Ooo. I hope that fat thing isn't a Fallen... Looks kind of like an Abomination. But the zoom and the graphics!
For all we know, both can be Fallen. 'Improved' humans and whatnot.
Anyway, saw the thread yesterday before it started spinning, but forgot to add; Great find! Can't wait for us to actually get a dev journal with some video footage.
Edit: Man, the base smiley is just plain creepy, staring like that.
