When it is about ghost, we surely expect jump scare would be the main element of the game but, Ghost Theory is offering something different. Ghosts will not jump around for no reason, even most of them won't be responding to our presence. But if you want to complete your objectives, you need to make them respond to you and you need to figure out how.
Ghost Theory was under development with Unity3D but since the developers think it is not the right engine for the game, they switched to CRYENGINE.
Here are some screenshots for Ghost Theory.
Ghost Theory scheduled to be released in Q4/2017 for PC, PlayStation 4 and Xbox One.
