This film by Erasmus Brosdau is a labour of Warhammer 40K love. A few seconds into the short and you’ll see why its impressive. What we have is the first 8 minutes of a larger film called “The Lord Inquisitor”.
Frankly, I think that Inquisitor is a bit of a sadist.
This isn’t the first time we’ve been treated to a peak behind this made-in-spare-time animation. Back in 2014 Geek Native had another peak with a Grey Knight space marine suiting up.
