On the current map, it seems like we are at the tip of whatever continent/island that we are on.  I was wondering that maybe, all the tiles at the top of the map had the image and description of some sort of border.  Be it man-made or natural.  Probably adding both would make more sense. 

Also, I think that there should be areas in the game that would outline the difficulty of the zombies in it's area. 

Say a yellow color for lvl 1-10

an Orange color for lvl 11-30

and a red color for lvl 30+

Also maybe a Green Color for areas that human-controlled zombies have over-run and a blue color for human territories.

I like the idea of being able to see areas danger levels. However, a player should not always see this. You should have to go to an (HQ) and look at a special map in the HQ room. THis will bring up a clone of the map that doesnt let you travel but shows you the danger lvl of each space and area. Once you leave though its up to you to remember where they all were.

It would be nice for sometype of wall or explination for not being able to pass. Maybe in the future, there can be walls or zones that must be slowly broken open by players. Or if clans can build walls around there safe houses and players can attack these walls to get in.

I think this is an ok idea but there are so many different levels of zombies in each area that this wouldn't work very well.

I think it should be something not known because if you were to be wondering the streets if this was real you wouldn't know what zombies/living would be there or hiding.

Just my take on it.

Well in the end, Id just like a system in place that told you where people of low level and higher levels should be at, or where they can expect to see zombies of their level.  I think I speak for everyone when I say, those random lvl 30 hordes blocking quest locations meant for low levels is a problem.
