Hi! I just completed my first deathworld marathon speedrun and it was the best worst base I've ever built

I followed similar rules to default settings, random seed (i. e. really, really good seed) and not using imported blueprints. I used save/reload trick to fight biters.

Time: 12h 56m 44s

I have to split the video in two because it is over 12h.
EDIT: game starts at 53:57
