ChatBoss is a Twitch chat boss raid game where streamers and viewers team up in real time to defeat powerful bosses directly through chat. Viewers join a party, choose a class, type the words shown on screen to attack, charge ultimates, and coordinate with the streamer to survive the raid. The game is designed for livestream interaction, with party-based combat, class roles, streamer-led raid mechanics, Twitch chat commands, boss attacks, rankings, and short daily raid sessions.
