It was inevitable. Between the lush wilderness and vicious fauna, the world of Monster Hunter, uh, World is an ideal setting for some cryptozoological documentarianism. Or that is to say, it makes for great "BBC Planet Earth" type material.
One creative YouTuber put together a faux documentary treatment of the game, with the first episode being an up-close look at the creatures that inhabit the Ancient Forest. Said YouTuber couldn't get David Attenborough to narrate, so he does a reasonable impression of him instead.
We get the impression that there are more episodes to come in this send-up of Monster Hunter. And if that's the case then I'm definitely looking forward to the Rotten Vale episode. Let's see what "Attenborough" has to say about dem corpses.
