UMP-45 | Gold Bismuth

Origin Story

The UMP-45 Gold Bismuth features a distinctive gold bismuth pattern layered between white and black base coats. This design was introduced on December 3, 2020, as part of The Operation Broken Fang Collection, coinciding with the launch of Operation Broken Fang. As its flavor text suggests, "You have expensive taste..."

Drop Chance

UMP-45 | Gold Bismuth is Restricted, a Purple-tier skin in the upper half of the rarity ladder. From the Operation Broken Fang 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 Operation Broken Fang Case (about 1 in 313). 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 to 0.7. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($23.80): The gold bismuth finish is pristine and reflects light evenly across the weapon.
• Minimal Wear ($9.15): Minor wear appears on edges, but the overall gold bismuth luster remains largely intact.
• Field-Tested ($4.69): Noticeable scuffs and scratches begin to dull the finish, particularly on prominent areas like the receiver and stock.
• Well-Worn ($5.00): Significant wear and tear are visible, with much of the gold bismuth finish appearing faded and scratched.
• Battle-Scarred ($4.87): The finish is heavily degraded, showing extensive scratching and discoloration, with minimal reflective quality remaining.

Model

Gold Bismuth uses the current UMP-45 model, added with Operation Broken Fang on December 3, 2020. The Gunsmith finish responds to CS2's dynamic lighting.
