Vault: A Voice Escape Room. A concept. An experiment. A game. You are locked inside a glass vault. The walls are already moving. There are no buttons, no UI, only the Vault Guardian, a live ElevenLabs voice agent that protects the vault. Your voice is the key. It speaks a riddle. You answer out loud. Convince the Guardian you've earned it, and the vault shatters open. Fail, and the walls seal you in. Try it solo, or bring a friend in co-op. In co-op, the puzzle splits in two. Each player gets their own Guardian in a separate live conversation, each holding one word of the answer. Neither of you knows what the other was told. You have to piece it together, and solve both halves before the walls close on you both. Built on ElevenLabs Conversational AI for live, real-time voice agents. Cloudflare Durable Objects power the vault itself, a shared game server at the edge, owning the wall state, the timer, and keeping both players perfectly in sync. Your voice got you in. Now use it to get out. You have 100 seconds to live.
