I am appreciated that you are willing to play . This game is set in a near future, when you are one of the defense force belong to the Earth, and you have to defend the Earth from the alien invasion. Hope you can play the game again and again, and try to memorize how enemies act to progress the game. Then enjoy the game. At first I only thought about making the game. Then I push this game go through multiple updates. Finally it becomes this game, and it has been totally different from the origin...
