Game itself might be an overrated mess, but holy hell, if those hitmarkers aren't sexy.

Instructions inside the archive, but if you just want what you see on the screenshots, just throw "Overwatch hitmarkers" into mod_overrides and you're done.

But I also included 3 different colors and 7 different sizes, so pick whatever you're comfortable with. And even version for Enhanced Hitmarkers mod, because why not.
