Jingle Hells in *Black Ops 6* isn't just a holiday-themed reskin of Liberty Falls; it's a complete overhaul of the progression and upgrade mechanics. Here's your comprehensive guide on how to upgrade your weapon and obtain Ammo Mods in Jingle Hells within *Black Ops 6* Zombies.
How To Upgrade Your Weapon in Jingle Hells in Black Ops 6 Zombies

In the standard *Black Ops 6* Zombies mode, players typically upgrade their weapons using Salvage at the Arsenal Machine. However, in Jingle Hells, this machine is notably absent. Instead, players must seek out Aether Tools to enhance their arsenal. Aether Tools come in various color-coded rarities and, when used, will elevate your weapon to match the tool's tier. For instance, a Purple (Legendary) Aether Tool will transform your weapon into a Legendary rarity.
To acquire Aether Tools in Jingle Hells, consider these strategies:
- Visit the Church and aim a grenade at the zombie head perched on the spire. A successful hit will make the head vanish and cause zombies to plummet from the sky, dropping loot upon impact. One of these will be an Aether Tool, with higher rounds yielding rarer tools.
- Unlock the Bank Vault and use Loot Keys to access safety deposit boxes, which may contain Aether Tools of varying rarities.
- Participate in S.A.M. Trials and strive for the top reward tier, as these trials can drop Aether Tools.
- Employ a Hidden Power GobbleGum to instantly upgrade your weapon to Legendary Rarity.
- Keep an eye on weapons from the Mystery Box, Wall Buys, and Holiday Presents, as their rarity increases with advancing rounds.
How To Get Ammo Mods in Jingle Hells in Black Ops 6 Zombies
In Jingle Hells, the only available Ammo Mod is Cryo Freeze. This mod drops as a consumable item ready to be attached to your weapons. The primary source for these Cryo Freeze Ammo Mods is opening Holiday Presents, which yield higher rarity rewards as the rounds progress.
Here are the methods to obtain Holiday Presents:
- They may randomly drop upon defeating enemies.
- The Naughty or Nice powerup, resembling a stocking, can also drop them. Collecting it will display either a "Nice" or "Naughty" banner on your HUD. The "Nice" banner will grant multiple Holiday Presents, while the "Naughty" one will spawn numerous vermin enemies.
- The S.A.M. Machine, when it appears in Jingle Hells, will spawn several Holiday Presents around it.

How To Get Equipment and Support in Jingle Hells in Black Ops 6 Zombies

Similar to the Arsenal Machine, the Workbench is also missing from Jingle Hells, preventing players from crafting equipment or powerful Support items like Chopper Gunners, Mutant Injections, or Self Revives using Salvage. Nonetheless, there are alternative ways to obtain these crucial items:
- Equipment can drop as loot from vanquished enemies.
- Holiday Presents have a chance to contain equipment.
- Support items can be found as loot from defeating Special and Elite enemies.
- S.A.M. Trials can reward both equipment and Support items.
- The Bank Vault's Deposit Boxes may contain equipment and Support items.
These are the key methods to secure Weapon Upgrades, Ammo Mods, equipment, and Support in Jingle Hells within *Black Ops 6* Zombies.
