COD MW3 Guide: How to Upgrade Guns and Operators to the Highest Level?

When we enter COD MW3 to get a better gaming experience we need to upgrade GUNS and OPERATORS, so how do we quickly upgrade GUNS and OPERATORS in MW3? The following article will give you a detailed introduction to some of the ways to quickly upgrade GUNS and OPERATORS in COD MW3. By following these strategies, you can maximize your XP gain and progress through the game faster.


Method 1: Farm Easy Contracts


One of the easiest methods to farm XP is by completing easy contracts in the game. Contracts like the Delivery Contract and Bounty Contracts can be done repeatedly, providing a steady stream of XP.


  • Deliver Cargo Contract: This contract requires you to drive a car to an extraction point. Complete the contract by driving the car to the marked location and then driving back to the starting point.

  • Bounty Contracts: These contracts involve killing a certain number of enemies, usually with a specific weapon. Toward the end of the game, you can use high-tier Bounty contracts with your Pack-a-Punch weapon to maximize XP gain.


Method 2: Complete High-Risk Contracts


For higher XP gains, you can attempt more challenging contracts like the Tank Contract or the ACV Contract. These contracts will swarm you with zombies, allowing you to get hundreds of kills and level up quickly.


  • Tank Contract: This contract involves killing zombies that have stopped listening to your commands. Wait for the tank to stop listening, then find the source of the zombies and kill them quickly.

  • ACV Contract: This contract has a high drop rate for rare items and is a good way to farm kills and rare items. Drive around in a vehicle and use your Pack-a-Punch weapon to kill zombies.


Method 3: Outlast Contracts


Outlast contracts are a great way to farm XP and kill. You can get an infinite amount of kills in these contracts by leaving the contract area and farming kills around the building while waiting for the contract percentage to drop.


Method 4: Spore Control Contracts

Similar to Outlast contracts, Spore Control contracts involve destroying all spores but one, which will spawn an infinite amount of zombies. This method is considered easier than Outlast contracts because it spawns more zombies and faster, with more special zombies as well.


Method 5: Farm XP Fills


Farming XP Fills can provide a massive amount of XP and level up your guns and operators quickly. Make sure to pack-a-punch your weapons before attempting XP Fills, as they will spawn many special Elite zombies, regular zombies, and armored zombies.


Method 6: Dark Ether and Story Mission


The most challenging and rewarding method is completing the Dark Aether and Story Mission in the game. By breaking the four seals scattered across the map, an infinite amount of zombies will spawn, allowing you to get as many kills as possible. The only downside is that you can only XP Fill by completing the story mission and defeating the worm boss fight or dying.

By utilizing these methods, you can level up your guns and operators quickly and efficiently in Call of Duty Modern Warfare 3. Remember to experiment with different strategies and find the one that works best for you. Happy gaming!
