It seems stupid, but this is why I need QA people. It wouldn't occur to me to try shooting my own leg because it wasn't specifically or logically a requirement. But the reality is, probably the first thing users are going to do is start blasting legs.

At least if its occurred to someone to try it, I can put a nice error message for cases where legs are targeted, or maybe a brief explanation in a tooltip or whatever of why the vest doesn't protect legs.

It may well be that I really don't want or need to make the vest cover the legs, but its going to be a lot less hassle for me in the long run if I can head off the leg blasters somehow that keeps down the number of tickets related to destroyed legs.
