Online play retains much of what is familiar to you from previous Call of Duty games. Game modes available are Free-For-All, Search & Destroy, Demolition, Domination, Team Deathmatch, and Capture The Flag the returns and the action will take place across a number of locations based on the single player campaign. An annoying feature of COD 4 was that when a host left, the game ended. This is now fixed with in-game host migration, which should remove all instances of having to go back to the lobby and restart the game.
