Gumshoe is an adventure game that was in development by Hiding Buffalo in 2002 / 2003 for the PC and the original XBOX. As we can read in the original press release:
The concept for the game along with a working prototype were created as Hiding Buffalo’s entry in the 2002 Dare to be Digital competition, which challenges groups of students to create a new and original piece of digital content. Entries are judged by a panel of industry experts on their originality and commercial potential. Gumshoe was chosen by a majority of the judges thanks to it’s unusual concept, naturalistic dialogue system and innovative gameplay and episodic approach.
In the end, they never found a publisher interested in the project and so Gumshoe was cancelled. It’s interesting to notice that Hiding Buffalo did released a flash version of the game in 2006, even if it looked much different from the PC and Xbox version.
