How it plays

One loop. Bigger every week.

  1. I

    Build houses

    People move in. They pay taxes in coins and count as your population. A hut pays a little every three minutes; a big house pays a lot once a day. Taxes wait for you and never expire.

  2. II

    Put the island to work

    Farms earn coins, lumber mills cut wood, oil wells pump oil and mines dig ore. Short orders while you play, long ones before you log off.

  3. III

    Raise an army

    Barracks train soldiers, artillery and tanks. Shipyards launch gunboats, carriers and battleships. Hangars put fighters, airships and bombers in the sky.

  4. IV

    Fight

    Turn-based battles on the world map. You see the enemy line-up first, then choose who fights. Wins bring experience, coins and the next part of the story.

  5. V

    Level up

    Every level and every population milestone opens bigger buildings and stronger units. A new level refills your energy, and the loop starts again on a larger scale.

Don't read about it. Build it.

Your first hour, in thirty seconds.

Pick a building, click a plot. Watch the bar at the top: the coins, wood, oil and people you make here are yours for the rest of the page.

Your island

Your advisorWelcome, Commander. Start with a few houses. People pay taxes.

A toy made for this page. The real island is bigger, the timers are longer and there are dozens of buildings for each job.

War

Bring the right army, not the biggest one.

Land, air and sea each have three classes. Every class hits one class in each branch hard and is badly hurt by another. Knowing the chart matters more than numbers.

Land Soldiers

Strong against

Artillery, Airships, Carriers

Weak against

Tanks, Bombers, Gunboats

Drill sergeantLook at their line-up first, recruit. Then bring what beats it.

  1. Scout. Open the world map and see the enemy line-up.
  2. Counter. Send the classes that beat it.
  3. Command. Each turn, pick one unit and one target.
LAND AIR SEA

Tap a class. Green beats it, red is beaten by it.

Trade

Your island mines one ore. Your army needs all five.

When you join, your island is drawn onto aluminum, copper, gold, iron or uranium. Your mines will only ever dig that one. Draw yours.

A busy harbour market with traders, crates and sacks of goods

The IMPERIUM Market

Players trade with each other right on top of the game. You never leave the page. Sell the ore you dig, buy the ones you can't.

  • Resources, units on your island, buildings and decorations can all be listed.
  • Goods sell in packs, cheapest unit price first.
  • Every trade is written to a ledger on the server.

Example listing, for illustration.

The story

They struck first.

Your island was attacked by the Dark Alliance. You rebuild, raise an army and take the fight to them, one island at a time. Each villain holds a piece of the world map and has to be beaten in a series of battles. You won't do it alone.

Your side

Chief advisor

The Advisor

Runs the tutorial and most of the story quests. Follow her arrows and the first hour takes care of itself.

“Houses first, Commander. An empire runs on taxes.”

Training

The Drill Sergeant

Teaches you to build units and to fight. Loud, blunt and always right about the enemy line-up.

“Biggest army loses to the right army. Every time.”

That's you

The Commander

Builds the town, gives the orders and leads the army across the map. Pick your own commander portrait when you sign up.

“One island at a time.”

Also on your staff: a city official for houses and government, an engineer for the big builds and a scientist for research.

Empire Points & IMP

Points with a real ledger behind them.

Gift points

Handed out for levels and quests. Spend them anywhere in the game. They can't be traded or withdrawn.

Withdrawable points

Earned by selling to other players. The only points the market accepts, and the ones planned to connect to IMP.

IMP is a token on Base. Withdrawable Empire Points are planned to convert to and from IMP, so what you earn from other players is yours to keep.

IMP runs on the Base test network today. Nothing about it is live or for sale yet.
