MW3 Zombies Take Up Arms Mystery Box Location

Take Up Arms is an Act 1, Tier 1 mission in Call of Duty MW3. This mission is made up of two objectives. The first one requires that you “Purchase a Primary Weapon from a Mystery Box”, while the second objective is to then “Kill 50 Zombies with a Mystery Box Weapon”. In this guide, we are going to show you how to get a Primary Weapon at a Mystery Box Location and complete the MW3 Zombies Take Up Arms mission.

Purchase a Primary Weapon from a Mystery Box MW3 Take Up Arms

The first thing that you’re going to need to do here is to find a Mystery Box and purchase a Primary Weapon from it. To do this, open up your MWZ map. You can recognize the Mystery Box pretty easily thanks to its unique icon. It looks like a white box with a question mark over it. So make your way to the closest one. We have marked a location of one of these in the screenshot below. What you then need to do is to open up the Myster Box and hope you get a Primary Weapon (that is, a weapon that goes into your primary weapon slot) on your first try. If you don’t get lucky right away, roll again until you manage to get a Primary Weapon from it.

Kill 50 Zombies with a Mystery Box Weapon

With a Primary Weapon gotten from a Mystery Box in hand, the next thing you then need to do is to dispatch 50 Zombies with it. And for this, it’s best to find a spot on the map where there are many of them. For example, at an Exfil point. To keep track of how many Zombies you’ve killed in MWZ, you can open up your map and see the counter in the top right corner. And once you have successfully completed this mission, you are going to get the Cryo Freeze Ammo Mod Acquisition and 1500 XP as your rewards.
