Gameplay

Gnosia is a social deduction game akin to the likes of Mafia and Werewolf. **Gameplay** revolves around the human crew members attempting to discern who among them is the Gnosia and put them into cold sleep, while the Gnosia seek to eliminate all of the human crew members and take over the ship.

A given loop takes place across several days, with each day divided into two segments: the discussion phase and the night phase. During the discussion phase crew members discuss their theories and choose someone to enter cold sleep. During the night phase the player can move around the ship, speaking to characters to form alliances or confirm suspicions. The player can also level up based on experience gained in past loops, boosting their abilities and unlocking skills to help them control the flow of discussion in their favor.

Once the player has finished selecting a course of action for the night the crew members with roles will perform their night actions, such as the Gnosia choosing a crew member to eliminate. The game then proceeds to the next day and a new round of discussion ensues until either all of the Gnosia have been eliminated or the number of Gnosia outnumbers the number of humans. The loop will also automatically end of the player reaches Day 15 of a loop to prevent them from being softlocked by constant ties.

### Discussion Stats

Every character has a base opinion on all of the other characters, including the player. Some characters find other characters to be unlikable and will thus be more likely to jump on them or dismiss their opinions. Other characters, however, they might consider especially trustworthy and will be inclined to trust their judgment during debates. A character's opinions can change over the course of discussion, however, determined by three stats:

* **Amicability:** A measure of how liked the character is.
* **Trust:** A measure of whether one is considered friend or foe/human or Gnosia.
* **Hate:** A measure of how much negative attention someone's accrued. High hate makes one suspicious, but low hate can also draw suspicion out of an assumption that someone being quiet is trying to hide something.

Unlike abilities, these stats are completely invisible to the player and must be discerned through how characters act across loops.

## Roles

*See also: Roles*

There are 8 roles that the player and NPCs can be assigned as. A role typically grants a special night action, and some roles allow the character to lie and claim to be a role (Engineer or Doctor) that they aren't. A character who lies is capable of making a false report during the night phase, but runs the risk of their lies being detected by intuitive crew members.

* **Crew Member:** The default human role. Crew Members have no special night actions.
* **Gnosia:** The primary enemy role. The Gnosia can eliminate one human character each night. Gnosia are aware of fellow Gnosia. Capable of lying.
* **Engineer:** Humans who can choose one character per night to analyze and confirm as Gnosia or human. If they end up analyzing a Bug, the Bug will be eliminated.
* **Doctor:** Humans who analyze crew members put into cold sleep to determine they were in fact Gnosia or if they were actually human.
* **Guardian Angel:** A human capable of protecting one person per night. If the Gnosia attack that person, they will fail and no one will be eliminated that night. The protected character will not be made aware they were protected. Guardian Angels cannot declare their role, as it would make them an instant target.
* **Guard Duty:** Two humans who can vouch for the other being human. Gnosia cannot pretend to be on Guard Duty, so anyone declared Guard Duty is a definite human.
* **AC Follower:** An antagonistic human role that sides with the Gnosia. They can only win if they survive until the Gnosia take over the ship; even if the Gnosia would be guaranteed to succeed after the AC Follower's demise or placement into cold sleep the loop will still be considered a failure for the player. The Gnosia are not aware of the AC Follower's identity, making it a tricky role to win as. Capable of lying.
* **Bug:** A glitch in reality that will win and destroy the universe as long as they survive until the end, regardless of whether it's the humans or Gnosia that win. If an Engineer analyzes them at night they will be eliminated, but Gnosia will not be able to eliminate them. If there is no Engineer present, the only way to get rid of a Bug is to put them into cold sleep. Capable of lying.

## Abilities

*See also: Abilities*

Each character has different level of ability in various stats helpful for debate. NPC abilities will slowly increase across loops and will jump up with each Note unlocked. The player can customize their abilities in their room during the nighttime phase, with each level corresponding to one point to allocate. The player does not need to use all of their points and can freely lower points for their abilities if they wish to make the game more challenging.

* **Charisma:** Determines how inclined characters will be to trust and follow the speaker's opinion.
* **Intuition:** Determines how easily a character can detect lies from the antagonistic roles.
* **Logic:** Determines how effective a character is at having their statements damage or enhance another character's accumulated Trust. For the player, leveling Logic allows them to additionally view more lines in the text backlog.
* **Charm:** Determines the rate at which Trust and Amicability increase and decrease. High Charm makes a character more "likeable" and more likely to have others come to their defense and propose alliances.
* **Performance:** Determines how effective a character is at having their statements damage or enhance another character's Amicability. Performance also determines how good a character is at lying.
* **Stealth:** Determines the rate at which one's Hate increases and decreases and thus how much suspicion is placed on them. Characters with high stealth are less likely to be targeted by the Gnosia at night.

## Skills

*See also: Skills*

Skills are techniques characters can use in order to announce roles, cast suspicion on other crew members, deflect suspicions, bond with other characters, and otherwise control the flow of discussion. Some skills can be used freely, while others can only be used once per day or even once per loop.

There are 30 skills in the game, many of which must be unlocked by viewing special events at night and being taught them by NPCs. Some skills have required ability thresholds to use: for example, even after being taught the skills, the player must have 20 Logic in order to declare an NPC a Definite Human or Definite Enemy. Reaching the threshold for the first time will not make the skill permanently usable; if the player takes Logic below 20 points later on, they will no longer be able to use the aforementioned skills until they raise Logic to 20 or higher again.

## Setup and Event Search

The Setup option unlocks early in the game, allowing the player to customize loops to their liking. The player can control:

* The number of crew members.
* The number of Gnosia.
* If there is an Engineer.
* If there is a Doctor.
* If there is a Guardian Angel.
* If there are Guards.
* If there is an AC Follower.
* If there is a Bug.
* Which role the player will have.

The number of Gnosia allowed is limited by the number of crew members entered: the player cannot create a loop in which the humans automatically lose. If a certain role is not present, roles capable of lying cannot claim to be that role.

Upon obtaining Setsu's second note the player will unlock the Event Search function. Using Event Search will set the loop's parameters in such a way that the player will have the opportunity to obtain a Note they don't have yet. The player can adjust the parameters before officially starting the loop, though doing so may eliminate the possibility of obtaining the Note the game set them up to get. After all of the Notes have been gathered the Event Search function serves as a randomizer.
