Good Planet

A new planet has been discovered with great potential for life and development.... Unfortunately it lies within a volatile region of space and is under constant threat. It is up to you to defend the planet for as long as possible. The frequent waves of space debris and other unknown dangers must be held back. When the planet becomes to badly damaged all will be lost. Build, move, upgrade and sell turrets and satellites, collect resources and manage your defences effectively to protect this Good Planet from destruction.
