If you haven’t been keeping up with your Warhammer 40K fan films, Astartes first premiered roughly two years ago. This story tells the tale of the Argosa Uprisings, an anti-Imperium rebellion that was tearing apart a world. The Emperor ain’t got time for that, so he sent in the Space Marines to clean things up.
The first few parts show a squad of Space Marines deploying from their ship, breaching an enemy craft, and cutting their way through the opposition with ease. Part 4 showed us an epic battle between the Space Marines and two powerful psykers which has a flashy conclusion, leaving the remaining Space Marines staring at a sealed door.
The mystery of what’s behind that door will be answered today — you can watch the Astartes Part 5 premiere at 5:00 PM Eastern. Until then, you can catch up with what’s happened so far in this handy YouTube playlist.
