Call of Duty: Black Ops 4

This achievement is actually really easy to obtain. You have to re-pack-a-punch a weapon until it gets the Brain Rotter special ammo type. This ammo type works a lot like the old ammo type Turned did, by making the zombies attack each other. Shoot it at tigers and make them attack each other. When one dies you get it.


To unlock Pack A Punch, you must go to a gods temple (The area where perks are found) and activate the gong on the top floor of each one. Doing this will spawn that gods champion into the game. When you kill them, it will drop a head for you to pick up. Collect all four and make your way to The Temple (bottom area) and place each head on the spikes found by the pillar in the middle. Once all 4 are in place the Pack a punch machine will appear.

The first time it costs 5000 points to use. After this it's 2500 each time to obtain/change the ammo type. Keep using it until you get the Brain Rotter ammo type. Then simply find some tigers and shoot them until that attack each other.

Doing the first 3 banner challenges will get you a PaP gun, so you only need the 2500 and hope for brain rot.

The absolute easiest way to do this is to start a solo zombies game on IX:
- First cut down a banner flag in the arena at the beginning
- Complete the first 3 challenges to get the Z-Harmony PaP Pistol as a gift from the Gods in the Challenge Podium.
- Visit all 4 towers, ring all 4 gongs, kill all 4 challengers, and feed their heads to the PaP Altar in the Temple area to open the Pack-A-Punch.
- Pack a Punch the Z-Harmony until it receives the Brain Rot ammo type down in the bottom right. There are 4 ammo types and there is some luck required. You should be able to PaP the gun at least 3+ times before round 9. If you don't have enough money to get one before Round 9, restart the process. The reason we use the Z-Harmony is because it will cost only $2,500 to PaP and get an ammo type instead of $7,500 ($5,000 + $2,500) for a normal weapon. You will have more chances at the ammo type we need for less money.
- With a PaP Z-Harmony that has the Brain Rot ammo type, begin Round 9 upstairs in the arena area if possible. Tigers will begin spawning from the cages, and shooting them can cause them to convert to a friendly tiger. Be careful that you dont kill them accidentally with a headshot, and the brain rot isn't guaranteed, it's still a random roll. Only tigers spawn in this round, so if you brain rot one, they will attack another tiger, killing them and gaining the achievement.

So to start off simply you must be playing 'IX' and complete the God's 4 challenges to unlock the Pack-A-Punch. You then must re-Pack-A-Punch a weapon until it gets the accompanied power 'Brain Rot'.

This can be done by Pack-A-Punching a gun and then doing so again until the boost is received. You may also choose the easier option which is to re-Pack-A-Punch the gifted pistol that is given to you from completing the first 3 challenges from the High Priest.

Once obtaining a Pack-A-Punched weapon with the 'Brain Rot' power, you must then "turn" an undead tiger (have it glow green and fighting for you) and have it slay another undead tiger.

This took me about 10 killings of the tigers as in that 10, I had turned a tiger but it died before killing another tiger and I then had to get another. Thus, it should not take too long. A tiger round will make this easier.

To help I have attached a video that I myself recorded of myself with the Pack-A-Punched gift pistol with the Brain Rot boost that turned a tiger and killed another for the achievement.

Hope this helps!

Call of Duty: Black Ops 4 Here Kitty, Kitty Achievement Guide

For this I recommend that you try and complete your first three challenges. You can get these by knifing one of the flags in the spawn area.

From what I've played so far they have been the following for me, and the order of them will change from game to game.

Knife kill 13 zombies,
Get 6 equipment kills,
Get 10 Kills with your special weapon,
Get 5 headshot kills in a row,
Slide under the Blade Trap without taking damage.

Once you get the Packa Punched Strife from the third challenge you will want to start opening up the map and go to the four Alter Rooms and press on the Gongs to spawn the champions.

The Rooms are as follows....

Ra Altar Room
Danu Altar Room
Odin Altar Room
Zeus Altar Room

Also pay attention to the top left of your screen as it will tell you which area you are in.

Upon killing each champion they will drop a zombie head, once you have all four heads you need to head to the Pack-a-Punch room which is called the Temple and place them on the spikes poking out of the floor.

Then you will need to spend 2500 points to get an random effect on your Pack-a-Punched weapon, the effect you are looking for is the Riot Man. Once you have the Riot Man on your weapon of choice, you need to shoot a Zombie Tiger with it and the tiger you just shot at will start attacking the other Zombies/Tigers.


Hope this helped.
