About this game
Surface Doctrine: Crater is a niche role-playing game about the fates of three protagonists in a cruel and little-understood world whose very origin remains a mystery. Each hero sees this world in their own way, faces their own trials, and meets people whose reputation, faith, and sense of righteousness are rarely simple or unambiguous.
You will be able to play as any of the three protagonists. Their stories cross the same places, conflicts, and inhabitants of Crater, but each path reveals a different view of what is happening. Where one hero sees a threat, another may find an opportunity; where one is powerless, another may be able to change the course of events.
In Surface Doctrine: Crater, dialogue choices affect not only character relationships, but also the difficulty of what comes next. A careless word may close a path, strengthen enemies, cost you someone’s help, or make future scenes more dangerous. Attentiveness, cunning, compassion, or cruelty may instead open alternative solutions, new items, allies, or unexpected consequences.
Try to avoid conflict — or go looking for trouble. Buy equipment, brew tinctures, steal, uncover hidden stashes, bargain, interfere in other people’s lives, and speak with the inhabitants of Sa-Tae. The game includes mini-games tied to specific character actions: combat techniques, crafting, reading, alchemy, and other situations where success depends not only on stats, but also on the player’s input.
The world reacts to your actions. Some decisions change available scenes, character lines, prices, rewards, the danger of encounters, and the way people perceive your hero. Sometimes the consequences are immediate. Sometimes they return later — in another scene, another dialogue, or another route.
Behind caricature, foolishness, cruelty, or faith, there is almost always a less obvious human experience. Surface Doctrine: Crater is a game about righteousness and deceit, the causes of human actions, the cost of survival, and whether one can remain oneself in a world that refuses to explain its rules.

Hints Without Spoilers
The most authentic way to orient yourself in the game is to teach Vias to read and follow the notes in his journal. But if you get stuck, or are not sure what to do next, these hints may help.MorningAt his father’s request, Vias can take the found barrels to Ushasty by the gate, and to the leatherworker Kasab, whose house is also not far from the gate.You can follow your father’s instruction. Or, against his wishes, you can deal with the goods in another way — the choice is yours. In any case, you will need to report your decision to both Ushasty and Kasab.DayOnce day comes, the game invites you to get to know the people of the settlement. Some of them will ask for your help.But you do not have to speak to everyone — and doing so is not always wise. The settlement is not as safe as it may seem, and suspicious people are rarely suspicious for no reason. Sometimes it is better to walk past or return later.Your help may be needed by the carpenter near the broken house, the herbalist in his hut, the local drunk, and other characters. Their requests can be completed, ignored, or failed — the game will continue. However, to move forward, you will need to bring several matters to a clear conclusion.EveningEvening is the time for a deeper look into the history of the world. But you may see events from different sides, depending on what task is given to you by the person responsible for the settlement.During this evening, a single playthrough will let you learn more about the worldview of only one side of the conflict.NightAt night, your main task is to prepare for sleep. This stage is simpler than the others: by this point, the player should already be familiar with the basic principles of the game, so additional hints are hardly necessary here.ImportantQuest progression is not meant to be linear or require 100% completion. You may agree to help someone and still fail to help them — that is normal.In the demo, such situations introduce you to the logic of the game and to th...Read full article on Community Announcements (OHMY)AnnouncementsOfficial
