UMP-45 | Exposure

Origin Story

The UMP-45 | Exposure features a custom paint job that transforms the weapon into an x-ray, complete with a detailed rib cage and skeletal motif. Released on September 14, 2017, as part of The Spectrum 2 Collection, this skin offers a distinctive visual theme. Its high-contrast white and blue skeletal graphics over a dark background create a "medical scan" appearance, making the ribcage along the UMP's body a prominent feature in first-person view. This design stands out for its unique interpretation of an x-ray, providing a memorable aesthetic for the UMP-45.

Drop Chance

UMP-45 | Exposure is Restricted, a Purple-tier skin in the upper half of the rarity ladder. From the Spectrum 2 Case: approximately 3.20% per opening (roughly 1 in 31). The 15.98% Restricted tier rate is split across 5 Restricted skins in the case. StatTrak versions drop at ~0.32% from the Spectrum 2 Case (about 1 in 313).

Skin Condition

Float range 0 to 0.55. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($4.20): The ribcage, spine, and x-ray details are crisp and fully intact, with bright whites and blues against a deep dark base, showing minimal to no visible edge wear.
• Minimal Wear ($1.38): Very light, localized wear begins to appear on sharp edges, but the central ribcage graphic remains very clean and bright, preserving most of the FN look.
• Field-Tested ($1.27): Visible wear on edges and high-contact zones becomes more pronounced, with parts of the skeleton lines near edges looking slightly worn, though the ribcage is still clearly recognizable.
• Well-Worn ($1.28): Heavy edge wear and broader surface scuffing are present, with sections of the dark base and skeleton art showing clear abrasions or lighter patches, making the skeletal pattern look broken in areas.
• Battle-Scarred ($1.23): Extensive fading and chipping are evident across the skin, with the core ribcage motif remaining visible but clearly aged and degraded against a heavily worn background.

Visual Theme

Custom Paint Job: A custom paint job has been applied which resembles an x-ray; rib cage and all. This design features a bright white and blue x-ray skeleton over a darker, mostly black and grey weapon base, creating a high-contrast medical scan aesthetic. The ribcage and spine graphic, running along the main body of the UMP, is the most visible element in first-person view. The community implicitly compares its thematic elements to medical x-ray imagery and body scans.

Sticker Compatibility

The UMP-45 | Exposure's white and blue x-ray design on a dark background pairs well with blue, teal, white, silver, and other cold-toned stickers, particularly those with futuristic or skeletal themes. Bright neon colors can also create a strong contrast against the dark base. The rear receiver and magazine slots are the most visible in first-person view, making them prime locations for sticker application.
