Profession Investigator is a game that takes you on a journey to the 60s, where you get to immerse yourself in the world of an investigator and solve several tragic cases. The game focuses on the investigator's work with documents, where a head and a fountain pen are the weapons of choice. The game mechanics involve reading case documents and transferring important information to your notebook, managing the work of the investigation team, and appointing expert examinations.

One of the most notable features of Profession Investigator is that it is based on real criminal cases. The game uses realistic terminology and descriptions in the documents, which are based on court archives, expert opinions, and specialized literature. The developer has also hired former investigators as consultants to provide an authentic experience.
