Stream Siege turns your viewers into a team with a shared score to settle. That is retention you can feel: longer watch time, chat that talks to itself, and a reason to come back for the rematch.
Free for every channel. Nothing to download. A browser source in OBS, a one-click extension install, and your viewers are in the fight in about 30 seconds.
A match runs five to ten minutes and the next one starts on its own. Viewers stay for one more wave the way they stay for one more round, except they are the round. Nothing about it interrupts your own game or your talk segments.
Sixty viewers defending one base creates the kind of running stories chats are made of: the Bard who saved wave nine, the leaderboard rivalry, the draft argument. End-of-match awards hand your chat its own highlight reel every ten minutes.
Stream Siege keeps hosting matches as long as the source is live. Bathroom break, lunch, an away screen: your community keeps playing on your channel, and your stream keeps being worth watching while you are gone.
Viewers can unlock alternate class kits with Twitch Bits, and broadcasters earn a share of Bits spent on their channel. The kits are tuned to match the free ones in power, so nobody buys a win, and nobody has to spend to belong on the team.
The endgame is a race between two live communities on the same waves. Your chat against theirs, with the rival's base health ticking on your stream. Rivalries between channels are how communities cross-pollinate.
The board is drawn for the stream, not squeezed into it: bold nameplates, clear wave banners, a live contribution ranking. A first-time viewer understands the fight in seconds, and sees their own name the moment they join.
No downloads, no keys, no config files. If you have added an alert overlay to OBS, you have already done the hardest step.
Open the streamer portal, log in with Twitch, and your channel is provisioned on the spot: one click, no forms.
Copy your personal overlay link into OBS (or any streaming tool) as a browser source. That link is the game board, drawn live for your stream.
One-click install from the portal, pick a panel slot, done. Your viewers see Join the moment you go live, and the first match starts when the first one taps it.
The Stream Siege extension is in Twitch's review queue right now, which is the one step we cannot speed up. The moment it clears, this page becomes the portal link and installs open to every channel. Join the Discord and you will know within minutes.
Nothing. Stream Siege is free for every channel, with no tier, no trial, and no catch. Optional kit unlocks exist for viewers who want them, and during the beta even those are free.
The game runs on our servers, not your machine. Your OBS shows one browser source, the same weight as an alert overlay. There is nothing to install and nothing to update.
Just Twitch. The panel is a Twitch extension: they open your stream, tap Join, and they are playing. No account, no download, works on desktop and mobile Twitch.
No. Turn the browser source on when you want matches, hide it when you do not. Many streamers will run it as a segment; some will leave it up around the clock. Both work.
The team is filled to a playable minimum with computer-controlled allies, so a small lobby still gets a real match. Sixty humans can play at once when your chat shows up.
Stream versus stream matchmaking is part of the public rollout: two live channels race the same waves in real time. Until your first rival is found, your team races a tuned opponent so every match still has a race.
Players appear under their Twitch names, inside your channel, under your rules. Anyone you ban from chat is banned from your board.
