The world through Iris’s eyes.
The harbor has gone quiet, but Iris is still on shift. One broken relay chain stands between the repair crew and the last train home. You are the familiar voice in her earpiece, helping her think through the route.
Read the notice before starting the Service console. The clock begins with that first deliberate action. A wrong relay resets the chain, so clear directions matter more than speed. Jules is waiting by the square with a little encouragement and no intention of leaving Iris behind.

A modern 3D city at night with original relay terminals, a radio engineer named Iris and a timed repair puzzle. Use custom game rules, counters, retry logic and a special ending. Keep Atlas outside the game.
