In Classified, complete 5 consecutive rounds without leaving the war room elevator in a single game

For all you zombies players out there this is a easy achievement, yet it can be easy to miss. For this achievement you need to start a game on the map Classified I recommend using the difficulty casual to make it easier, however do NOT use mutations if you do it can void the achievement. I would also recommend that you do this with a friend, as there are two different ways the zombies will come from.

Take any class you like & build up points till you can clear each door & block the first elevator. Now take the elevator from the office to the upper war room (remember this costs 500 points). Next clear the junk to get to the lower War room (this costs 1000 points), now you need to clear the junk from in front of the war room elevator this will cost 1000 points). After you have the one & only elevator on the lower level of the War room clear, make sure you are ready to hold off 5 rounds. I like to buy the ICR-7 off the wall in the lower war room, it will give you the damage & ammo you need to complete 5 rounds.

Make your shots count & remember the window at the back of the elevator, zombies will spawn there. Make sure that you or any of your team mates do not leave the elevator till the 5 rounds have passed, or the achievement will not unlock. This video I made will show you exactly how to do each step, if you have any questions just ask!

There are two possible locations for the mystery box to spawn at the start of your game.

1) - Main Offices
2) - War Room Upper Level

Ideally you will want the mystery box to spawn in the War Room Upper Level because it will save you having to buy the door to the Main Offices.

For this you will want to get really good weapons from the mystery box such as the Winter's Howel, Hades, Ray Gun, Titan. You will then need to buy the War Room elevator and stay in here for 5 rounds in a row.

Good Elixirs to have are as follows...

Burned Out - When zombies get near you and hit you a large ring of fire will fly around you and kill the nearby zombies.
Equip Mint - Allows you to essentially get a max ammo for your equipment. Overpowered partially with Monkey Bombs.
Arsenal Accelerator - Allows you to charge your specialist ability faster.
Pop Shocks - Good if your in a tight situation, when you melee all nearby zombies will be electrocuted.

For specialist ability I recommend having the Overkill (Death Machine) as it's pretty useful when camping inside the elevator. There's one window inside the elevator, so you will want to have your back facing the window and concentrate on the entrance of the elevator. Every so often turn around and shoot the zombies breaking down the window.

For a dog round let them all come into the elevator to grab the max ammo.

Call of Duty: Black Ops 4 Pent-up-agon/Crawl for Help Achievement Guide

Hope this helped.

Round 1 – 1 shot and knife zombies, open door to elevator hallway for 500.

Round 2 – 2 shot and knife zombies, open elevator for 750.

Round 3 – take elevator down for 500, at this point you will need to clear the debris for 750 and clear the elevator debris for 750 as well as have weapons you feel good with. I would suggest using round 3 to buy the MX9.

Round 4 – shoot a couple bullets into the zombies then knife them, leave one alive. Rack up points to grab the spitfire as your second weapon and then once you can clear both sets of debris go to the elevator and finish the round. This is important because ending the round in the elevator will count as 1 round of your 5.

Round 5-8 – stand in the elevator and don’t leave. Switch between weapons and try to land head shots to conserve ammo. If you need to you can use your special weapon. Make sure on the dog round you let the last dog come in the elevator so you can reach the max ammo, you cannot leave the elevator to go out and get it.
