Do you remember Visor Tools? Well, I've got something much better for you. I call this one 'Enhanced Visual Overlay', as it completely re-works the entire overlay system. It's basically augumented reality for your average Civil Protection Unit/Overwatch Unit.
With this plugin, you'll feel like the terminator you've always wanted to be.
Side-note: This plugin is originally by Polis, however he has been banned and I cannot find any contact information for him. If you know how to contact him, please email me. I will be improving and maintaining this plugin unless he asks me to stop.
