The multiplayer in Call of Duty: Ghosts features changes from that of previous Call of Duty games as some new mechanics have been added to it. Maps now have areas that can be altered or destroyed. There is a nuke-like kill streak reward, the KEM Strike. You can get the ODIN kill streak by either getting a certain amount of kills or you can get it by killing the top player on the other team and then completing various challenges after picking up a blue briefcase that is dropped. The sniper rifle scopes also have new "dual render technology" allowing the player to see around the outside of the scope (although blurred) when zoomed in. On October 3, a new multiplayer type was revealed, called Squads.
