Hi !! Can someone help me finding new positive and negative features?during the first sessions we have some difficulties !

and, how do you use the Zombies/Infected Features? only narratively or adding positive and negative dice? example, The infected Prime have Unnatural Athleticism + , i'll add 1 or 2 positive dice in Athletics rolls, but, with Horrifying+ or Feels No Pain+ ?

Thanks

You only add one die for each "+". So Unnatural Athleticism would grant the zombie one additional positive die on athletic type rolls.

Feels no Pain could add a positive die to any vitality rolls the zombie makes.

Horrifying could add a positive die to the zombie's rolls if it's making an opposed roll against a player character or a human npc. See page 20 for opposed rolls.

Hope this helps.
