We never got to find out what happened after Gone Missing, or what the outcome would have been if we had chosen differently. Why not make a new campaign based on it?
You'd play as Leslie with your NPC partner Keith investigating the three missing kids and all that. The story would be the same as the original but in a playable form where you can choose where to go in Raven Brooks, and there would be many outcomes. Then we'd also get to find out what the hell happened after the cliffhanger, maybe Quentin should come in as a character in the campaign siding with Leslie after the initial ending we got to Gone Missing.
