428 uses a Time Chart to interconnect character stories. Choose the numbered option at each listed time and use Jumps to unblock Keep Out events. These instructions concentrate on the verified route selections and ending requirements in the Steam version; some intermediate Time Chart transitions are left to the in-game prompts. Keep a save at the beginning of each hour.
Option A/B/C refers to the onscreen choice order; Jump means follow a red highlighted character link rather than simply selecting the other character from the chart.
