[Spoilers] Black Mesa's Nihilanth, but with Mick Gordon
Now the ultimate question is: Is this Black Mesa, with Mick Gordon in the background, or Mick Gordon, with Black Mesa in the background?
Joel Nielsen's music for all of Black Mesa as well as this fight is really epic and very thematically appropriate for Half-Life's sciencey feel; but this still felt like a fun thing to do.
