|quotetext=Although the [[MP5]] family of submachine guns remains an enduringly popular staple in the Mazes, there was still a market for shooters of various backgrounds looking for a submachine gun designed to fire larger calibers; the 9x19mm caliber is extremely dominant in the SMG world, and even though the MP5 has variants in .40 S&W and 10mm Auto, they are not as popular as the original 9x19mm version. The UMP series was introduced to attempt addressing these needs. The UMP is a lightweight, simple submachine gun, using a lightweight polymer receiver, a folding stock, and a simple, straight blowback system instead of the MP5's more complex roller-delayed blowback action. All versions have a low, controllable rate of fire, making them pleasant to shoot even in full-auto. This version of the UMP is the UMP-9'''UMP9'', chambered for 9x19mm, and was the third and last one introduced.
