Ender’s Game
It is 2086. Fifty years ago the earth was attacked by the Formics, an ant-like alien species. They wiped out a significant part of the Earth’s population before being stopped kamikaze-style by the legendary human pilot Mazer Rackham. Though the Formics have not returned, an attack is still feared. Hence, the people of Earth need to be battle ready: they need a new Mazer Rackham.
