Feral Heart

If you found the horror stories narrated on youtube, you could set up a "Watch 2together" stream. Basically you set up a watch room and you have users log into your room and you choose a video that you will all watch. The link for it is here: watch2gether. That's one way you could possibly go about it, but users would have to keep the tab open, but they'd be in game and wouldn't have to switch back considering the audio is all they'd need. If I'm assuming correctly, you want the story to be in the map though? The only way I could think of that being possible is by converting the audio into an .mp3 and using it as the map's music, but after a while it would loop and you can't change it without releasing an edited version of the map each time, so it really wouldn't be streaming per say.
