I don't know much you know about modding, cause I haven't seen you here before, so I'm gonna tell you how to mod step by step real quick. (just so there's no confusion). First, download Gibbed Disrupt Tools here, version b38. Once you've extracted it, go to your patch file where ever it's stored, drag it into "Gibbed.Disrupt.Unpack.exe" and it will spit out an unpacked version of your patch, allowing you to see all of the files. Next, go into generated, then databases, generic, and find "civilliandensity.lib".Once you've found that, drag it into the "Gibbed.Disrupt.ConvertBinaryObject.exe". This will spit out an unpacked folder at the top or bottom of your file list, and a "civilliandensity_converted.xml". Open the folder and there will be files you can edit. Some of them may be gibberish upon opening them (I'm not for sure if they will be). If they are, come back and ask how to convert them (quite frankly I'd like to know the same).
