From the manufacturer:
Chronicles of Crime is a cooperative game of criminal investigation mixing board game, an app and a touch of Virtual Reality. You and your team will be put on crime cases, moving all around town, interviewing suspects or witnesses, and searching for clues in 3D scenes!
This game requires an app to work (it's impossible to play without it), but once downloaded no Internet connection is needed to play. You currently need Android 4.4 or newer, or iOS 8.0 or newer to run the app, which may change in the future.
