Back 4 Blood Extension Launch Directions

Updated: Nov 9


Check out our instructions to add the Back 4 Blood stream director extension to add features to your stream!


What Does the Muxy Back 4 Blood Extension Allow you to Do?

Patch Update (11/9/2021): The extension now allows viewers to use bits to name a random Ridden their Twitch channel name. When you kill that Ridden, their name appears in the Kill Feed in the upper-right of your stream. You can enable or disable the “Name a Ridden” feature in the extension’s configuration page.


The Back 4 Blood Beta Extension allows viewers to look through a broadcaster's currently active corruption and player cards. Clicking on a card thumbnail will display a larger version of the card and description text. When enabled, viewers can vote on which player cards to pick from the draw at each checkpoint and the card with the most votes will be added to the in-game deck. This addition affects the rest of the ongoing gameplay in the broadcast session.







Extension Install And Configuration


Broadcasters can install the extension on their Twitch channels and test from there. Here is the link to the current version of the extension: https://dashboard.twitch.tv/extensions/zy791s66p9q7khgpeygb528zi85bh9


While logged in to Twitch visit the extension URL above and click on the ‘Install’ button.


Once the extension is installed, you will need to activate the extension by going to the My Extensions list and setting the extension as active. This will move the extension to the Activated column and viewers will see it when you broadcast on Twitch.

Paste/Enter your PIN from the extension configuration page into the text field.


Confirm that you have successfully paired. If you have paired, you will see the option to ‘Deauthenticate’ which would unpair. If your attempt was not successful, refresh the extension configuration page to get a fresh PIN and try again.

Once you’ve got the extension active and have successfully paired with the game client, you should be all set. Now the extension can display your card info and conduct votes for card draws.


Once the extension is paired, you can enable or disable the Name a Ridden feature on the extension’s Configuration page. All you need to do is toggle it off or on. The drop down allows you to set the amount of Bits a viewer needs to use to rename a Ridden.


IMPORTANT: You will need to edit your stream info on the Twitch Creator Dashboard page to set your Category to ‘Back 4 Blood’ for the extension to remain active. Changing your stream info to a different category will de-activate the extension automatically until you set your category to Back 4 Blood again causing the extension to activate itself again.


Extension Functionality


Name a Ridden

The extension now allows viewers to use bits to name a random Ridden their Twitch channel name. When you kill that Ridden, their name appears in the Kill Feed in the upper-right of your stream. You can enable or disable the “Name a Ridden” feature in the extension’s configuration page.


Card Info

As you progress through a game, you will accumulate a set of cards relevant to the map or round that you are about to play. The extension will allow viewers to see the active cards and read their descriptions.



Card Draws

At the start of each campaign level and during the pre-round phase for Cleaners in PvP (Swarm mode), the game will present a selection of 5 cards to choose from for your character. If you’d like your viewership to pick your card for you then you can hit the ‘Start Poll’ button that appears in-game below the card draw interface.



This will replicate the card selection in the extension and allow users to click on and vote on the card they want. During the poll as viewer votes come in you will see the incoming vote %'s for each card option. When you’re ready to end the poll, hit the 'End Poll” button in-game and this will auto-select the card your viewers voted for the most.



This is a clip from EdEMonster's Twitch stream when he discovers how to start the viewer poll. Notice how the percentage vote count changes under the cards as viewers vote!
