Adam F tries not to suck at Chaos Gate 40K WH, part 5

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 mission to have my 1st crack at destroying a Tent hive (I don't feel like looking at the correct spelling for the purple plague if you played the game). Unfortunately I don't really know what I'm getting into and make some critical mistakes right off the bat and I am defeated. I'm mostly just uploading this video in case there's something for other players to learn from my mistake.

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.
