MW3 Zombies Freezer Burn Challenge Guide

Master the MW3 Zombies Freezer Burn Challenge! Learn how to slow 50 zombies and 10 hellhounds using Cryo Freeze Ammo with our expert guide. Get the best tips here!

Alright, let's break down the Freezer Burner challenge in Modern Warfare 3 Zombies. It sounds a bit intimidating, but it's pretty straightforward once you know what you're doing. Basically, you need to freeze a bunch of enemies using a specific type of ammo.

Here's the rundown:

1. You need to slow down 50 Zombies using Cryo Freeze Ammo.
2. You also need to slow down 10 Hellhounds using Cryo Freeze Ammo.

The key here is that Cryo Freeze Ammo. You've got a couple of ways to get your hands on it:

• First off, you can find it randomly by completing Aether Nests, Contracts, and just looting areas around the map. It's a bit of a grind, but it's definitely possible.
• Alternatively, you can get the Cryo Ammo Formula. If you manage to find this formula and successfully extract with it, you can then craft Cryo Ammo Mods in your pre-game lobby under the schematics menu. This lets you start your next deployment with the Cryo Ammo ready to go. Just a heads-up, you can only craft one of these mods every 3 hours.

So, as you can see, this challenge is all about patience and a little bit of luck with the loot drops. Ammo mods are considered rare, so you might need to play a few games before you find one or the formula. They often pop up as rewards after finishing contracts in those loot portals, or as drops from Aether Nests. If you get lucky and find a formula, make sure you extract with it! Then, head to your pre-game lobby, go to the schematics menu, and craft the Cryo Ammo Mod. Once you've got that, you can attach it to your weapon before you even drop into Urzikstan. Then it's just a matter of applying those frosty rounds to enemies until you hit the target numbers.

You'll also encounter Hellhounds as you play, but if you're having trouble finding them, try looking for the Hellhound kennels. That's usually your best bet for getting them to spawn. With these tips, you should be well on your way to completing the Freezer Burner challenge. Good luck out there, Demon Slayer!
