The Extra Life is an item that can be obtained in the Dead Ops Arcade. Upon grabbing it, you will receive a, what else, Extra Life. One of these will appear every time a player earns 200,000 Points, and only that player may grab the Extra Life. Rarely, they will appear after a round is completed. Once an Extra Life is lost, you will drop some iof your points in gem form. Other players may grab it while you are respawning.
When a player runs out of lives, it is game over for them. However, if another player has more than one life left, he or she will be forced to give the lifeless player one of their Extra Lives. Once every single player is out of lives, it is game over.
The Extra Life looks like a floating person. The aurora will be the color of the player that is able to grab it.
