    About the game

    Stream Siege is a tower defense played by the viewers of a Twitch stream. Every viewer opens a panel on the broadcaster's channel, picks one of six classes, and commands a single unit in a shared set of towers. The whole chat defends synchronized enemy waves together while racing a second stream (or an AI opponent) to defeat a boss.
