I'm happy I completed Hardcore Campaign on a first try after proceeding to Prestige Level 1. It was very interesting challenge to start without weapons and tools straight on Hardcore.
This walkthrough is not excellent and smooth, there were some moments when I believed I'm going to fail. I decided to publish it because maybe it can help someone and give some ideas about how to start fresh on Prestige or how to complete Hardcore campaign.
This walkthrough was completed live on stream on May 13. For more live streams make sure to follow me on Twitch:
