But be careful, the invaders are pretty aggressive.
Use the same technology as the invaders, against them, and work together with probably the world's dumbest scientists to save the entire planet..Receive the technology weapon from the scientists, and fight the invaders in a level-based, FPS (first-person shooter), 3D game, to protect the earth. The earth is being invaded by foreign creatures, and you are the only one able to save the planet earth.
