Call of Duty: Black Ops 4

One of the two most annoying achievements for the completion, you must unlock all of the above characters, and some of them are tough. They all require you to obtain an item, some of which are rare spawns, complete a task then finish the match with the item still in your inventory.

Some of these are linked to the spawn of Zombies on the map. Zombies spawn in two random places at a time signified by a blue light in the following locations: Asylum, Graveyard SE of Asylum; Nuketown Island, Diner NE of Nuketown; Boxing Gym in between Turbine and Fracking Tower; Lighthouse and the Farm by Firing Range. You can land at one of those locations and hope zombies spawn there or head towards the light once it shows up. Zombies drop items upon dying, and has a chance to drop a character item. Once you kill all the zombies in a location, the mystery box will open which will contain a few items and possibly a character item. Once the box is emptied or is consumed by the storm, it will despawn and respawn somewhere else. Only one character item drops per round of zombies, and while this hasn’t been confirmed, it is likely that some of these items are on rotation (ie the likelihood of them dropping fluctuates), so if you’re having absolutely no luck even finding an item try again another day.

These characters are also boostable (to an extent). If you queue at the same time as somebody else in the same region, 8/10 times you'll find each other. From here you can look for the items together, get the specific kills on each other or help each other survive. I never got banned while doing this but I can not guarantee that you won't be.

As a final note, any alternate versions of these characters such as the IX variants are not required for this achievement, nor can they substitute them (for example, IX Shaw does not count for Shaw).

Below is a list of all characters, their requirements for unlocking them and tips where necessary. Any position finishes are listed as Solo/Duos/Quads. All items must be kept in your inventory until death/victory.

Bruno: Obtain the Mug Shot item out of a supply drop. Down a player with a melee attack, then finish them by any means. This can be tough in the regular modes, since only a few supply drops spawn per match and they draw a lot of attention and even if you do get it, it can be tough to down someone with a melee weapon. Your best bet would be to doorway camp as melee weapons are one shot downs, or you can boost it. If the Alcatraz map is available, it is much easier here as the item spawns in regular supply stashes. A lot of the prison is close quarters and you have people redeploying with just a pistol so it's easy to catch someone out.

Diego: Obtain the Pulp Magazine from a zombie. Down an enemy with a headshot, then finish them off by any means. Another one that’s easier with boosting.

Scarlett: Obtain the Racing Goggles and Scarf from a zombie. Down an enemy with a vehicle, then finish them off by any means. This one isn’t too bad once you get the item, drive around and you’re sure to find someone to run over. More experienced players will be good at dodging vehicles but you’re sure to catch someone out eventually, of course this could also be boosted.

Shaw: Obtain the Alchemist Set from a mystery box. Down two enemies with Acid Bombs or Wraith Fires, then finish them by any means. In my opinion, this is the hardest one to do without boosting, since they’re pretty hard to get kills with unless you catch someone unaware or stick them with an Acid Bomb, on top of this being a harder item to obtain in the first place. I strongly suggest boosting this with two other people.

Dempsey: Obtain the Juggernog Bottle from the mystery box or the Diner in the Nuketown Bunker. Down a player with a grenade (frag or cluster) then finish them off by any means. Since there is a regular spawn for this, you'll have more frequent chances to get this so you may not need to boost this one. However, this fact always makes it the quickest to boost so it’s up to you.

Takeo: Obtain the Letter to the Emperor by interacting with a typewriter in the Asylum office, the Boxing Gym office or the penultimate floor of the Lighthouse. Do not use any equipment after picking up the letter. Finish in the top 15/8/3. This is one of the easier characters to unlock and won't need to be boosted. If you’re not confident getting good placements yet, take your chances hiding until the required people are left.

Nikolai: Obtain the Russian Tanker Hat item by throwing a Monkey Bomb at the Mausoleum gate on the north side of the cemetery. Finish in the top 10/5/3. Another fairly simple one that can’t really be boosted. The Monkey can only be found in areas where zombies can spawn. Once you have it, it's just a matter of surviving.

Richtofen: Obtain the Blood Vial by sacrificing either Dempsey's, Takeo's or Nikolai's item while playing as their character in the Blood Fountain in the center of the Asylum. Finish in the top 5/3/2. Takeo is the easiest for this one, as you can just grab the letter from the Asylum office then go grab the vial. The placement requirement is the most difficult thus far but as you get better at the game, you'll get it eventually.
