Hellblade: Senua’s Sacrifice was one example, with Pratchett pointing out the help provided by the Wellcome Trust’s Public Engagement Fund. The trust is a foundation in England that gives grants to projects in film, TV and video games that have a biological or neurological component. Part of the grant process also comes with support from consultants, who work with recipients. For Hellblade, that meant replicating Senua’s psychosis in a convincing and sensitive way, and so University of Cambridge’s Professor Paul Fletcher became integral to the game’s development.
