UMP-45

The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. It has been painted in a marbleized pattern.

The UMP-45 | Mudder was first introduced to CS2 7 years ago, on September 3rd, 2018. It was released as part of the Budapest 2025 Inferno Souvenir Package, alongside the "FACEIT 2018 – Ways to Watch" update.

The UMP-45 | Mudder can be obtained by opening one of the 11 containers that contain the skin. This includes the Antwerp 2022 Inferno Souvenir Package, Austin 2025 Inferno Souvenir Package and Berlin 2019 Inferno Souvenir Package container. The skin is also part of the The 2018 Inferno Collection.

With a popularity of 75%, the UMP-45 | Mudder is currently in the top 25% of the most popular items in CS2. This popularity measurement is based on the daily sales volume and the price of the skin.

The UMP-45 | Mudder is one of 283 other SMG skins. The rarity of the skin is Consumer Grade, which makes the Mudder a pretty common occurrence in the game.

With a price range between $0.00 and $0.00, the UMP-45 | Mudder is a pretty affordable skin. Fortunately, it's currently widely available and can be purchased on multiple different markets.

The float value of the UMP-45 | Mudder ranges from 0.06 to 0.80, which makes the skin available in all exteriors. For each exterior, there also exists a Souvenir version for the Mudder.

This UMP-45 has been painted in a "Hydrographic" style, with the Mudder finish. Disassembled weapon parts are lowered through a floating hydrographic film on the surface of a water tank. The film adheres to the primed weapon parts, covering the surface with a pattern. That said, this particular skin has been mostly painted in shades of gray. The look of the Mudder finish is affected by its pattern index. The skin uses the old legacy model.
