lowering disassembled weapon parts through a floating hydrographic film, ensuring a distinct look that adapts based on its pattern index.
The UMP-45 | Mudder has a float value that ranges from 0.06 to 0.80, making it available in all exteriors. As a Field-Tested skin, its float value specifically falls between 0.15 and 0.37, indicating a moderate level of wear that may slightly affect its appearance.
The price of the UMP-45 | Mudder has shown dynamics in the market, reflecting an increase in value over time due to its popularity and demand compared to other SMG skins. This skin is considered a more common option, yet its unique features contribute to its appeal.
The UMP-45 | Mudder is classified as Consumer Grade rarity, which indicates that it is relatively common among players and has a higher chance of dropping compared to rarer skins.
This skin can be obtained by opening one of the containers, including the Antwerp 2022 Inferno Souvenir Package, Austin 2025 Inferno Souvenir Package, and Berlin 2019 Inferno Souvenir Package. The Consumer Grade rarity also suggests a higher drop chance.
With a popularity rating of 85%, the UMP-45 | Mudder ranks in the top 15% of the most popular items in CS2, reflecting strong daily sales volume and interest among players.
