Adam F tries not to suck at Chaos Gate 40K WH, part 3

This is on hard difficulty, Grand Master mode enabled so I cannot reload any missions. Any mistakes I make are permanent no matter how catastrophic. I will attempt to beat the entire game, or go as far as I can until I get a game over. This takes place after a few missions after part one that I did not record. I go on a red level difficulty mission to destroy some seed carriers. Most of the mission goes well, then everything kind of goes horribly wrong toward the end and I barely survive it.

I am also a published author, and if you're interested in checking my novels out, here is the link to my website: https://www.adamfreestone.com/ They are also available on Amazon, and here are the links if you would rather look at them there.
