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 through 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.
As the match goes on, you draft upgrades — new weapons, passives, and talents. Play it safe with power now, or gamble on bigger picks later. No two matches build the same.
Your unit fights on its own; your spells do not. Meteors, freezes, poison clouds, and more — cast at the right moment, they turn a wave around.
Units aim and fire on their own — no twitch reflexes needed. Your calls are where to stand, when to cast, 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.
From tapping Join to taking a bow — the arc of every siege.
Open the panel on the stream, pick a class, and you are in — no install, no account, nothing to download. You play as yourself, under your own name.
Enemies march the path toward your base. Your unit attacks on its own — you choose where to stand, when to relocate, and when to spend your mana on spells.
Between waves, upgrades unlock. Grab a stat boost, take a weapon or talent that bends your class in a new direction, or Empower — sacrifice power now for bigger picks later.
Your team charges a shared Siege meter as it fights. Trigger it to send a souped-up champion crashing into the rival stream’s defenses — with your name on it.
It all ends at the Rock Golem — a boss both teams fight at once. Break it apart faster than the other community and the pressure lands on them. First base to fall loses.
Every match ends with awards — top damage, clutch saves, siege mastery, and more — plus a full leaderboard so your chat can argue about who really carried.
Pick your class when you join, then shape it with the upgrades you draft. Mix your team’s roles to counter what’s coming.
