Origin Story
The UMP-45 Bone Pile features a macabre design, painting skulls over a wiring diagram. This memento from the Cache map was released on September 19, 2013, as part of Operation Bravo. As a Mil-Spec item from the highly sought-after Bravo Collection, it is primarily relevant to collectors focused on completing older, prestigious sets.
Drop Chance
UMP-45 | Bone Pile is Mil-Spec, a Blue-tier skin, less common than base collection drops. From the Operation Bravo Case: approximately 13.32% per opening (roughly 1 in 8). The 79.92% Mil-Spec tier rate is split across 6 Mil-Spec skins in the case. StatTrak versions drop at ~1.33% from the Operation Bravo Case (about 1 in 75). These per-skin odds assume equal weighting within tier — Valve publishes tier rates but doesn't formally confirm even distribution across skins in a tier.
Skin Condition
Float range 0.06 to 0.34. Exteriors: Minimal Wear, Field-Tested, Well-Worn. StatTrak is available in MW, FT, WW. Minimal Wear ($7.24): Minor edge wear begins to appear on the stock, barrel shroud, and upper receiver, but the central skull pattern remains clear and vibrant. Field-Tested ($6.87): More noticeable chipping and surface wear develop on the weapon's ends, and the skull pattern shows some fading and roughness while still being clearly recognizable. Well-Worn (No Recent Price): Significant chipping along edges and wear patches on the mid-body are present, with some parts of the skull motif potentially eroded. Colors appear duller, with more visible base surface.
Model
Bone Pile uses the legacy UMP-45 model, introduced with Operation Bravo on September 19, 2013. The inspect animation and third-person appearance match the original CS:GO version.

Sticker Compatibility
The UMP-45 | Bone Pile's subdued palette of dark gray, black, and muted tan-beige makes it suitable for stickers in white, bone, or light neutral tones that complement the skull motif. Dark gray or black stickers can also blend into the base, enhancing the visibility of the skin's design. The most visible sticker slots in first-person are typically on the receiver, particularly those near the rear and above the magazine.
