DupeNameGenerator
Oxygen Not Inlcuded mod that generates random names for your dupes rather than using the standard ones. Each dupe will get a name and surname or title. There is a 4% chance that a generated name will have a title instead of a surname.
Installation
Download the lastest version from Releases and extract into your Oxygen Not Included mod directory located at %USERPROFILE%\Documents\Klei\OxygenNotIncluded\mods\Local
If the folder \Local does not exist create it.
The final directory should be %USERPROFILE%\Documents\Klei\OxygenNotIncluded\mods\Local\DupeNameGenerator.
Start ONI, navigate to Mods and enable the DuplicateNameGenerator mod.
Customize names
In the DupeNameGenerator folder there is another folder NameLists that contains the list of names the mod uses to generate duplicant names.
Simply modify the lists to add more names, surnames or titles.
