Ok I love the new Imp design, the Pinky and the Baron at the end. Notice they also have colour (gasp!) on them.

It's almost as if someone sat down and played the original Doom, sometime after all those boring, samey, greyscale, eyeless bellend-head monsters were made, and said "haaaang on....why don't we just make monsters with eyes and personality and that actually look different from each other, kinda like in the original game?"

I hope that guy got a raise.
