Warhammer 40K Boltgun DLC - Mission 5 - 100% All Secrets - Daemonic Forge - Exterminatus No Grav gun

This is the second version of my no-death playthrough of Warhammer 40K: Boltgun DLC Mission 5 , "The Daemonic Forge", on Exterminatus difficulty. The video also includes the ending cut scene, ending credits, and a post-credits scene.
All 11 secrets were found. Also, I did not use the Grav-Cannon weapon.
I could have beaten this mission quicker than 9 minutes, but I decided to finish the final enemy with my chainsword, so had to spend extra time getting setup for that event.
Note that when I started this mission, I already had a Vortex Grenade equipped that I did not use from the previous mission, which was carried over in my saved game.
