Kincaid has a stunt called "Shoot and Move" it reduces penalties to rolls do to him moving while wielding small caliber fire arms by 2.
I thought you could only use 1 supplemental action per round (gaining you a -1) and moving a zone counted as a supplemental action. No where does it explicitly state in the rules that 1 supplemental action per round is the limit, but it also doesn't say anything about additional actions being cumulative.
Just wondering if Kincaid's stunt is from a previous build of the system or there is something I was missing there.
