Planet Defender

Welcome General, We have been waiting for you. Alien attacks are imminent and the entire earth's resources are ready at your disposal to stop the invaders for once and all. All systems has been consolidated into one command console that you can see in front of you and all commands can be issued using your mouse. On the left part you will see Earth surface and all defense points organized as a grid for your ease of monitoring. These defense points are currently empty but all hands and equipments are ready to build whatever you order us to build. To the right you will see selection panels, which allows you to choose what to build, upgrade and research. It also tells you the total number of people you have working for the defense initiative, as well as the money you have to spend in building, upgrade and research. Remember that your people is the most important element in your defense. They are the ones who work to earn money for this command and they are also the ones who do the building, upgrading, research and fighting. If all of them are killed by the aliens, the earth is lost. This does not mean that you cannot afford to lose anyone though; the citizens of earth know that war always cost lives and more and more people are coming to join us by the second so our numbers can sustain some loss and even grow larger. Issue your orders now general; our lives is in your hands
