I've never played Warhammer 40k and don't really understand anything about what it is or how it works but I saw this a while back and was blown away. It's hard to believe a single person made this. I don't know how accurate it is to the story or lore or whatever 40k is but for one person to design all of it is incredible. Even just the sound alone is amazing.
It's incredible isn't it? I can't believe that only one person made the whole thing.
In terms of the lore - the "bad guys" (the spheres) in this are something that is scarcely referred to in any of the lore over the years. Essentially there is very little known about them. So I believe that the creater was able to take some liberties.
I also don't know anything really about the two psychers that were guarding the vault, nor do I know anything about that giant statue thing.
I really hope he is able to expand on this series.
The Marines were spot on, the traitor/corrupted Guardsmen were spot on. The member of the inquisition that tried to penetrate/link into into one of the spheres was spot on. The Captain putting his fist through the member of the inquisition's head as soon as he realised he was corrupted, and his offsider finishing the job - with pure disdain - was spot on.
