Available project

AOS / The Continuity Index

An archival interface built around uncertainty.

AOS / The Continuity Index presents records, media fragments, internal communications, and restricted materials as part of a larger continuity-control system. It is less a traditional game and more an interactive dossier: slow-burn, atmospheric, and deliberately unresolved.
