- "A powerful, high-caliber tactical SMG. This weapon has an excellent combination of attributes and a wide range of customization options to fit any tactical environment."
Based upon the real-world Heckler & Koch UMP (Universal Machine Pistol) SMG, which was created as the designated successor for the popular MP5 SMG, being chambered for a variety of larger caliber rounds with more stopping power than the standard 9mm hot pistol round fired in other SMG's (including the MP5). Unique to this version, the Agency HX UMP has an ICA mark on the weapon.
