So Magma, the map of fire, well lava, is actually a pretty fun map. Set in Japan, with buildings and a subway train to one side. Lava is placed in various parts of the map and the fact the lava can kill your ass can make this map pretty intense. There's some nice bottle neck areas to nail people running through and nice hiding places to have full on shoot outs.
The next map, Encore, a small to medium size map, set in a amphitheater with long walk ways that lead into small buildings. There's also the wide open of the stage with a king of the hill feel. It's a fun map, but you get stuck in a few areas like a cluster, at times respawns are too close to the same area, so deaths can be many.
The third map, Vertigo, is my wife's favorite map, not really. This map is set on a roof top(COD standard) kind of a fast paced map, you keep moving in a circular direction. I like this map with the many corridors and and cover, but watch for the head gliching and the campers sitting in corners. I wish there would have been more higher levels to snipe from.
Then there's Studio, aka Firing Range, what's there to say? It's a remodeled retro map. One of the funnest maps from the original Black Ops. Plays pretty much the same, fast and deadly. So we had a good time playing the new maps and will look forward to the next map pack.
The brew I chose to drink with the new maps comes from Avery Brewing Co. out of Colorado. Hog Heaven barley-wine. 9.2% abv. Almost too drinkable, the color is deep amber with a thick tan foam and a nice hoppy aroma. The flavor starts with an intensely rich hoppiness right from the get go which blends well with the alcohol level and ends with a rich sweet caramel finish. I've had this brew a dozen times and will enjoy many more. This brew would also pair well with Skyrim and Dragon Age.
Side note: I haven't played the Zombie map yet but I will let you know.
