Multiple Actions
Your character has to act fast. Can he do two things at once? That remains to be seen, but he can certainly try. Lets say your character needs to dodge around a corner while shooting at the Werewolf in pursuit of him — two actions, one turn. Both actions suffer from the attempt to perform them simultaneously.
In order to attempt multiple actions, announce all the things you want your character to do (during initiative) and the order in which you will roll them. Your character can attempt as many feats as you want him to try, though the more he divides his attention, the less chance he has of succeeding at any of them. Use an appropriate dice pool for this first action. From it, however, remove a number of dice equal to the total number of actions you want your character to attempt this turn (two dice if he's trying two actions, three if he's attempting three actions). Then, roll the first attempted action from the reduced dice pool.
Once you have determined the outcome of the first action, prepare to roll the second. Take the appropriate dice pool, remove a number of dice equal to the number of actions attempted, as before, but also remove one more die. For each consecutive action after the second, continue to remove an additional die, cumulatively, from the pool. Thus, the third action loses two extra dice; the fourth action loses three extra dice, and so on. If your dice pool is reduced to zero, you cannot attempt that action.
Multiple Opponents
When fighting multiple opponents, your character suffers attack and defense difficulties of +1, cumulative for each opponent after the first, to a max of +4.
