World War Z

This achievement requires you to complete 100 chapters in either Offline/ Online Co-op Campaign, or a combination of the two.

I would suggest going for this achievement AFTER you have unlocked all of the other achievements minus "Handyman".

*Note you do not need to complete a full episode to get credit towards this achievement; however, you MUST be present at the end of the chapter in order to credit. This means if you join a game in progress and complete it, you will still get progress.

With the above not, I used this to my advantage. After obtaining all of the other achievements, I still needed 35-40 games in order to wrap up this achievement. If you'd prefer to grind this by yourself I will provide a guide for that as well.

SOLO TIP:
New York: Hell or High Water.

I found this mission to be the fastest as you can run past the first few sections without much hassle. Since you will most likely still need credits, I would suggest doing this on Hard as it really is not that hard at all. I personally preferred to play as either the Medic or Fixer class as they have great perks to help evade zombies.

ONLINE CO-OP TIP:

I decided I didn't want to grind this solo as it gets rather boring, so I decided to see if I could speed this up.. What I did was used the Co-op Online Quick play feature to find games in progress as well as searching for New York: Hell or High Water on Hard for games in progress. I was able to consistently find games that were at the first defense section or farther which greatly reduced the amount of time I needed to play the each mission.. Out of the 40 chapters I needed, about 8 of them I joined were at the final defense section. At the time of writing this the online co-op is still very active meaning there are a lot of games running (May 2019).

You will be able to tell if a game is in progress as when you join a game lobby in the Online Co-op feature, as it will say on the bottom right of the screen that the game is in progress, and once you ready up, it'll put you in the game.

If you have any other tips and tricks you think I could add, feel free to drop them in the comment section below.

this is a method for boosting handyman, money for madman and ranking up offline characters
I describe a method for 4 people, but it works similiar for 3 people too.
I think its more effective as the moscow suicide method.

Dont forget to turn on 5 specific mutators as known as
(thx to Kelle 1994 )

1.Cannon Fodder
2.Light Waves
3.Heavy Hitters
4.Looter
5.Die Hard


and running the first New York level as a fixer on extreme difficulty.
(Sometimes a bull appears in the elevator.
You can:
1. ignore this guy, when he is charging and catches a bot. Step to elevator, bots will spawn in the next sequence.
2. throw a grenade and stab him in his back.

1. Player A + Player B are running together as a Duo(
carrying 8 chest in the end phase)

While Player C + Player D are running Solo.
( Its important to trigger the motorman phase, and carrying chests near to the end, otherwise you have to carry 12 or more chests - Solo runners shall take their time with hordes

After A + B finished their run, they jumping in the game of C (choose characters to rank up)
and finish C's game.(hey have to carry 7 chest)
After this run, A+B+C jump in the game of D and finish this run.

And after this run; switch positions:
2. B+C running as a Duo , while A+D running Solo (D = second finish ; A= third finish)
3.C+D running as a Duo , while A+B running Solo (A= second finish + B = third finish)
4 D+A running as a Duo , while B+C running Solo (B= second finish + C third finish)


When your quick and know what to do, a run takes (depending on loading times)
20-25 minutes
My Squad finished this turn (these 4 runs) almost in 1 1/2 hours and
everybody earned 9000 Credits , some bluecredits for skins and a progress for 9 games for madman achievements.
