Call of Duty: Ghosts will see the return of Modern Warfare 3‘s Dome map in the form of DLC, according to a leaked playlist.
The list comes from the PC version of the game, in which the map names appeared in a Moshpit playlist labelled “IW6 Daily Test” (spotted by “Denkirson“). The maps listed in the playlist were Boneyard, Dome, LUA_MENU_GAZA, Red River and Swamp. Now going on previous Call of Duty map packs, one of these is presumably a new Extinction mode map.
The playlist was pulled shortly after its discovery, so you won’t be able to find it now.
