About this game
Build a city that lives on wires.
Arcwatt: Power Empire is a city builder where you design the power grid instead of roads and pipes. Housing, factories, commerce — everything lives while the current flows. And dies when it doesn't. Every tile is a decision.
Synergies: housing next to commerce — bonus. Factory smoke next to housing — penalty.
Overload: two supply lines into one building, and it burns.
Every building rotates. Every footprint matters.
Coverage is physics, not a magic circle
Radius is measured from the edge of the plant to the edge of the consumer. A generator wedged into the corner of a huge factory will reach. A panel two tiles away won't.
Where you build matters as much as what you build.
The city breathes with the sun
Solar panels are dead at night. Wind fades at dawn. Housing demand climbs in the evening. Plan for the dark hours — or sit in them.
The world hits back
Heat drives demand up. A storm cripples your turbines for half a day and strikes your buildings with lightning. Fuel contract: fast money now, slower income later. You have 20 seconds to decide.

ARCWATT: Power Empire is OUT NOW
ARCWATT: Power Empire has officially launched — and it happened live at Ukrainian Games Festival 2026. Thank you to everyone who wishlisted, playtested, filed bug reports and argued about generator placement. You built this launch with us. What ARCWATT is A city builder where the city is the easy part. Power is the game. Build the grid, not just the skyline. Every producer covers a real area measured from the edge of its footprint. Placement is the decision — not a formality.Demand moves. Homes spike in the evening, factories at midday, solar dies at night, wind wanders. A grid that holds at noon can black out at 20:00.Overload is real. Feed a building from too many lines and it burns instead of thriving — until you research your way out of it.Neighbourhoods matter. Housing lifts commerce. Labs crowd each other out. Factories poison the land around them — build homes there and the game says no.Things break. Storms cut renewables, heatwaves spike demand, generators fail outright. Repair Stations are not decoration.18 research nodes across five branches, including a Territory line that expands your buildable land from 100×100 to the full 285×285 map.One win condition worth chasing: keep the Megastructure powered for 72 straight in-game hours. No shortcuts.35 achievements, three difficulties, terraced terrain, day/night lighting, a full soundtrack that follows the clock, and quicksave.
