Lotte Entertainment launched an O2O convergent AR campaign ahead of the release of Omniscient Reader's Viewpoint to allow the audience to experience the film's worldview in reality. Interacting with the character ‘Bihyung’ at subway stations, users were required to complete four immersive survival missions:

1. Dongho Bridge Mission: A timing-based action game where users cross a broken AR bridge within a time limit.

2. Chungmuro Station Mission: A control game navigating the character to safety zones (Green Zones) on a 4x4 grid.

3. Viral Mission: A sharing mission designed to spread movie promotion.

4. Record of Fate Mission: A mission to watch the film's teaser video.

Driving organic viral spread solely through in-game missions without separate ad spending, the campaign attracted approximately 10,000 participants and recorded a play conversion rate exceeding 100%, drawing an explosive response from the fandom.
