Before you start
This chapter lists 4 amber, 27 notes and 8 tapes (39 stops). Entries follow the published collection reference’s order, grouped into broad story stages. These groups are navigation aids, not a promise that every stop is immediately accessible or that no backtracking is needed. Follow your active objective and use the Chapter 3 walkthrough between detours.
Checks are shared with the amber, note and tape guides on this browser. Image reviewed means the linked source image was compared with the route; Community report means the final pickup remains unconfirmed here. Item names are reported labels. Seven notes remain unmapped across the game; this is not a complete 97-note achievement route. Toy deliveries remain in the separate pickup and pedestal list.
