Yes, but I think it's a bug. I can't remember which encounter it happened in, but some animal I fought (either a boar or a lion) was not taking any damage from my fighter's greatsword (slashing damage) The combat log kept saying BB_Fighter grazes Boar for .8 damage. then 2 damage, then 00.00 damage etc), but on the other hand, my mage ( my MAGE!) was nailing this animal for 50-60 damage with his rifle.
That gave me a chuckle
Don't forget zombies. I believe in one of the preview videos there were a bunch of shambling humanoid corpse looking things. I would assume that would also mean there will be things like mummies etc
