Can I have the vmf to edit this map for my server/can I make edits?
-Unfortunately, no. Replacing textures and other things using Lua is okay.

How can I restrict access to one city?
-If you're a server owner, download this Lua script[drive.google.com] and put it in the lua/autorun folder on your server.
The command to put in your server.cfg on your server is sv_nycity, with one of these values:
0 = Both cities open, does nothing
1 = Central District only, blocks access to Union City
2 = Union City only, blocks access to Central District
For example, you would put: sv_nycity 1. Shout out to Xalphox for the Lua script.

To restrict access to a city without the Lua script:
-There are 2 buttons located here https://i.imgur.com/MJx3cVR.jpg and there is text above the buttons that says what they do.
-The button of your choosing needs to be pressed as soon as the map loads, before anybody has had the chance to spawn. (The Lua script does this for you right after a server restart.)

How long did it take to make this map?
-It took roughly 2 and a half years to make.

Can I use some assets (sounds, materials, models) from this map in my own map?
-Yes you can, but remember to say thank you. Assets under "unioncity3" in "models" or "materials" are 99.9% my own creations (excluding sounds, I have only edited them myself). Rest of the assets belong to other Source Engine games and I won't take any credit.
