The Murdoch Alternative Reality Society (MARS) is a club affiliated to the Murdoch University Guild of Students, dedicated to promoting alternative genre fiction (e.g., fantasy, science fiction, horror etc) and includes a very strong role playing and gaming stream (including an extensive library) along with other media.

The club was founded in early 1988, making it one of the oldest and most successful of its kind. It has its own website, message board and mailing lists. One is not required to be a student at Murdoch University to participate in the many activities this club arranges!
