There’s a new ultra-fast method to level up your guns and unlock camos in MW2 – here’s everything you need to know!

Modern Warfare 2 requires players to grind hard if they want to unlock all of its content. After all, thanks to the new Receiver system, just getting one weapon to max level is no longer enough to acquire all of its attachments.

On top of that, players will also have to use specific weapons to unlock others in its family, meaning that you may need to utilize a few guns you don’t like in order to get to the ones you want.

Thankfully, there’s a new way to level up guns (and grind for those mastery camos) fast – so take advantage before Infinity Ward patches it:

How to Level Up Guns Fast in Modern Warfare 2

To level up guns fast in MW2, enter an Invasion game and focus on killing AI with your chosen weapon, as they award more weapon XP than regular players.

Stick to the edges of the map where AI spawn for some easy XP and camo grinding. When AI start putting armor on, leave the match and re-queue once more.

  • First, use a Double Weapon XP token if possible.
  • Create a class with the weapon you want to level up, as well as a Tactical Insertion and Munitions Box (if possible) to make this method easier.
  • Load into the Invasion playlist.
  • Drop into the outskirts of the map to avoid real enemies and find areas where AI are spawning in.
Fastest Way to Level Up Guns in MW2
  • Take out as many AI as possible with your weapon of choice while they’re still weak at the start of the game.
  • When AI players start putting on armor, back out of the match and queue up again.
  • Not only will repeating this process net you a huge amount of weapon XP, it’s also a great way to unlock all MW2 weapon camos!

Using this method, Call of Duty expert JGOD was able to level up each gun to max in less than an hour, making the grind easy. It’s not currently clear whether or not AI giving more weapon XP than regular enemies is a bug or not.

UPDATE: A new Modern Warfare 2 Weapon XP glitch is letting players level up guns even faster than this!

This method is tested and working as of October 29, 2022
