The MetaMovie Presents: Alien Rescue is one of the most immersive experiences I've had in VR. It's part Cinematic Adventure, part Immersive Theater, and part game that's fusing the affordances of each of these different mediums in a unique way. There's one interactor who is cast as the protagonist who meets up with three other immersive theater actors who are taking you on a fairly linear adventure to rescue some aliens. The main character gets to do some live-action role playing, customize their character's identity and expertise, and make a number of different choices along the way to potentially go down some forks in the story. There's also a number of other audience members there who are cast as iBots, which don't have as much narrative agency as they can't really speak, but they have more embodied & locomotion agency in terms of being able to explore around the environment as well as chose which characters and storylines to follow as the part splits up at different points.
