I have an idea about that pic. In past games abe chanted and possesed the closes thing to him but in the new 3d games he chants and gets a possesion orb which he can move around, the more spooce he has the bigger and stronger the orb. and in past games when abe turned into the shrykull he destroyed the closes things to him. Maybe on games to come abe will somehow turn into the Shrykull but he has a sort of destruction orb which he can move down unexplored hallways. its just a guess but that what it looks like in the picture.
