From GameWatcher: “Apex Legends seems to have its own version of the legendary Model 1887 lever-action sniper-shotgun that fans of the original version of Call of Duty: Modern Warfare 2 will recall with glee and/or horror, depending on which end of it they used to be at. It’s called the Apex Legends Peacekeeper.”
