About Orbit Defender
Orbit Defender puts you in control of Earth's Planetary Defense System. You build orbital turrets to protect the planet from asteroids and manage your funds according to the situation.
Weapons
You can buy and build your defense system from four weapons:
- Rocket Launcher: deals high damage, has low range and costs little.
- Laser Cannon: has long range, deals moderate damage and costs a medium amount.
- Shield Cannon: deals moderate damage, has a wide range for hitting multiple incoming asteroids and costs a high amount.
- Homing Launcher: fires rapidly and deals high damage. Its missiles follow their targets, making them unlikely to miss unless an asteroid has already hit the planet. It costs a very high amount.
Passive upgrades
Two passive options can improve your income and strengthen your defense system over time:
- Money Printer: generates $1 per second and can be purchased multiple times at a medium price.
- Health Generation: generates 1 HP per second and costs more than the Money Printer.
