For the first time in Call of Duty history, players can find easter eggs on the DLC Multiplayer maps and earn bonus XP for completing the passive "Egg Hunt" operation. Each of Onslaught's four DLC maps has one "Extinction Egg" hidden somewhere in the map, and must be shot once to count towards the task. Once all four are found, players are rewarded a bonus 2000XP. This can only be done once, but it also must be done in a public multiplayer match, not in a private match or Squads.
- Fog: Go to where the dark circle and the small waterfall is. Looking down west into the pit next to the waterfall will be the red-and-yellow Extinction Egg.
- Bayview: At the south edge of the map, of you look east at the dock off the map while crouched, you will see an upside-down dome shaped Extinction Egg hanging from the bottom of the dock.
- Containment: Go to the white and red-striped building on the northwest corner of the map, go up the stairs and look left, northeast, out the window. Behind the green building with "Transmission" on it is the Extinction Egg on top of the small white red-roofed building.
- Ignition: After the rocket explodes and the piece of the fuselage crashes onto the map, go down the middle tunnel and the Extinction Egg (and its tentacles) is sticking out of the west wall.
Additionally, when players destroy the first hive in Nightfall after the Eggs are found, they get an additional 10,000 XP on Extinction.
