The UMP-45 | Riot is a Mil-Spec-tier SMG finish in Counter-Strike 2, originally introduced as part of The Falchion Collection when the Falchion Case launched in April 2015.

The float range for this finish is restricted to 0.00–0.70, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for UMP-45 | Riot are tracked across 17 marketplaces, with prices spanning $0.33 to $42.96 depending on wear, variant, and seller.
