When the Nuketown 84' map dropped in Cold War Zombies had a weapon experience glitch where you can max your weapon in very few rounds. But the next day it got patched and players are still peeved about it. However there are a few ways you can maximize your experience gain.
Strategy 1:
Platstation Players Only | Invite Friends and Restart Every 5 Rounds
One way to supersize your weapon's experience bar is by setting up a lobby with 1 or more people and on the bottom of your player list there should be text saying party boost active. This gives an exclusive 60 percent bonus to Playstation players. Once you load in the game, have them afk and have one person get all the kills then restart at the end of round 5 until level 50 then restart at the end of level 3. You can have it set up to where each of your party members gets a turn to max level their gun and switch it out every time or switch when max.
Strategy 2:
Playstation Players Only | Party Member Bonus and Tag Zombies to Share Weapon XP
This way is a little more difficult but allows everyone to get the experience at the same time. How it works is you have one person killing but you have each of the other players 'tag' the zombies and have one person kill so that the xp is shared. From what I can tell the grind for the weapon experience is the same regardless if you kill them solo or share the kill. Depending on your gun I suggest the sharing technique. For example, SMGs, assault rifles, and some pistols and tactical rifles can do small damage per shot. Unlike shotguns, snipers, and launchers in which case I advise using the afk friend/s strategy.
Strategy 3:
PC/PS/XBOX Players | Playing Online Matchmaking
Playing in multiplayer matchmaking lobbies gives players more weapon experience because of playing with other people. From what I can find there is no other way for PC/XBOX players to farm at the rate of experience we got before. if there is I will bring updates and news for the experience on the site.
Strategy 4:
PC/PS/XBOX Players | Solo - Camp Wonderfizz Until Round 10 and Repeat
This is the only way to farm weapon experience solo. Buy all the doors up to the Wonderfizz Machine and camp there. There is only two spots where sombies spawn so it should be easy and that area can be trained if you have issues. It doesn't give as much xp as in multiplayer but at least you can confirm all the kills.
The Current State of Weapon XP for Existing Players.
Many players are feeling distraught because of the lack of weapon leveling. Players are feeling shafted in experience gain when they go higher rounds in solo. Some reports on the CODZombies reddit say that players get hundreds to thousands of kills and barely any levels to show for it. If you aren't a zombies player though then I hear multiplayer's experience is just fine so go there if you want for the time being. Hopefully next patch they decide to increase xp gained.
