Coffee Noir is an experimental combination of a detective novel and a business management game with elegant 2D graphics in a comic-book style spiced up with jazz music and retrofuturistic feeling. It offers clever and challenging entertainment, with an advanced economic engine designed by academics and equipped with actual market functions giving a complex business simulation.

At first, Coffee Noir was designed as a serious game for educational purposes. Thanks to a lot of positive feedback from gamers and several prizes received at video game fairs, we decided to expand our idea. Improved graphics, professional voice-overs, more comic-style cutscenes, extended storyline, detective-style game events and point-n-click mini games - all for a true gaming experience focused on intelligent entertainment.


In an alternative future, the world of 2021 Neo-London is ruled by coffee. Player discovers the story as Arthur Oliver, a hard-boiled detective who unexpectedly becomes a part of Neo-London's dreadful puzzle and must find out why Richard Kersey - a local coffee market businessman - disappeared without a trace. He has to work undercover as a coffee salesman to gain the trust of the industry’s tycoons who might have the information that will help solve the case. The investigation won't be easy, as everything and everyone on the path seems to be entangled in it, even the past...
