This special edition includes reworked versions of the three games in the series:
Casebook: Episode I - Kidnapped
Casebook: Episode II - The Watcher
Casebook: Episode III - Snake in the Grass
The games have been enhanced with new mini-games, a new evidence linking system, a hint system and a ranking system in which you work your way up from a Lab Technician to Forensic Expert. Statistics show how much of the available evidence you have found, divided into two categories: Hard Evidence which is essential to the case and Other Evidence which is optional. The mini-games can be skipped, but doing so lowers the final score, as does using the hints system.
