That in itself is important, but there is another lesson, getting the gun right. The Peacekeeper is one of the most widely used fictional MSF weapons at the moment, with millions of Black Ops: II players (with the HALO weapons at a close second) using the Peacekeeper. Science fiction creators often develop their own unique weapons, and this video game fictional weapon is a good lesson to all of us that are MSF creators. The Peacekeeper: Broken Down Piece-by-Piece Weapons like the cancelled Knights Armament PDW, which was styled after the Colt M4, but chambered the custom designed 6.x35mm cartridge, or the also cancelled Colt MARS that chambered the 5.56x30mm round, or even the Magpul PDR are similar to the Peacekeeper of 2025. To me, the Peacekeeper is stylistic extension of a type of weapon that is taking shape in law enforcement, counter-terrorism, and VIP protection circles the hybrid compact gun that sits between the carbine and PDW. If the Peacekeeper had chambered a normal assault rifle cartridge, than it could have fallen under the commando carbine list. 45, but, firing the 5.7x28mm round and not a common pistol cartridge firmly places the Peacekeeper in the personal defense weapon category. The original drawings for the gun were similar to the H&K UMP. While they did get it right with the interesting PDW-57, but they failed when it came to labeling Peacekeeper an 'SMG'.

Per normal, Treyarch didn't do their research on the actually firearms definition of what an SMG or PDW is.
