A Twitch tower-defense your whole chat plays together.
Stream Siege is a multiplayer tower-defense game played live by the viewers of a Twitch stream. The streamer flips it on, everyone watching joins in and controls a unit, and the whole chat defends together against wave after wave of enemies. Two streams take on the same waves at the same time — racing to see whose community holds the line all the way to the final boss.
Every viewer joins right from a panel on the stream and controls one unit. No install, no account — just tap Join and you are in the fight.
Two communities face the exact same waves at the same time. Clear faster, survive longer, and pile the pressure onto the other team.
Units aim and fire on their own — no twitch reflexes needed. Your calls are where to stand, when to move, and what to upgrade next.
Clear nameplates, bold colors, and waves telegraphed ahead of time. A brand-new viewer can understand what is happening in seconds.
Everyone starts as an Archer, then spends shared gold to specialize. Mix your team’s roles to counter what’s coming.
