Earning XP in Modern Warfare 3 is crucial to level and weapon progression. Players who know how to farm XP in the multiplayer and Zombies mode can quickly unlock powerful armory and systems, level up, and gain access to various attachments. However, earning XP can be a slow and tedious process in MW3, especially for complex challenges and objectives.
Players who want to level up fast should employ the right strategies to farm XP. This way, they can unlock weapons faster and get some of the best gear, accessories, Operator skins, and field upgrades before others do and overpower them. Here’s a guide on the fastest ways to earn XP in MW3.
The Fastest Ways to Earn XP
To earn XP fast in MW3, players can:
Complete Weekly Challenges
To earn XP in Modern Warfare 3, players can complete daily and weekly challenges, defeat enemies and zombies in the various game modes, or complete contracts. While these objectives reward players with XP, some offer more than others, making it crucial to pick the right challenges to earn XP fast. For example, the weekly challenges are worth 10,000 XP, while the daily challenges offer 2,500 XP. So, if a player wants to earn XP fast, completing the weekly challenges is better suited to farming the most.
Kill Zombies
Another fast way to earn XP in MW3 is to kill the undead in the Zombies mode. The undead normally swarm the map during the last 15 minutes to attack players and prevent them from reaching exfil locations to move out successfully. Destroying the large horde of Zombies is an easy way to rank up XP fast and level up.
However, players must ensure they have the best weapons for long-range combat, such as sniper rifles, to take down the swarm of zombies from a distance. Getting too close can be risky as they can overpower and kill players. This strategy requires players to be fast, calculated, and good at downing Zombies within a short time frame.
Complete Weapon Challenges
Weapon challenges are among the fastest ways to earn XP in Call of Duty. Some weapon challenges can reward players as high as 10,000 XP, but they take longer to complete.
Choose The Right Mode
Modern Warfare 3 has various game modes players can choose from, but some offer more XP than others. For example, in Search and Destroy and Grounded, players can secure the most XP as kills offer double XPs.
