First steps when you join

Step
In short Getting buildings down early is the fastest way to secure a steady cash flow.

When you first join, you automatically earn the Welcome badge. From there, place buildings so your cash income starts growing. Once your income feels stable, you can move on to buying weapons.

  1. Place buildings every building you put down adds to your cash income, so fill your base with them from the start.
  2. Open the shop buy missiles, drones, or aircraft for attacking enemies.
  3. Add defenses place defensive structures alongside your income buildings so attacks from other players do less damage.
  4. Check your progress you earn the Empire Builder badge after placing 25 buildings.

Keeping cash growing

Tips
In short The more buildings you have, the faster your cash climbs — even while you are offline.

Your base earns cash continuously, including while you are logged out. That means every time you come back, you have a pool of cash ready to spend on more buildings or weapons. Reaching one million dollars earns you the Capitalist badge.

Tips worth knowing
  • Place new buildings every time you log in to keep compounding your income.
  • Hitting 25 placed buildings unlocks the Empire Builder badge.
  • The Capitalist badge requires earning one million dollars total.

Attack and defense — keeping the balance

Table
In short Pushing hard on offense while ignoring defense leaves your income buildings exposed, so develop both sides together.

Destroying enemy buildings cuts their cash income, giving you a competitive edge. At the same time, a base with weak defenses can be torn apart by other players. Alternate between strengthening your offense and shoring up your defenses as your cash allows.

Offensetargeting enemy buildings directly reduces their cash income.
Defensedefensive structures absorb incoming attacks and protect your income buildings when you are not online.
