About the UMP-45 | Gold Bismuth
The UMP-45 | Gold Bismuth was added in December 2020, in The Operation Broken Fang Collection. In CS2 it still uses the legacy weapon model.
“The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. A gold bismuth pattern has been sandwiched between white and black base coats.”
“\"You have expensive taste…\"”
