Play as Cambridge, Massachusetts
Cambridge is a sovereign city-nation of Massachusetts — universities, biotech, historic Atlantic ports. Massachusetts sits above it as the federation head, the Crown of the bloc, the way Washington DC once stood over America. Cambridge runs its own treasury, its own resources, and it offers citizenship to anyone who asks. Claim it, found your nation, and your capital lands on the real coordinates of Cambridge.
Cambridge is offering citizenship
Open borders. Anyone can apply, no reputation check, no invitation needed. City-nations carry 50% more money and resources than an ordinary state, and they share what they hold with their citizens.

Massachusetts doesn't compete with its cities — it presides over them as the federation head, the seat of the bloc, the way Washington DC once stood over America. It sets the bloc budget, fields the federal army (101,274 soldiers, 3,658 tanks) and holds a balanced posture. If you go to war, you can pay the Crown in SFC dollars to fight alongside you, provided it's backing three or fewer wars at that moment.

Questions about Cambridge
Why claim Cambridge instead of another state?
Location shapes trade proximity, who sees your mobilisations, and which coalition armies are cheap to reach. Cambridge puts you in Massachusetts's wider interior, which is a different opening than the capital.
Is playing from Cambridge free?
Yes, entirely. No download, no paywall, no premium tier — Cambridge plays in your browser on desktop or phone.
Can two players claim Cambridge?
Each player anchors their own nation, and multiple nations can trace their origin to Cambridge. What separates you is what you build — population, treasury, technology and army.
Which states border Cambridge?
Inside Massachusetts you'll be neighbours with Lowell, New Bedford and Springfield. Any of them can be claimed by another real player, so the state you pick decides who's next door.
What do I do first after claiming Cambridge?
Set your tax rate, collect your first day's revenue, pick a government, and build infrastructure before you buy soldiers. Military upkeep sinks new nations faster than any enemy does.
