Infinity Ward's latest tweaks to Call of Duty: Ghosts bring something over from Black Ops while farewelling a mode. But that's the official stuff.
Unofficially, Reddit user Osiris OP has posted up a screenshot showing what might be the titles of the new Ghosts maps: Battery, Rumble, Red River, and Dome.MP1st
points out that, "It’s worth pointing out that two maps titled “Dome” have been a part of the Call of Duty franchise; one in Treyarch’s World of War and one in Infinity Ward’s Modern Warfare 3. Also, as we previously mentioned, many users found Strike Zone from Call of Duty: Ghosts strikingly similar in layout to Modern Warfare 3′s Dome."

it's made clear that the title update which will go live for Xbox One, Xbox 360 and PC today, with a PS4 and PS3 on January 29, sees Black Ops' Gun Game mode coming to Ghosts. Making way for it is Heavy Duty.
