Cassidy is set in modern times where you're taken to a Manor that has gone through a horrific event in the 1950's. Playing in a first-person perspective as a crime and investigative student, it's your job to find out as much information as you can about what happened... and to try to get out alive.

Playing as a crime and investigative student, you're writing a thesis for your studies on the famous manor that's home to the gruesome murders that happened in the 1950s. Originally, the manor belonged to a friendly enough Grandma, whose husband died, and people started to see her less and less. They started to hear noises, and see strange red lights coming from it. Whenever someone went to check, the Grandma was nowhere to be seen, and the manor was empty. Eventually, a new family moved in, only to be the victims of a gruesome murder where the young daughter, Cassidy, was believed to have witnessed it all.
