Certitude was developed by a group of students in collaboration with a Library staff member and a freelancer. The team included
- game designer and writer Rebecca Kerr
- programmer Sishir Sharma who developed the prototype code
- artist Jesse Bryant
They are all students at Curtin University.
- Karen Miller's role as producer was to coordinate work, write the articles used in the game and advise on learning content
- Michael Wiebrands, a freelance Unity programmer, developed the final code
Funding was provided through the Higher Education Participation and Partnerships Program.
Certitude was inspired by popular narrative-based games such as Headliner, Papers Please, and Orwell, where players are tasked with assessing the quality and accuracy of information.
