Requirements:
If you build your HS2 setup from scratch you need:
-Bepinex 
-Bepis Plugins for HS2
-Resource Redirector 
-HS2API 
-HS2ABMX 
-HeadBundleRedirect for HS2 (check this if the makeup is misaglined)
If you use a repack then it *may* have all of them installed already
DX DLC Recommended (probably even required)

How to use:
Just drop the mods and UserData folder to your HS2 folder (no need to extract the zipmod file)
Load the included card then modify it if you want, I do not suggest building the character from scratch
Card with "Thick Neck" on its name has neck modified using ABMX; looks more accurate IMO but might cause issue
If that happens or you don't like how it looks, load the normal one so you don't have to reset ABMX back yourself
Limited customization, see below

Limitation:
-HS2 ONLY! Not tweaked or tested for AI as I don't have that game anymore
-No bones framework (for now) meaning limited customization, and compatibility with other hair if they clip
