Play as Denver, Colorado
Denver is a sovereign city-nation of Colorado — Rocky Mountain spine, aerospace, energy, high plains. Colorado sits above it as the federation head, the Crown of the bloc, the way Washington DC once stood over America. Denver 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 Denver.
Denver 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.

Colorado 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 (120,049 soldiers, 4,434 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 Denver
Can two players claim Denver?
Each player anchors their own nation, and multiple nations can trace their origin to Denver. What separates you is what you build — population, treasury, technology and army.
Which states border Denver?
Inside Colorado you'll be neighbours with Grand Junction, Pueblo and Boulder. Any of them can be claimed by another real player, so the state you pick decides who's next door.
Is playing from Denver free?
Yes, entirely. No download, no paywall, no premium tier — Denver plays in your browser on desktop or phone.
Can Colorado help me in a war from Denver?
Yes, for SFC dollars. Colorado will join your side while it's backing 3 wars or fewer, which makes early declarations cheaper to support than late ones.
Who runs Colorado while I hold Denver?
The AI does. Colorado keeps its own treasury, army and war record no matter who claims Denver — you're a sovereign nation anchored inside it, not its government.
