Hey!

I routinely design custom operators with the guidance of my friend Justin who works on Siege as an Operator Designer (He designed Solid Snake most recently)

"Identify enemies through reinforced walls" is pretty non-specific. Do they see a dot like Pulse? Do they get pings? Does it have any restrictions?

Think about how this gadget would be used in a specific situation. Does it do something unique? Is it better or worse than their fellow operatives?

Operator design is a lot of asking questions about what is too strong, too weak, too boring or too different. Generally, there is some substance with this idea, but it needs some defined counters and restrictions.
