The Call of Duty franchise is home to some of the most iconic weapons in gaming, with the series' always-excellent sound and visual design perfectly capturing well-known weapons from across real-world history like the M1 Garand, M16, and M4. But while these historical weapons are always captured well in Call of Duty, they're also available in many other military shooters. Instead, it's Call of Duty's array of original gun designs that have ended up becoming the franchise's most beloved weapons and the vast majority of those come from its Zombies mode.
