UMP-45 | Fallout Warning

Origin Story

The UMP-45 | Fallout Warning features bold radiological warning hazard patterns, directly reflecting its in-game description as being spray-painted with these designs. Released on August 14, 2013, as part of The Arms Deal update, this skin belongs to The Nuke Collection. It is recognized as a thematic, radioactive-hazard style budget pick, particularly appealing to enthusiasts of the Nuke map and its associated collection. The skin's visual identity, dominated by muted yellow/orange hazard tones and a dark gray/black base, aligns it with other nuclear-themed skins from its collection.

Drop Chance

UMP-45 | Fallout Warning is Industrial Grade, a common skin tier, one step above Consumer Grade. It has appeared across 8 tournament packages, most recently the ESL One Katowice 2015 Nuke Souvenir Package, Krakow 2017 Nuke Souvenir Package, and MLG Columbus 2016 Nuke Souvenir Package.


Souvenir Packages are awarded to viewers watching live Major matches on the corresponding map, not opened from cases, so Valve doesn't publish per-skin drop odds. Each package contains one item from The Nuke Collection, with rarity tiers drawn on a weighted system that heavily favors common grades, meaning Industrial Grade skins like Fallout Warning are a small fraction of total package contents. There are 2 other Industrial Grade skins in the collection competing for the same drop slot. New copies only enter the market when a recipient chooses to open their package, so supply trickles in over time even after the tournament ends.
