Marines from h1. Lol. of course im just joking, but i always thought it was funny how if you ever made them mad at you they wouldnt stop trying to kill you for the rest of the campaign. Lol. You think legendarys hard, try pissing the marines off and then see if you can beat it on legendary🤣🤣🤣. aint gunna happen. but tbh the funnyest legitimate enimey would have to be promethian crawlers. I like the noise they make when you shoot them.
