Our take on Sethian

The game’s focus on learning one invented language gives its mystery a distinctive structure, but it also makes progress depend on sustained study of grammar, vocabulary, and references rather than varied puzzle types or action.

What is Sethian?

Sethian is a science-fiction puzzle game set on a distant planet where an archaeologist investigates the disappearance of its people.

An abandoned computer contains possible answers but communicates only in the lost native language. Progress depends on learning Sethianese through its grammar and vocabulary, then using that knowledge to interpret the computer’s messages, literature, lore, and philosophical ideas. A handwritten journal and dictionary provide more than 100 pages of reference material during the investigation. The language draws on elements from Chinese, American Sign Language, and other real-world languages while adding invented features. Understanding the language leads to multiple endings, with the fullest conclusion requiring knowledge of the wider world as well as the language itself.

02Reference Journal

03Multiple Endings
