About

Underline

Features
Read full description

Underline is a metro builder set in real cities. Pick a city and draw lines across it. Every station you place sits somewhere real, and the passengers who use it are where people actually live and work — the map is built from real population and employment data, so demand isn't invented. Put a station where nobody is, and nobody rides. Choose how each stretch gets built. Tunnel under expensive ground, run elevated, or stay on the surface where there is room. Set how often trains run and how long they are, then watch people find their way across your network — and watch the crowding when you have got it wrong. • 35 cities across five continents, from London to Tokyo to São Paulo • Demand modelled from real population and employment data • Tunnel, elevated and surface track, each with its own cost • Ridership, crowding, revenue and running costs tracked day by day • 110 commissions to complete, from straightforward to genuinely hard • No account, no ads, no tracking, and it works entirely offline • Interface in nineteen languages Five cities — one on each continent — are free, along with fifty of the commissions. A single payment unlocks every other city, the commissions set in them, and unlimited budget if you would rather just build.
