Stun guns, creature abilities, the stun power, electrical hazards, or other shocks to the brain or nervous system make a character essentially helpless until they manage to shake it off.

Stunned characters:

• Are Distracted (this is removed at the end of the victim’s next turn as usual)
• Are Vulnerable (this remains until they recover from being Stunned)
• Fall prone (or to their knees, GM’s call)
• Can’t move or take any actions
• Don’t count toward the Gang Up bonus

Recovery: At the start of a Stunned character’s turn, he makes a Vigor roll as a free action. Success means he’s no longer Stunned but remains Vulnerable until the end of his next turn. With a raise, his Vulnerable state goes away at the end of this turn.
