Anyway, I've played some combat chars. Who in the event of a brawl are probably gonna step in or get the frick frack out depending on who. Now, I've also played some non-combats who would either run, or if there's no time or way out to run, hit the deck. However, hitting the deck isn't mechanically feasable (Save pose/tp which don't save your ass)
It's already been confirmed a take cover command has been suggested and the staff have thought about it. But here's how I see it working if we were to get it.
Dense/undense surfaces. If ya hide behind a couch, you're not blocking bullets. HIde behind a chrome bar? Maybe a bit safer. Bullet caliber/shrapnel size determines penetration of surface (This should be another suggestion ik)
A basic take cover command, where you'll 'run' into the nearest cover in your room. However, you could also specify a cover, cover would put you behind a specific item in that room. Increasing your chance of being hit while you shift to the cover that isn't nearest to you, since you gotta look for it, but adding the guarded+ bonus against ranged of taking cover.
