I miss the role where both made their threshold 3 surprise test, but whatever. Have it your way.
Kynos has probably lower edge than him, so he shoots first:
Defense:
5d6t5 3I already rolled my shot to disable the car.
Next action is to move out of sight and change magazines to normal ammo.
Being stealth while doing that:
Stealth:
11d6t5 5[/spoiler]
Kynos cursed inwardly again. Somehow those two guards had sensed his incoming shots and thrown themselves out of the way. Now he stood in a hail of bullets. Ignoring most of it, despite a few of them actually brushing against his armor he set his shot into engine block of the car and stepped into the alley next to him, moving at a steady pace back toward the next crossing alley and back to the open window.
