The map has walls with dotted blue lines.. At windows.. And dotted white at doors..

Is this a new rules way to signify the line of fire... Or movement are not blocked?

Without the new rules do you just treat them as standard walls?

As it is right now, without any special map rules or clarifications, those are just treated as clear terrain. They are definitely not walls, since there is no black line through them at all.

That said, and this is purely speculation, I have a feeling (as do many others, I'm sure) that this will change with the new rules. I would expect these to function like the doors and windows we've seen as special terrain on other maps, and will become a standard terrain features.

We agreed to play it as ..

windows = wall, does not block line of fire.
doors = wall, does not block movement.

It worked rather well.. for both sides..

I like it! (extra words to make this post long enough)

I believe that is how it is for the U.N. map.

Map Title: The Daily Planet
OPEN AIR ----------
Orange squares are Open Air squares. After actions resolve, if a character who can't use the Flight ability occupies an Open Air square, deal them 1 unavoidable damage, then that character's owner places them in their starting area. Non-held objects in Open Air squares are removed from the map.

GLASS WALLS --- --- ---
Glass Walls are walls that do not block line of fire. After an attack resolves, destroy all glass walls which had a line of fire drawn through them by that attack.

Map Title: United Nations Conference
GLASS WALLS ---------
Glass Walls are walls that do not block line of fire. After an attack resolves, destroy all glass walls which had a line of fire drawn through them by that attack.

DOORS --- --- ---
Doors are walls that do not block movement.

I thought about playinging it where the glass is destroyed, and also provided hindered line of fire until the glass is broken.. but it seemed to complicate more than it solved.

Simplicity and expedience of rules would make me drop that 2nd sentence.

Glass Walls
Glass Walls are walls that do not block line of fire. Movement and Lines of fire through glass walls are hindered. Movement through a glass wall will break the wall, The first space after crossing the wall is now hindering terrain.

.. this provides stealth support, the ability to break through the windows.
