Description

The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. This custom paint job is inspired by old animation cartoons. <i>Swing and a miss!</i>

History

Released with the Fever Case, one of CS2's most recently launched active cases.

Origin

Inspired by old animation cartoons — swing and a miss! A retro cartoon aesthetic on a weapon that absolutely does not miss.

Popularity

Active Fever Case keeps K.O. Factory in steady supply; the old-cartoon animation style is a fresh and distinctly playful direction for a Classified UMP-45 design.

Rarity

Classified — approximately 1-in-156 from the Fever Case. StatTrak versions are available.

Availability

Sourced from the Fever Case, actively in rotation. Full float range (0–1).

Versions

Full float range (0–1). StatTrak variants available across all wear conditions.

Finish Style

Custom paint — vintage animation cartoon-inspired design.

Community Sentiment

Well-received for its playful retro animation aesthetic on a Classified from one of CS2's newest cases; K.O. Factory occupies a unique personality niche in the UMP-45 Classified tier.
