We always knew they were coming back. Using recovered alien technology, the nations of Earth have collaborated on an immense defense program to protect the planet. But nothing can prepare us for the aliens' advanced and unprecedented force. This Alien mothership is more than twice the size as the last one and once again, the world's armies must band together to save the world. Do they have enough firepower or will this battle change and will aliens take over? Only the ingenuity of a few brave men and women can bring our world back from the brink of extinction.
