About this game
A Colonial Noir Mystery
The Red Pearls of Borneo is an atmospheric deduction game inspired by Return of the Obra Dinn, The Case of the Golden Idol and Type Help. You are a clairvoyant investigator in 1948 London, exploring the psychic echoes of a tragedy that occurred seven years prior on a remote plantation in Borneo.
Your tools are simple: a box of old photographs, a map of the plantation and your unique ability to step into the past.
London, 1948
Jeremiah Goodwill's tobacco plantation was supposed to be a paradise. But on the night of December 16th, 1941, as the Japanese Imperial Navy loomed on the horizon, the estate fell into chaos.
Sort through the lies. Reveal the faces of the strangers. Discover what truly happened in the Goodwill plantation that fateful night.
Key Features:
Echoes of the Past: Explore a non-linear timeline. Jump between witness perspectives and moments in time to uncover motives, secret meetings and fatal mistakes.
The "Mind's Eye": Use a unique node-based deduction system to visualise the movement of guests across the island. Connect the dots to prove who was where, and when.
Make notes of everything everywhere: You can keep notes on all aspects of the game. From characters and locations to items and snippets of text from clues.
Learn about the rarely told history of Borneo on the eve of WW2 through the interactive glossary you will unlock as you go.
Can you piece together the truth before the memories fade? Identify the guests, determine their fates and solve the mystery of the Red Pearls!

"Green Mist over Portland" Surpasses 20,000 Wishlists!
Dear Investigators, Thank you so much for your incredible support—we couldn't have made it this far without you! "Green Mist over Portland" has officially surpassed 20,000 wishlists on Steam, and we are hoping to reach even more players! Have you had a chance to play our demo yet? Over the past few days, we've rolled out several updates based on your feedback and are continuously working to optimize the game and fix any issues. We hope you can see the effort we are putting in! https://store.steampowered.com/app/4644870/_/ Today, we have updated the game with a special bonus reward. If you have collected all available content in the demo (players who have already finished the demo can simply hit "Continue" to access it), a brand new "Next Morning" button will appear at the end. Clicking it will reveal special dialogue and unique story hints, giving you an early sneak peek into the plot of the full game. {STEAM_CLAN_IMAGE}/46018674/2463ce6ff383c295408636cc887963421e746a9f.png Please keep in mind that this is still just a demo, and the real story has yet to fully unfold. If you are coming straight from the ending of "The Red Pearls of Borneo", we ask for your patience—the limited scope of a demo simply cannot deliver a fully complete narrative just yet. "Green Mist over Portland" is expected to feature a story twice the size of "The Red Pearls of Borneo", along with more engaging puzzles (we are working hard to make sure they are genuinely fun!). Unlike "The Red Pearls of Borneo", "Green Mist over Portland" will introduce a new stage and a new tone. However, it will absolutely retain the same delicate atmosphere, in-depth character development, and rich narrative. We know exactly what you expect from us, and that is exactly what we are focusing on. Wishing you all the best!Read full article on Community Announcements (Surefire.Games)AnnouncementsOfficial
