Both the Core Rulebook and the Galactic Master’s Guide have been updated to resemble a Hazard Manual. I believe the new style helps keep the theme, whilst being easy to read.
As Under a Hostile Sun is not a combat-driven RPG, new GMs may be unsure how to plan a good session. The Galactic Master’s Guide is here to help with that! The Galactic Master’s Guide features nearly 80 pages of content that will help you design Hostile Sun stories.
Be sure to check it out, and furthermore continue to check out my short videos about the game on Rumble.
I am hoping to record a Playtest soon, showcasing the newest rules.
