UMP-45 | Warm Blooded

Origin Story

The UMP-45 | Warm Blooded, released on January 22, 2026, is part of The Harlequin Collection. Its design features a tan and red animal print pattern, described in-game as "a tan and red animal print pattern has been applied." The flavor text, "You said "a few animals", not "the entire animal kingdom"," hints at the dense, full-coverage nature of its animal-themed hydrographic finish. This skin presents a distinct visual for the UMP-45, focusing on a wild, untamed aesthetic.

Drop Chance

UMP-45 | Warm Blooded is Mil-Spec, a Blue-tier skin, less common than base collection drops. It can drop as an end-of-match reward from active competitive play on the Harlequin Collection item pool. Map drops follow a weighted rarity system that heavily favors common grades, so Mil-Spec drops are uncommon and Valve doesn't publish per-skin odds. There are 3 other Mil-Spec skins in the collection competing for the same drop slot. Most copies enter the market through trade-up contracts or direct purchase at a listed seller's price.

Skin Condition

Float range 0 to 0.7. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is not available for this skin.

• Factory New ($1.61): The tan and red animal print pattern is fully intact and crisp across the receiver and body of the UMP-45.
• Minimal Wear ($0.72): The pattern remains nearly full, with only tiny edge specks or micro-scratches appearing on exposed parts like the front edges.
• Field-Tested ($0.34): Noticeable chipping and scratching appear on edges and corners, with small areas of the tan and red animal print starting to break up.
• Well-Worn ($0.41): Significant pattern loss is visible on exposed areas, and the animal-print motif looks partially eroded with larger regions of base material showing through.
• Battle-Scarred ($0.25): Heavy wear covers much of the surface, with large sections of the tan and red print missing or extremely faded, making the remaining pattern appear patchy and muted.
