Apparently, there are to be three follow-ups in total so far, including Lust;
“As for the next immersive theater production itself, Bousman and Sears are clearly hoping to keep Lust under wraps for as long as possible, but they do admit a few things. The show will feature an ARG component to set the stage (though Bousman adds cryptically that the “fantasy universe that exists within our own will be much bigger now,” and that the ARG could extend to cities beyond Los Angeles). And while he won’t go into specifics, the director acknowledges that Lust — as well as additional planned follow-ups like Nefarious and Adrenaline — does take place inside the same general universe.”
