It does indeed look very pretty, with lots of particles swirling around in a way that's reminiscent of the Unreal Engine 4.0 trailer that we saw last year. The differences are noticeable too, especially in the segment with the red armored individual that has giant thighs. And by giant, I mean giant.
The effects are a little odd in places though. They look great and are very impressive, but I don't know what they're supposed to be. The fire stops looking so much like fire and looks more like fairy dust.
