Call of Duty Black Ops: Cold War introduced one of the biggest shakeups in spin-off mode history to Zombies, adding operators, weapon rarities, starting loadouts, and more. Some of these changes include choosing your own ammo mods in the Pack-a-Punch Machine. This is a mechanic that was previously only randomly assigned.
These ammo mods are fully upgradable, with Atherium Crystals that unlock 5 tiers each, making these ammo mods pretty powerful and turning them into elemental zombie slayers. Naturally, the internet demands that these attachments be ranked with clear winners, so here are the best ammo mods to help you fend off hordes of undead in Cold War Zombies.
Updated by Axel Bosso on April 9, 2023. It seems that there are still many players like you who are slaying zombies in Call of Duty Black Ops: Cold War. That’s why we wanted to update this list and take another look at the best ammo mods to check out the links and images.Good luck against the undead!
Five napalm burst
Despite several buffs that nearly double the damage, Napalm Burst has never been a popular pick among the zombie community. But you don’t have to leave the napalm burst alone. When fully upgraded at tier 5, affected zombies explode, spreading a burn effect to 5 of his enemies nearby. This is a much wider range than Dead’s Wire after being weakened.
Napalm Burst also has a significant cooldown, and the lingering burn damage eventually acts as a one-shot kill until reaching higher rounds. However, the big weakness of this ammo mod is its effectiveness against special enemies. Against hordes of regular zombies, however, Napalm Burst basically acts as a powerful pack-a-punch that can easily clear paths. I feel satisfied.
Four dead wire
As any OG player knows, setting Dead Wire this low is a pain. As the name suggests, Dead Wire deals electrical damage to zombies and was a key part of all Cold War Zombie overpowered loadouts at launch. Tier 5 upgrade chains electricity to multiple zombies, essentially turning any weapon into his Wunderwaffe DG. -2.
Sadly, Treyarch has taken a close look at how OP Dead Wire works, and the ammo mods have been devastating in terms of damage, length of effect, and importantly, how many zombies the ammo mod spreads at tier 5. has been greatly weakened. Dead Wire is still the only ammo mod that gives Megaton extra damage, so while it’s still used on certain maps, it’s nowhere near the powerful weapon it once was.
3 shutter blast
Added in a post-release update, Shatter Blast deals explosive damage, with each bullet detonating for additional damage and potentially destroying all armor affected. So it’s ideal for dealing with hordes of armed zombies in later rounds, or Panzers in outbreaks.
You’ll have a hard time finding better ammo mods to grind out full damage and rounds, but there are some downsides – explosive kills that don’t count towards camo challenges, simply knocking over zombies instead of killing them explosions, etc. Slow charging time. Recommended as a secondary weapon as an emergency backup, or for those focused solely on high round grinds.
2 to freeze
Cryofreeze, which inflicts frost damage, may not be as powerful as Shatter Blast for blowing hordes away, but it has far more uses in a variety of ways. Cryofreeze, which activates every 0.8s at Elemental Pop Tier 2, has the shortest cooldown and is best used by SMGs, Assault Rifles, or every day Shotgun and sniper bullets.
Not to mention, Cryofreeze freezes and slows down all enemies, including special ones. The ammo mod gives a bonus 10 points for every time you slow down a zombie, does extra damage to frozen zombies, contributes to camouflage challenges, and is very useful for managing and controlling zombies. Whether it’s an outbreak or a traditional round-based map, you can’t go wrong with Cryofreeze.
1 Brain Rot is the best ammo mod in Cold War Zombies
A consistently popular pick since its release, Brain Rot turns the undead against you and starts killing other zombies instantly. A brain-rotten zombie usually kills 4-7 zombies, but you only need to kill 5-6 undead to clear the whole round.
However, what makes Brain Rot the best ammo mod in Cold War Zombies is that it’s a tier 4 upgrade that can transform special (but not elite) enemies as well. That means soon he’ll have Manglers, Mimics, and Tempests all fighting by your side. The Tier 5 upgrade means that brain-rotten zombies explode when they die, transforming three other nearby zombies and starting a huge chain reaction.
It still has its shortcomings of less points and less weapon XP for kills with the Brain Rot, but it’s more than compensated for by the huge return on investment.
