Won't affect outlines added after this mod was released.
Removes (almost) all outlines from the game. You ever played Left 4 Dead 2 realism mode? Yeah, it's something like that. If you want extra realism I would recommend combining this with the Muted Stealth mod to remove stealth indicators. Good luck!
If you have my other outline mods and don't want to delete them/move them to try this out you can rename the .pak file to "zNoOutlines", this will force it to load last and override the other mods.
