Call of Duty: Vanguard has a wide variety of weapons with many attachments to go with them. One of the most interesting things is the addition of two more attachment slots instead of the standard eight that we've seen in Modern Warfare (2019) and Black Ops Cold War.
Having more attachments and attachment slots allows you to build your weapon in many ways, hence making attachments in Vanguard one of its primary focuses. This is why everyone is constantly leveling up their favorite weapons, so they can use the gun to its full potential.
Each weapon can be ranked up to level 70 and has over 200 unique attachments to choose from. Now, as you can imagine, leveling up your weapon takes a long time in Vanguard. And, it can be extremely tedious if you're playing multiplayer as the XP rates are not predictable, given you can sometimes have an excellent game and a terrible game. Each weapon requires 150,000 XP to max it out fully.
However, there is a way to cut that time into almost half if you play the Zombies mode. That's right. Indeed, Vanguard Zombies didn't have much to offer in terms of content, but it is an excellent way to level up your weapons. But, that should also be done in an optimized way to ensure you are getting the maximum possible XP in the shortest time possible.
The way you can level up your weapon in Zombies is straightforward and requires you to get just 35 kills, exit the game, and restart. While it may sound super simple, it is also a very monotonous process but much faster than sitting through the regular multiplayer games. But, the kills you get should not be with the gun by shooting the zombies. Instead, you must get all the kills by meleeing the zombies. Meleeing the zombies gives more weapon XP.
