Going to be boring and say all of them, until I've had chance to play them and see how well they flow
Pharaoh - An abandoned archeological site of an ancient Egyptian palace. Those most adventurous to explore this multi-level map will be handsomely rewarded with its deepest secrets.
Departed - A rural Mexican town amidst the Dia de los Muertos (the Day of the Dead) celebration. Complete a Field Order to unlock the Death Mariachi - armed with dual-wielding pistols that turn downed enemies into your own squadmates.
Mutiny - A pirate hideout in a secretive Caribbean cove. This eerie map includes an hauntingly unique killstreak: an escort of ghostly pirates to send your opponents to Davy Jones' Locker.
Favela - A refreshed version of the fan-favorite Call of Duty®: Modern Warfare® 2 map. Return to Brazil to fight on the connected rooftops and narrow passageways.
The maps are fine with me. Just sharing.
One map that I like the most is departed. I like shooting all the chickens there for fun!
And the colors are absolutely lovely.
