Dyson, but you can make WTC Memorial right?Nope sorry can't have WTC in map for multiple reasons...
a) First of unrealistic, the map is set around 2010 9 years after the WTC collapse, showing a lot of memorials to 9/11.
b) May raise some ethical issues which I'd prefer to just be an extension of the mod in a mission
c) The area of map dedicated to GZ is nowhere big enough to hold all the buildings.
So I'm sorry for kinda just saying no, but it's not part of the freeplay sorry
And besides I think it'll be better to have a mission with it on, then freeplay without it, so you have the permanent scar, just as New Yorkers do...
It will be really cool!
