Modern Warfare 3 - Defeat Greylorm for a Chance to Get the Schematic

Greylorm is a hidden boss in MW3 Zombies that can only be fought inside the Aether Storm after the match time ends. To fight this boss, you will need to collect 4 Calibration Data USBs and place them in the Refractor terminals inside the Aether Storm.

After you kill Greylorm, a Reward Rift will spawn that has a chance to contain a Flawless Aetherium Crystal Schematic, a Scorcher Schematic, or a Legendary Aether Tool Schematic.

Do note that these are not guaranteed drops. You will likely need to beat this boss multiple times to get all possible Schematic drops from it.
