New Environments ( for next island?.. 
) My requests …examples.
Railway and railway stations.
Shopping centre… multi floor and under ground car park.
AND
destruction able environments… I can hide behind a wooden fence and bots will be blasting away from the other side… and there is no effect to me ?
They would need to change the game engine for that, its a NO GO.
BUT.
New buildings sure.
ALSO:
There already are a postal office and a fire department in Östervik.
But I know what you mean… Enterable, with details,… 
Yup, Being able to enter the building.
Sadly I don’t think this will happen, thinking of all those retroactively blocked off buildings all over the map…
