Schematics are required if you plan on crafting any items outside of your deployment in Modern Warfare 3 Zombies. Actually finding them is an entirely different story though. This guide will go over how you can get them for yourself.
How to Get Schematics in MW3 Zombies
You can earn Schematics by completing contracts and searching the Reward Rifts that appear at any level on the map. There is a small chance that these recipes can appear in Aether Chests as well, but in my experience, I have only found them in the rift orbs. Contract types themselves won’t make a difference in the loot you get in the end.
