I used the SoD Tools to extract the game's files but I don't know what files I have to change to get the effects I'd like.
I'm trying to lower the amount of zombies that spawn, the amount of time it takes for a mission opportunity to disappear, the size of safe zones and if possible the amount of time it takes for temporary safe zones to disappear.
I've found two zombies.xml files in gametokens with density, e.g., Residential.Density but I don't know if they're the ones I want to change and which of the two files I need to change. I found a few missions.xml files that had OpportunityTimeout in them but I don't know which xml file I need to change and if I can change all OpportunityTimeout variables or if some of them need to be unchanged.
I haven't found anything for the size of safe zones or the amount of time it takes for temporary safe zones to disappear so far.
