Meh....
Aside from the normalmapping (which I have yet to see), the engine my team is working can do just as much and seemingly more. Distortions, bloom, heat waves, etc. And IMO the art direction in these screenshots isn't very good.
1500 smiths in a scene? I'll believe it when I see it. I wouldn't be surprised if they just turn out to be sprites, or render-to-textures.
