Trench=Pretty cool. Big open board with lots of trenches and kind of a roman colusium in the middle of it. Could be a nice sniping board due to pillars to hide behind.
Rooftops=Not as good a board as I thought it would be. It's not very big and I played it for a few minutes, but I couldn't find anywhere to really get on a higher rooftop. Probably the smallest board of the 4.
Plaza=Pretty big board too. It's got a nightime setting, so that kinda makes it neat also. Lots of small passages and huge castle with a balcony that extends into the middle of the "town square". Looks like it will be good sniping from there
This board isn't bad though. It's got a huge gasplant inside and snow on the outside. Several staircases with a few floors inside the plant. Medium to large sized map.
Overall I like the maps, they look just as good as the regular PD0 maps and all have their own look and feel to them. 3 of the 4 maps are pretty big and I like those 3. The only small one and disappointment to me was the "Rooftops" map.
