I know it's late, but you need both the original They Hunger and the simple model pack.
If you want the Remod version, get They Hunger, ZikShadow's Remod and this remod.
For simple version:
Get They Hunger and unzip into hunger folder
Copy the simple version into the hunger folder and overwrite
Then you can play
