The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. It has been spray-painted with radiological warning hazard patterns.
This skin was introduced in 2022 as part of the Fracture Collection, available through the Fracture case released alongside the CS2 launch. It is a community-designed skin that quickly gained popularity.
Fallout Warning displays a hazard-themed pattern with yellow and black caution stripes, along with radioactive green accents on a matte black base, evoking a post-apocalyptic vibe.
Known for its bold design, Fallout Warning is highly sought after, especially by players who favor warning and hazard motifs, resulting in steady market demand.
