Well after a bit of time off from my project I have gotten back to it. mostly thinking and a bit of work I have decided to make A few Modifications to my board. First off I had to redesign the first bit because it had some meausurement inaccuracies leading to some odd bits. so I fixed it up and it gave me some more space so I added a subway entrance and a snack shack.
And this is the second part of the board. Its only dominating feature is going to be the construction site.

And these are both boards together.
for the construction site Im going to steal whoevers idea it was to make nuked building shells out of milk crates and instead of making them blackened and broken ill make it more metally or redish coloured to look like a building in progress.
So I was thinking wouldnt it be interesting if you could go underground in the games and then I thought why not so I stole the idea of having a sub level to the gaming board. sewers, basements and a underground subway.
So Im going to have my top level of buildings and then the manholes will lead into sewers that goes all the way to the ocean bit and also has a few walls drilled out/knocked down by survivors to get either in or out of basements. The subway stations will go across the board and the tunnels will be linked by sewer entrances. The sewers will be a mix of tunnels as wide as the road and as thin as the footpaths in order to allow the zombie players to be able to encircle and attack the the human player.
The basements will be as tall as another floor on one Of Matakishi's inner city buildings meaning I can comfortably fit some scenery in there. This will all be Cut into a pretty thick piece of blue or pink polystyrene. So this also means I can create a dock thats actually tall and has those wood things whatever they're called that has people fishing off them going into the water instead of just a 3mm piece of MDF ontop of another piece of 3mm MDF coloured blueish.
Anyway Thats all I have done and as usual I lack the vocubalary to sufficiently explain the situation so what do you guys think.
