Gathering Schematics is a big part of Modern Warfare 3's new MWZ mode, letting you permanently unlock Wonder Weapons and consumables to bring into each game with you. Rather than having to find an Aether Tool at the start of a match to upgrade your weapon's rarity, you can bring one with you. Instead of having to purchase a Perk-a-Cola to get your ideal operator perk, you can simply craft one beforehand.
Since weapon rarity and Pack-a-Punch level disappear when you exfil, Schematics are the mode's true progression, letting you push further and faster into the higher threat zones with less prep time each match. These MWZ tips might also help you make some progress, but either way, here's how to find Schematics in Modern Warfare 3 zombies.
