Facility is a blue nightmare of what the map used to be, in UC2 the top area was popular but in UC3 if you stick to the bottom levels, you will never find anyone.
Yemen however is amazing, lots of climbing, little blindfire, campers are easy to flush out, big but not too big.
I love the it, it's the best Uncharted 3 map made, hell, it's even better than some of the Uncharted 2 maps.
If you want to deal with people camping the towers, there's two easy ways, grenades (like most people do), or Cloaked+Monkey Man, and they'll never see you coming. Power Weapons are fine too, but you should pick one up if you see it, then the other team can't hoard them. Heroes do get the Mag first, but chances are it'll be some idiot who blindfires all 8 shots to get 1-2 kills.
If you like long range guns fights, the towers and any other upper areas are the best spots for kills. If you prefer mid-range, stick to spawn areas, the sides, and if you are on the alert for snipers, the middle area. If you enjoy stealth, there's many dark areas that can give you a good view of people that will pass by. If you prefer close-range/blindfire, then eject your disc and snap it in half, if not, stick to the stairway areas and corners. This map is perfect for all playstyles, which makes it the most balanced map in my opinion.
It's also a good map for Riot Shield users, though sadly I never see any.
