Firepower MW3 Zombies mission guide

Firepower is a Tier 1 mission in Call of Duty MW3 Zombies under Welcome to Operation Deadbolt Act One. Since this mission involves leveling up a weapon with Pack-A-Punch, you need to know all the methods to complete this activity. There are also a few items you can use, like Raw Aetherium Crystals, to instantly Pack-A-Punch upgrade on any weapon. The mission objectives are as follows:

• Pack-A-Punch a weapon to Level 1.
• Eliminate 50 Zombies with a Level 1 Pack-A-Punch Weapon.

How to Pack-A-Punch to level 1 in MW3 Zombies

There are two easy methods to Pack-A-Punch any weapon to level 1 in MW3 Zombies. The first method is straightforward, as you'll just need to find a Pack-A-Punch machine and use Essence (in-game currency) to level up the weapon. This can be time-consuming, however, as you'll need to gather a lot of Essence by looting and completing contracts. Check the image above to see how a Pack-A-Punch machine looks in-game.

The other method to get a Pack-A-Punch upgrade for weapons is to use Raw or Refined Aetherium Crystals. These two items can be farmed by completing contracts, capturing Aether Nests, taking over Strongholds, and other similar activities. Once you've found a Raw Aetherium Crystal, use it to Pack-A-Punch your weapon to level 1. Check the image above to see how this item looks in-game.

Eliminate 50 Zombies with Level 1 Pack-A-Punch Weapon

After getting a Pack-A-Punch upgrade on your weapon, you'll need to eliminate 50 zombies with that gun. The easiest way to do this is to visit an Exfil Point on the map and call for the chopper. Calling for an exfil will cause tons of zombies to spawn in the area, and you can easily kill them with your upgraded weapon. You can also repeat this process by calling down the Exfil chopper to level up all your guns. I did the same with my AMR9 SMG to level it up quickly.
