  • Basic rules
    • Use photovoltaic arrays (solar panels) to create and power your turrets.
      • The solar panels must always face the direction of the sun’s rays to work.
        • If the sun’s rays move away from the panels, they stop working until the sun comes back.
        • Other objects (bugs, shields, meteors, and nearby turrets) may also cast shadows on the panels and cut their effectiveness.
      • The power created by your panels can be used to build turrets and more panels.
      • However, the power you earn is also used to fuel the turrets, which need energy to work.
    • Defend the planet from alien bugs using the turrets.
      • The planet’s center shows arrows indicating where the bugs appear.
      • The turrets automatically fire.
      • The fire rate of the turrets vary.
    • Use the shield for additional protection.
    • Defend the planet for as long as you can.
  • Hit points
    • Hit points appear at the center of your planet.
      • You start with 10.
      • Each time a bug crash lands on the planet, you lose a hit point.
    • Lose all your hit points and the planet is destroyed. Game over.
    • If a bug lands on a turret or solar panel, those are destroyed without harming the planet itself.

  • Guide
    • Opening moves
      • Build up your defenses by creating solar panels and turrets.
        • Focus first on creating between 2 to 3 solar panels and 1 turret.
        • Keep all your solar panels on one side.
        • Make sure to place turrets close to the panels to defend them.
      • Rotate the planet around so that the solar panels always face the sun.
        • You can also turn the planet around to make sure your turrets are always in a position to shoot.
    • Long-term survival.
      • Once you can afford the shield, place it in areas with no turrets (i.e. on the side opposite of the solar panels).
      • Make sure to keep generating ample energy to fuel your defenses.
      • Once you’ve gotten 4 or 5 panels running, focus now on adding more turrets.
      • See if you can cover the entire surface of the planet with turrets or shields.
• Target Audience
  • The game is suited for players who like spaceship shooting defense games.
  • The game has no adult themed content.
