I like the three new non-Zombie maps
Breach is a little bit dull. Fairly symmetrical areas on each side of central gateway. Around most of the periphery are various second story locations. Some sniping opportunities and don't stand outside for very long if you want to survive. Still, a decently large map. Sort of like Station but with second story access and no roof. And larger. And better.
Revolution is pretty nice. Buildings surround a central building and there are second story pathways over most of it. Cleverly placed sight lines mean there are few camping spots for snipers that can't be seen from more than one location. Pretty good sized as well. Center building has few interior walls and is for the brave and foolhardy. Outer buildings are a betty placer's delight
Battery is just excellent. Cleverly non-symmetrical. Main location fort has many non-obvious paths and hide spots. And there are two standing free towers which can only be accessed by open gangways, and are also connected to each other. Add in an amazing amount of eye-candy; there are just so many interesting things to look at, you'll get whacked often while sight-seeing.
Overall I rate this pack as the best of the three. I think Banzai might still be the best map, but Battery is in the top few easily.
