UMP-45 | Mudder (Field-Tested)

Skin overview

This UMP-45 finish is built around a muddy, marbled camouflage that suits worn conditions better than most bright skins. In Field-Tested the first scuffs on edges and raised parts blend into the brown blotches and read as natural weathering. The overall tan look stays intact at normal viewing distance.

Item type: smg. Consumer Grade is the lowest tier of the rarity scale: the most common skins, most often used in trade-up contracts.

Hydrographic: the pattern is applied as a film over the metal; wear rubs it down to the base, starting with raised parts.

Appearance in Field-Tested

The receiver, handguard and the skeleton stock are covered in a hydrographic marble pattern of sandy tan with darker olive-brown blotches and lighter khaki spots. The stock frame carries a paler khaki tone of the same print.

Scuffs become visible along the top of the receiver, the rail area and the charging handle, with light wear on the stock edges. Some of the lighter khaki spots look faded. In game the gun still reads as a uniform tan camouflage, and the wear passes for dirt. The large side panels of the receiver keep most of the pattern.

What to check before buying

• Check where the float sits within the grade, since a low float in Well-Worn or Battle-Scarred keeps noticeably more of the print.
• Look at the top edge of the receiver and the stock frame, where paint loss shows first.
• Pattern placement shifts the blotches slightly, but on this marble finish it does not change the look in a meaningful way.
• A Souvenir version exists, so confirm which version you are buying and whether applied stickers or a name tag suit you.

Who should buy Field-Tested

• Players who want an everyday UMP-45 skin where wear blends into the camouflage.
• Budget-minded buyers who still want the pattern to read clearly.
• The practical grade for this muddy finish.
