Call of Duty: WWII

This one is really simple with the following strategy.

1. Pre-match: Customize one of your load outs to have the "Camouflage" Special ability (the default class w/ Camouflage will probably work too, but the custom class gives you the best odds). Equip the "Resourceful" mod & ideally the "Specialist Training" mod (you will have to level up a few times in order to unlock the 2nd one).

2. Join a Public match, the more people (usually) the better. Make sure to select you custom "Camouflage" class from step 1! The camo ability is key to making it super easy.

3. The 1st pest round comes approx. around rd 7-9. Up until this point you will want to have your special meter full & your Camouflage ability ready to use. You will hear an audio cue both as a quote from your character mentioning something about flies not belonging here or a bad feeling or something similar, as well as (this is more noticeable) a loud buzzing of flies marking start of a pest round.

As soon as they start spawning in you want to activate the camouflage ability, while also finding a good spot to camp in case the round is still going on after your ability runs out. The 1st pest round is quick so you won't have to really worry (and can be done by simply camping, especially w/ teammates), but just always be aware of your surroundings, use the audio to alert you of danger (the game even has an audio alert system to tell you there's a zombie out of your view closing in), & again try to end the rd before your camo runs out but if it does just make sure you are in a spot they won't spawn on out of your view or behind you.

4. Repeat for the next 2 pest rounds. Always save you camouflage in between pest rds unless you absolutely have to use it. They vary in frequency but approx every 4-7 rds is a pest rd (not 100% sure) so you want to make you the ability is primed.


Tips:
-Though I can't give specific locations, if you experiment w/ leaving a gate closed, you can probably use them as good camping spots where you know the spawns are only in front of you
- The Heart Power Up is a huge help. It not only fully fills your ability meter, but it overcharges it as well, effectively doubling the time of the Camouflage ability. (This is why you want the "Resourceful" mod on to increase your chances of getting them.)
- The Specialist Training mod is also extremely helpful as it decreases the required energy to use Camo, making it more assured you'll have it ready for the next pest rd.

This is probably easiest if you have a team of 2-4 with the person wanting the achievement having camouflage and everyone else having frontline. Each pest wave (every fifth round. 5, 10, 15, etc.) activate your camouflage, and if the round isn't over then have everyone activate their frontline 1 at a time.

Note: I very easily got this solo by using camo exclusively on pest rounds and just training around the hole next to the command door with an M1 Garand.

heya guys ... so this achievement can be pretty tricky but i made a video guide below that is pretty easy to follow ... all you got to do is run camouflage , then when the pest rounds start just pick them off from a distance and if they get too close or too many of them use your camouflage

Not a solution as such but just wanted to quickly state that this has to be done in 3 consecutive rounds not 3 rounds altogether but it can still be earned if you fail a round.

For instance i completed round 5+10 but failed 15 then continued on and completed 20-25+30 and the achievement unlocked.
