UMP-45 | Mudder (Battle-Scarred)

Skin overview

This is the most weathered version of UMP-45 | Mudder, a tan marble camouflage that turns patchy and dusty here. Battle-Scarred copies show bare metal over many edges and raised areas, while the brown blotches survive in the recesses. For a finish themed around mud, the heavy wear reads as fitting rather than broken.

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 Battle-Scarred

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.

Large areas of bare metal cover the top of the receiver, the handguard edges, the charging handle and much of the stock frame. The brown blotches remain mostly in recesses and the middle of the side panels. In game the gun looks greyish-tan and weathered rather than clearly patterned. Since the float range stops short of the maximum, the heaviest copies still keep some of the print.

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 Battle-Scarred

• Players who prefer a heavily weathered, dusty appearance.
• The cheapest way to add a finish to the UMP-45.
• For those who see heavy wear as fitting the mud theme.
