Kill Lupercal and Space King

Warhammer 40K, and 40K adjacent?

Kill Lupercal

This short three episode series focuses on a titan crew as they deploy to defend Terra against the forces of chaos led by Horus Lupercal, once the most favored son of the Emperor of Mankind. While the "extras" don't have the best CGI the main characters and titans are well done, with nice action bits to accentuate the all too short story oozing in dark 40K goodness. Recommended especially for those who like Warhammer related stuff!

Space King

This animated youtube series follows a bunch of -space- psycho marines on their quest to find their missing god, the titular Space King, and is a hilarious take on the "totally not warhammer 40k" universe. Definitely for a more mature audience, and again if you like Warhammer 40K you might get a laugh from this. Go check it out, it's free on youtube!
