What is confirmed
Read Gate Switchboard in the bar and Gate Fuses and Wires across the street. Linking those two clues in Investigation Space awards an optional talent point; the fuses themselves are collected in the Radio Store route.
What to do
At the floodgate panel, use the three fuse lengths as bridges so each same-colored wire completes a circuit. Follow the visible rails rather than forcing a memorized pattern, because the board clearly shows which endpoints must connect.
What is not confirmed
The clue link is optional, but the physical fuse repair is required. Claims about later campaign symbol puzzles remain preview information until the full game can be verified.
Player questions
How do I solve the floodgate fuse puzzle?
Collect the three fuses and place them as bridges between matching wire colors on the switchboard; link the two gate notes for an optional talent point.
