Call of Duty: Modern Warfare 4 - Gunny Loadout System Explained - IGN

If you’ve ever felt like Call of Duty’s weapon customization requires a degree in spreadsheet management just to build a decent loadout, Modern Warfare 4 has a new solution for you. Enter Gunny, a brand-new tool designed to remove the friction of the traditional Gunsmith. Whether you’re a newcomer or a seasoned veteran, Gunny allows you to simply pick a gun and a preferred playstyle—like long-range, balanced, or close-quarters—and instantly equips a tailored, usable weapon setup based on the attachments you've unlocked.In this video, we break down exactly how the Gunny system works in Call of Duty: Modern Warfare 4. We explore how you can reroll playstyles to get completely different attachment combinations, swap out individual parts like a drum mag while keeping the overall build intact, and why it won't replace traditional full Gunsmith customization for those who still want total manual control. Gunny proves to be a surprisingly effective addition to the loadout process that gets you into multiplayer matches faster without hamstringing your options.
