A little AutoHotkey + Python (3) script for displaying a kill counter (odometer style) in OBS, or possibly other applications.
When you activate the hotkeys (Indicated in the .AHK file), it will either incriment, decriment, or reset (only the match kills) for the included data files.
I configured OBS to load the datafile as a text element on screen, which allows you to have a dynamic text element on stream.
Latest version of autohotkey! Latest version of Python (3) Make sure you have pythonw.exe associated with .pyw files!, Put all of the files in a folder and it'll "just werk™", NOTE: you can have seperate folders for seperate games, other counters.
