I don't like most Attack/Defend maps because of their design being based around chokepoints and the defense team being largely favored. This map changes quite a lot of that with a lot more accessible flankroutes for the offense team, with some spots on the map having glass windows to show the red team that blu's on their way to cap the point. The aesthetic here is phenomenal with the amount of details put into it, especially the helicopter pad for the first point.
You did an excellent job making Attack/Defend work on a map like this.
