I'm taking a slog through Mutants and Masterminds 3e again. This time, I'm working on a character with a county-sized headquarters (Awesome headquarters with Grounds feature). In his backstory, the character had acquired himself several plots of land in Nebraska and managed to earn District status for them through shenanigans and malicious compliance. All the complications from this are fairly straight-forward, but I'm drawing a blank as far as making the Security and Defenses flow with that concept.
See, the Grounds feature states that Defense Systems and Security Systems extend through the area surrounding your Headquarters, and the Defense System feature states that it can be any attack effect with a cost no more than double the HQ rank. Keeping in mind that this headquarters is a populated county with its own problems, I don't want to have people blasted with space lasers for loitering, nor do I want a Mall Cop to smack a hover-tank with a nightstick. So, mostly for fluff reasons, I want to have a handful of different Defense and Security systems in my headquarters that are tooled to different potential situations; how do I do this?
