From the developer:
Murder Mystery Machine is a new kind of detective game that challenges you to piece evidence together and deduce the story of the crime. It is an immersive interactive detective game which will challenge your deductive abilities through unique mind-map puzzles.
Fresh-faced rookie, Cassandra Clarke, is teamed with a reluctant burnt-out detective, Nate Huston, to investigate the murder of a prominent politician.
