So this achievement is going to take quite a bit of time and a bit of a grind, especially due to the new patch that came out which states that you can only level up a weapon once you've unlocked the previous level. So, for example, you can only start levelling up to a level 4 gun once you've unlocked the level 3.

You level up guns by getting zombie kills and special kills. A zombie kill is 1XP, a special kill is 3XP.

Once you reach the XP cap on the level, you unlock the next gun through the game currency that you earn by completing episodes or online PvP games. It's going to cost you a total of 51,200 credits if you're starting from a brand new fresh account to upgrade all weapons to the max level, so yes it's a big grind to get the credits alone.
For the guns that have TWO rows you only have to unlock ONE row of the two
Here is the best class XP and Credits farming method at this moment in time, I'll update it if someone finds a better one

Now here's the list of weapons that you will have to do -
* = Two level 5 weapons that have to be upgraded on that gun

Tier 1
Scout Rifle*
Compact SMG
Machine Pistol

Tier 2
Assault Rifle*
Sporting Carbine*
Combat Shotgun
Sniper Rifle*
Compact Shotgun

Tier 3
Assault Carbine*
Battle Rifle*
Bullpup Rifle*
Advanced SMG*
Assault Shotgun


In the Gunslinger class you can unlock perks which allows you to start with the Sporting Carbine, Assault Rifle, PDW, and Compact Shotgun.

My main method of grinding out different guns was repeatedly playing Episode 1: New York Chapter Descent mainly because there are a lot of weapon crates near the opening areas of the levels, and before your first defence point, but you can choose whatever Episode suits you, that was just a personal choice of mine.

Holding the cn_back button brings up the leaderboard, and also brings up your level progression in the bottom right. Once you've reached the cap, you can swap out for another gun through whatever Episode you're playing.

If you want to know anything else about it, please don't hesitate to ask in the comments. Happy grinding laugh
