The M4/M4A1 5.56mm Carbine is a lightweight, gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. It is now the standard issue firearm for most units in the U.S. military.
Call of Duty: Mobile offers a wide variety of weapons, but only a few are as iconic as the M4 assault rifle, also popular as the M4A1 among Call of Duty fans, after appearing in multiple main series titles, including MW & MW2.
Coming out of Black Ops 2, Mob of the Dead is the best CoD Zombies map and the closest to perfection that the entire Call of Duty franchise has been. Alcatraz Prison is turned into a hellscape for this map and serves as the perfect horror-filled setting for a zombie invasion.
Black Ops 3 is a lot of fun and features some great gameplay, and some of the best maps in Zombies history. Black Ops 3 has a bundle of DLCs that add new Zombies maps. Some old, some new.
