Gutherman Project was the working title of Toy Commander, a Dreamcast action game developed by No Clichè and published by Sega, released in North America on September 1999.
Several magazines and online publications mentioned Gutherman as one of the launching titles (along with Agartha) for the Dreamcast. According to futuregamez.net:
No Cliché have released some details about 2 Dreamcast projects on their site. Firstly, they have an action game called Gutherman where “aim of the game is to drive vehicles through several breathtaking missions“. The second title is an horror-adventure game called Agartha which apparently will use “a new innovative character control”. Both titles will be launched with the Dreamcast in August.
The magazine Computer And Videogames (issue 212) mentioned (with the title Gutherman: Toy Commander) “some kind of Mario-style kids platforming game“:
