Missions are one of the most essential Call of Duty features that help players unfold the story. Modern Warfare 3 Zombies is not an exception. Once you start grinding through the Zombies mode, you will eventually discover that the missions are the only way to explore the entire story. If you are curious to understand the entire story from the beginning, you have to go through all the missions, starting from Act 1.

So, going through the Act 1 missions, if you get stuck while trying to complete the Tier 3 mission, Freezer Burn, this guide will help you with all the necessary information. Before going to the process of completing the Freezer Burn mission in Act 1, Tier 3, players must know the objectives to get prepared.

Act 1 Tier 3 Freezer Burn Mission Objectives

Freezer Burn Mission Objectives

If you have been playing the game you are already aware that MW3 Zombies will force you to think strategically before jumping into a mission. This won’t be possible if you don’t know the tasks you need to complete. So, if you want to dive into the Freezer Burn mission, let’s check the objectives:

  • Slow 50 zombies with Cryo Freeze ammo mod
  • Slow 10 hellhounds with Cryo Freeze ammo mod

These two objectives are not complicated to understand, but they are indeed a bit tricky. However, a little help will solve all the problems. So, go through the next section for detailed information.

Steps to Complete the Freezer Burn Mission in MW3 Zombies

If you have noticed the two objectives, you will easily understand the primary task, which is to get a Cryo Freeze ammo mod. If you have one in your stash already, you can equip it and jump into the game to complete the mission. However, most players probably won’t have it. In that case, they have to get it in-game and then jump into the mission.

Acquiring ammo mod has a specific process and that’s a pretty random one. Once you spawn, you have to clear Aether Nests and Infected Strongholds. These locations have cache boxes that contain ammo mod, but not necessarily the one you are looking for. To be precise, you can get a single ammo mod several times. So, it’s pure luck to get a Cryo Freeze ammo mod. Players need to grind a lot to get a Cryo Freeze Ammo Mod. It can even take an entire game to get it.

Acquiring Cryo Freeze Ammo Mod

Once you get the ammo mod, equip it to your weapon and you are ready to start your mission. Now, again go through the mission objectives and you will understand that your objective is not to kill them, but to slow them by freezing them. As you shoot using the Cryo Freeze ammo mod, zombies will get frozen. But the problem is, not everyone will get this effect. You have to shoot and a random zombie will get frozen. Once they get frozen, you can kill them easily.

Both objectives can be progressed simultaneously as zombies and hellhounds generally spawn together. But we recommend doing them individually. While you can accept any Escort contract or other contracts to get a wave of zombies together, there’s one simple way. After you get the ammo mod, go to an exfil zone, better if you stick to a low-threat zone. As soon as you call for the helicopter, waves of zombies will spawn. Start shooting them with the weapon and you will eventually see zombies getting frozen for a few seconds. This effect will slow them and help you reach the target. Additionally, do it anywhere to see a group of zombies.

Once the first objective is done, it’s time to jump into the second one. The next one must be done in the medium threat zone or high threat zone as these two zones have hellhounds that players can use to complete the mission. Hellhounds generally don’t spawn in a low-threat area.

Freezing Hellhound

Navigate to the medium threat zone and you can choose an Aether Nest or Infected Stronghold for the hellhounds. You can randomly find them, but doing that will take a lot of time. So, target places where you can find hordes of zombies, and among them you will get hellhounds. As these hounds come, shoot them and the remaining process will be the same. Randomly a few of them will get frozen to help you reach your target. As soon as you slow 10 hellhounds, your mission is done and you will get the rewards.

Rewards for Completing the Freezer Burn Mission in MW3 Zombies

Calling Card

Each mission comes with rewards in Call of Duty games. From Calling Cards, to Free Perks, XP, and multiple other things players can get as rewards. MW3 Zombies is no exception. The more missions you complete, the more valuable items you will get as rewards. So, you will the below items after you complete the Freezer Burn mission:

  • Baseball Fan Calling Card
  • 1500 XP

Among these two rewards, the first one may not seem impressive to many players as Calling Cards are mere cosmetic items without any advantage to the battle. These items can be equipped to customize your profile. However, equipping these can show how much you grind. On the other hand, XP is one of the most required items in the game. Getting 1500 XP will help you level up and lot and unlock new items and perks.

These are everything you need to know about completing the Freezer Burn Mission in MW3 Zombies. This mission can be completed alone, but we suggest bringing a few friends as you must complete it in one go. Friends can back you up in every complicated situation and help you fight zombies and hellhounds. It’s not recommended to die in the mid-mission. Once you die, you will lose the ammo mod and have to start by finding it in the next game. This mission will take time as it will require you to grind a lot to find the ammo mod. So, when you get one, try to complete the mission in one go.
