MW3 Zombies is full of missions for you to complete as you progress through the story, and if you want to beat Act 2, you need to get through More Firepower. Luckily, completing can easily be done in one deployment.
More Firepower Mission Guide in MW3 Zombies
To complete More Firepower, you need to Pack-A-Punch your weapon to level 2 at any of the Pack-A-Punch machines in the medium or high-threat zones. You won’t be able to upgrade your weapons to level 2 in the low-threat zone on the edges of Urzikstan, so make sure you go into the deployment with the higher tiers in mind.
If you go in without an Aether Crystal, you will need a total of 15,000 Essence to complete the first part of More Firepower. Level 1 costs 5,000 Essence, and level 2 is an additional 10,000 once you reach the medium-threat zone. Getting level 3 will cost 15,000 in the high-threat zone, but you won’t need this upgrade until the Most Firepower mission in Act 3.
More Firepower Mission Objectives:
- Pack-a-Punch a weapon to level 2.
- Kill 75 Zombies with a Level II Pack-A-Punched weapon.
- Kill a Special Zombie with a Level II Pack-A-Punched Weapon
For those of you with plenty of materials in your stash, you can spawn into MW3 Zombies with a Refined Aetherium Crystal. This consumable will automatically boost your weapon to Pack-A-Punch level 2, and then you can finish the other two steps. Even if you only have a Raw Aetherium Crystal, that can instantly get you to level 1 and save you an extra 5,000 Essence.
With your weapon Pack-A-Punched, make sure to kill 75 zombies and a Special Zombie before you exfil so you can complete the full mission. Once you hit Act 3, you only have to do this one more time.
Sometimes, it helps to know where the Pack-A-Punch machines are before you go running around Urzikstan.
