"Cranked" and "Search and Rescue" will join the playlist in Call of Duty: Ghosts' multiplayer this year, offering variants on the game's team deathmatch staples. As discussed at today's multiplayer event in Los Angeles, in Cranked, a kill will boost a player's speed and other attributes, but it'll also start a countdown clock; get another kill before it expires or your player will be blown up.
Search and Rescue is a team mode that allows downed teammates to be revived. Players who shot down drop a dogtag; if a teammate picks it up, they'll be revived. If an enemy picks it up, they're killed.
