Metro Sofia

A calm, finite incremental game about the Sofia metro. You start in 1998 with three stations at Serdika and a single train. Ring the bell, carry riders, and dig the real line outward one station at a time - Vardar, Lyulin, Slivnitsa, then Mladost, the second diameter, the airport and Business Park branches, the third diameter and the 2026 extension to Levski. Every station is a real place, with its real name, its opening year and a fact worth knowing. The city sits under a dark veil and lights up wherever your trains reach. Each era opens with its own card, drawn from your own network. Finish the plan, then keep going - the districts Sofia never reached are waiting.

• Fleet, timetables, signalling, depots and a council of decisions bought with trust
• 117 achievements, hidden curiosities on the map and a golden train to catch
• A real ending ("Sofia took 28 years. You took...") you can save as an image, then a sandbox with seven commissions
• Offline progress, autosave, three save slots, save export and import
• Interface size and text contrast settings
