To obtain both blueprints you will need to complete every challenge in the Outbreak Event tab.
However, actually beating these challenges is a tricky task, not only because you’re required to play both Warzone and the new Outbreak zombies map. Those who battle through the new Outbreak Challenges will earn the Gray Matter & Teal Drop blueprints. This comes in the form of new Points of Interest (POI), zombies, and another collection of event challenges for players to complete. Along with new operators, weapons, multiplayer maps, and balance changes, the beloved Warzone game mode has also received some alterations. A new season of Call of Duty: Black Ops Cold War has released.
