The Petroglyph ending is hilarious to watch. I think you were just about spot on for the story. Corrupted people corrupt the town and others, and things fall apart as they disappear one by one. Everyone black mailing each other while Max is free to capture the townsfolk and perform his plans. Shivers I and II were some of my favorite games playing growing up, and I had an awesome time watching you play and go through the adventure.
