Cool stuff:
There was this one time in the demo where I did the stabbing finishing move against an orc, and then pushed that same orc against another orc, which stumbled back against one of those wooden pillars, broke it and proceeded to get pummeled by a bunch of barrels falling from the platform.
Another situation was where I used ice on the floor, an orc slipped on it and fell against some crates which I then set fire to thus burning the orc.
