Welcome to District Null

District Null is a city builder that runs in your browser. The Colonial Authority sends you to planet AZ884, right into its toxic north. You get a patch of land by the highway, a little starting cash and one job: build a city out of nothing. From now on you are a District Lord.

What the game is about

• Plan your city: lay roads and zone open districts, dense districts and industry. The city raises the buildings on its own once location, power and demand are right.
• Build up industry: dig pig iron out of the cliff, smelt metal in the blast furnace, later mine kryptonite and spice and forge high-grade alloys.
• Distribute power: without a power plant hardly anyone moves in and no mine works.
• Keep people safe: police, fire department and hospital keep crime, fires and disease under control.
• Grow: unlock new districts, open up the upper level on the plateau, research and build major projects.

Your city keeps running

The economy runs in game hours. Taxes, wages, mining and construction keep going even when you are not watching. If you are offline, everything keeps running. How fast a game hour passes depends on your city's speed.
