TTG: Will the hero interact in conversations with NPC and even acquire their help for brief periods like we have seen in some FPS like the Halflife series, or will he be doing all the slaughtering himself?

BE: There will be Non Playing Characters in the game - if you can find any still breathing - who may be of some assistance to you, but not in the way that they will be beside you in a fight. But, and it's a big but, your character can have some help from another character during the action sequences. Because this is an integral part of the game, the only thing I'll say about this is that your character isn't what one would imagine a 'man of the cloth' to be. Not only is he good with a gun, a knife, a sword, etc. there is something about him that could come as a bit of a surprise.
