Players identify victims by comparing numbered body records against manifests using clues like dental records, clothing, and surgical scars. LilyCompany says the game includes 17 types of supporting documents, such as in-flight sales receipts and hotel records. The interface allows players to organize evidence on a desk, arrange document cards, and use sticky notes.

Users can access tiered hints for every body record, benefit from auto-saves, and avoid strict time limits or penalties for incorrect conclusions. UNKNOWN PASSENGER 47 supports English, Japanese, Traditional Chinese, Simplified Chinese, and Korean. A Japanese-language browser demo is available online. Reports say the game has reached 60,000 page views and takes approximately two to three hours to complete. LilyCompany has not revealed the price or the release date.
