Nightfall is a free, browser-based social deduction game inspired by Mafia. Players are assigned secret roles and must figure out who's lying through live voice conversations, accusations, and voting. What makes Nightfall different is that AI characters can join as players, participate in discussions, answer questions, and make accusations alongside real people. You can create a private room, invite friends, or play with AI characters when you don't have enough people for a full game.

Could you build this?
Partial The Mafia game state machine is straightforward, but integrating conversational AI agents seamlessly into live multi-party WebRTC voice rooms is non-trivial.
What it would actually take: The stack needs a WebRTC SFU (such as LiveKit) paired with an ultra-low-latency voice pipeline (fast STT, conversational LLM turn-taking logic, and realistic streaming TTS). The critical bottleneck is conversational turn-taking, interrupting, and low-latency audio packet routing so AI players interact naturally in live group voice calls.
