Player guide

What you need to know to take a call and decide what leaves the station. It explains how each piece works; what to send to a given call is something you find out by asking, which is what the game is about.

• The map reads by shape and colourWhat every diamond, disc and shield means, what the grey question mark stands for, and how to tell at a glance whether a call is ringing, confirmed or has grown.
• Every call has a problem of its ownThe twenty types that can ring, with what each one is and what sets it apart from the rest. What any of them needs is found out by asking, not by reading.
• The fleet opens up by station levelThe seven vehicles that can be owned, with what each one costs, how many people it carries, how fast it travels and the station level it becomes available at.
• Research is paid for with three currenciesThe eight branches and their twenty-one advances, with what each one asks for: money, real hours and accumulated experience of the matching kind.
