Wow. Awesome as always.
It's a testament to the animator's skill that after two shorts worth of the Marines just curb-stomping everything they encountered, you still manage to feel invested and like the marines are on the ropes once they encounter those... those weirdoes? High class psykers? Sans? Whatever you want to call them and/or they are. Their designs are so intricate and, like, distinctive that I can't help but feel they're some kind of GW property, but I can't imagine which creatures they are.
