The Cage is a utility in Call of Duty: Advanced Warfare on the Exo Zombies map Carrier. It costs 1000 credits to use, and is part of the Easter egg Flotsam & Jetsam. In order to gain access to the cage, the player will have to destroy a flying drone, like the one that can be seen carrying power-ups after teleporting. After destroying this particular drone, a lever will be placed in the player's inventory. They will need to proceed to the lockers. After activating an audio cue, the player can go to the Moon Pool area, and insert the lever into a panel, which will allow the player to activate the cage.

The player then needs to activate the cage, and kill a large number of zombies that are over the pool (thus putting blood into the water below). Soon after, a shark will appear. It is at this point the player must activate the cage a second time (one needs to have fished a red fish for this next part), and go into the cage after it drops into the water. Having the red fish in one's inventory, the shark will approach the player, and the player can swap the fish for an eyeball inside the shark's mouth. The cage will rise out of the water. After this, the player can access the locker previously visited, and continue towards the end of the Easter egg.
