You run to the bunker and hope you don’t die before you get there. Then you do it again every day for a year. It’s scary enough that you never stop thinking about it even 20 years later.
Well I finished up Honor mode a few days later than I thought. But I did find out that sending Gale up the stem at the end does skip the final fight and still rewards the golden dice. Good luck!
I’m going to assume yes only because it worked for my tactician trophy. I will update you by the end of the week as I plan on having my run done by then.
