Social Deduction AI

Social Deduction AI is a university project that implements a simple artificial intelligence for a social deduction video game.

Overview

The aim of this project is to design and implement an AI agent in Unity that simulates the behaviour of a human player in a typical social deduction game.

In this case, more agents have to roam around the map gathering information, while one of them is a killer. If one of the agents find a dead body, a meeting starts, during which each agent share its relevant information, in order to identify a plausible suspect and vote it out.

If the innocent agents can spot the killer, they win, otherwise the killer will be the winner.

Structure

• Roaming phase: the agents roam around the map, while doing tasks and gathering information through their field of view. The killer can also kill one of the other agents.
• Meeting phase: the agents share their information to identify the killer, making simple logical inferences through a Rule-Based System.

For further information, see the project report.

How to Use

The project can be played either from inside the Unity Editor (Scene and Play tabs) or from a build.
