How to unlock the The Doctor is In achievement in Call of Duty: Black Ops 4 - Definitive Guide

Map: Blood of the Dead
Difficulty: Casual

Before launching, your 4th perk slot must be filled with Secret Sauce (random perk given upon each purchase), or PhD Slider (unlocked at Level 42). This MUST be in the modifier slot, or the achievement will not unlock. All four perks must also be purchased to activate the modifier shown as a gold border on the 4th perk.

Now, you'll need to train a bunch of zombies in the Power House. You'll notice a large staircase leading from West Grounds to this area, and this is what we'll jump off for the achievement. If done correctly (see video), this can be done solo with a normal zombie train. However, you may find that it is easier with:
- A co-op partner helping you train
- Monkey bombs attained from a mystery box or unlocked through the stone monkey statute

With a large group of zombies, get a sprinting start, jump in the air, hold crouch while the the air, hit the zombie group killing at least 10, and the achievement unlocks. Keep in mind the perk must be recharged with slides if you set it off but fail.

Just an FYI cause I'm an idiot but PhD slider only works when you slide into zombies. I spent a couple rounds thinking it would activate just by jumping and sliding.

Can't believe I had so much trouble with this one originally... I was lazy and used a Perk-a-holic to save time buying all 4 perks + get the modifier for Flopper being my 4th perk. The longest part was rolling the box for monkey bombs, even with me spawning a load of fire-sales. I got it on my first monkey, at round 11 (I was playing it safe numbers wise).

Undead man walking works like a charm. Activate it when you have your train and you're golden. There's probably going to be a couple dogs in the beginning of the round so take those out first. They can mess it up. I got this in round 12 on blood of the dead. Same spot as in the video.

Just wanna add that this is also doable on IX. I used undead man walking and got a train of about 20 in pack a punch room. I ran up the stairs then waited till the were at the bottom and the ran jumped and slid and killed over 10. Achievement popped.

This one was coded terribly.

To unlock PHD u need to be level 42. It works if you put ‘secret sauce’ in the modifier slot as well. You need to equip PHD/secret sauce in the modifier slot, and purchase all four perks to activate the modifier or it won’t work.

Boot up blood of the dead and go above the workbench at docks. You need to use a monkey bomb if in solo, or (more preferably) have a friend train by the workbench. If it doesn’t pop for you, make sure to have some horizontal distance on the jump. I had stamin up on

TLDR: Put PHD in modifier slot and jump off docks to get 10 kills. Must have all perks bought.

If you have the percaholic elixir just equip it go to most any stairs and you can get achievement. Very quick and easy.

A second player isn't technically required for this but is highly recommended! PhD Slider is the final perk unlocked, obtained at level 42. Among other benefits, it allows you to charge up the ability to slide into a zombie to cause an explosion. When equipped in the modifier slot (Odin/Tonic) after obtaining all four perks, the explosion will be larger when sliding from a larger height, meaning you should equip PhD in the final slot. The map doesn’t matter but Voyage or Blood would be easiest, I obtained this on Blood.

After I obtained all four perks, I had a second player train zombies near the Power House. I slid around to fully charge the ability (the perk icon will flash), then when I was ready, the second player led the zombies near the bottom of the large staircase, far enough to have space to slide but close enough to hit the front of the pack. This is a little bit luck based but as long as you don’t get to a round where the slide explosion is useless, you can try this a bunch of times in a game. This is also another achievement where an Insta-kill would be useful, either as an Elixir or random drop. You can also get this without unlocking the perk by setting Secret Sauce as your fourth perk, which gives you a random perk not equipped in another slot. If you're lucky, you can get PhD quickly. However if you're not so lucky, you may not get it until after it's useful. You'll reach level 42 long before getting all other achievements so unless you prestige or want to get this early, you shouldn't have to worry about the secret sauce method.
