Both Metro's graphics are great. I haven't even gotten very far in 2033 yet. The Gas Mask broke in 2033 and won't let me remove it, though I read it can just be replaced if you find one laying around--but it's annoying running around with the huge cracked effect along the screen to look in the first place, so I've not played in a while.
Clearly a re-enactment from 300! That blokes about to start celebrating his kill, turn around to his father and then get his head sliced off. I would put money on it.
