To experience the enigmatic UFO conclusion, players must adhere to a precise chain of hidden actions. Below is the revised methodology for activating this alternative narrative outcome.

Initiating Prerequisites

Commence by engaging with every accessible Radio Transmission during gameplay. While some playthroughs may only demand interacting with the initial broadcast, others necessitate activating all transmissions. Subsequently, discover and examine three concealed Advertisements in strict chronological succession to advance toward this finale.

Configuring Repeat Playthroughs

A completed standard playthrough is mandatory. Preserve your endgame data, then initiate a New Game+ session from the main menu. While difficulty selection remains flexible, the Lost in Fog setting remains viable. This mode unlocks restricted zones required for the secret ending sequence.

Radio Transmission Activation

Within New Game+, journey to the specified event zone marked by unusual lighting. Navigate using your map until protagonist Hinako initiates an automated crouching motion. This triggers the essential transmission requiring careful auditory attention.

Advertisement Sequence Solution

Post-transmission, locate three cryptic advertisements in this exact sequence:

Initial Advertisement

While approaching the Rice Fields residence, dismantle environmental barriers blocking progression. Investigate the vicinity surrounding the dwelling to discover the inaugural poster installation.

Secondary Advertisement

Following the Otherworld confrontation with Sakuko, progress until reaching the school environment after roadblock removal. The subsequent poster becomes accessible during pursuit sequences involving key NPCs.

Tertiary Advertisement

Locate the final poster in urban corridors post-secondary discovery. Navigate hostile alleyways, neutralize opposition, and interact with the terminal advertisement installation.

Final Sequence Execution

With all advertisements activated, revisit Central Thoroughfare. Engage or bypass hostiles before interacting with the extraterrestrial device positioned on a nearby surface. This interaction culminates in the activation of the alternative narrative resolution.

Meticulous adherence to this protocol—transmission monitoring, sequential advertisement interaction, and device activation—guarantees access to this unconventional conclusion.
