COD Easy Fix & Loadout Guide: How to Equip MW3 Weapons in Warzone

With the late 2024 integration, Call of Duty: Warzone now boasts nearly 200 weapons from Modern Warfare 2, Modern Warfare 3, and Black Ops 6. This massive arsenal lets players customize loadouts for any combat scenario, offering tons of strategic flexibility and opportunities to fine-tune playstyles.

However, with so many guns available, some players struggle to locate and equip MW3 weapons in Warzone. Don’t worry—we’ve got you covered. Here’s a quick and easy guide to help you unlock the power of MW3 guns in your loadouts.

How to Equip MW3 Weapons in Warzone

The Key: Avoid the Gunfighter Wildcard

The main reason players can’t equip MW3 weapons in Warzone? The Gunfighter Wildcard—this restricts MW3 guns as it’s exclusive to the Black Ops 6 arsenal. To unlock MW3 weapons, remove Gunfighter and pick another Wildcard, like Overkill.

Why Overkill?

• It allows you to carry two primary weapons in one loadout.
• It unlocks access to MW3 guns alongside other weapons.

 

 

Step-by-Step Guide:

1. Open the Call of Duty app.
2. Select Warzone from the main menu.
3. Head to the Weapons section.
4. Choose the loadout where you want to add MW3 weapons.
5. Equip the Overkill Wildcard (or any Wildcard except Gunfighter).
6. In the Primary/Secondary Weapon section, scroll right using your controller or click the MW2/MW3 logos depending on the weapon you’re after.
7. Select your MW3 weapon from the list, and you’re good to go!

Why Can’t I Use MW3 Weapons in Warzone?

If you’re still having trouble, it’s likely due to the Gunfighter Wildcard. This Wildcard gives eight attachments but only for Black Ops 6 weapons. Since MW3 guns don’t qualify, they get locked out when Gunfighter is equipped.

Quick Fix:

• Remove Gunfighter.
• Choose Overkill or any other compatible Wildcard.
• Enjoy your MW3 arsenal in Warzone.

Why MW3 Weapons Are Still Worth Using in Warzone

Even with Black Ops 6 weapons being the latest trend, MW3 guns remain fan favorites—and for good reasons:

1. Maxed Out Attachments

• Long-time players likely have MW3 guns max-leveled, unlocking all attachments.
• No need to grind new weapons—just equip and dominate.

2. Familiarity & Mastery

• Consistency matters. Many players are simply more comfortable with the weapons they’ve used for months.
• Mastered guns = better performance.

3. Still Part of the Meta

• Balance updates can bring older weapons back into the spotlight.
• Some MW3 guns continue to dominate the meta thanks to solid stats and reliable handling.

4. Flexibility Across Titles

• Warzone’s integration lets you mix and match weapons from different games.
• Create hybrid loadouts tailored to your playstyle for a competitive edge.

Final Thoughts: Load Up and Lock In

With nearly 200 weapons available in Warzone, it’s easy to feel overwhelmed. But with this simple guide, you’ll be rocking your MW3 favorites in no time.

Just remember:

• Ditch Gunfighter.
• Pick Overkill.
• Scroll, select, and slay.
