Epilogue

Interact with 'Systems, Administration & Maintenance Online' to begin the final sequence.

Wait through the extended sequence, pressing 'A' at certain points for optional dialogue.

Prepare for the final call-and-response.

For the first set, input: Infinity symbol, cube with three branches, then three cubes pointing to one (X, Right, Y).

For the second set, input: Eye, box pyramid, then a square and a circle on opposite sides of a shape in the middle (Down, B, A).

For the last set, input: Line of three shapes, arrows pointing to the right, then something looking like an old radio box with three squares in a line (A, Left, Up).

Watch the final cutscene (a non-interactive cinematic the game plays automatically) (a non-interactive scene that advances the story) to beat Observation.
