BattleField

It is the year 3098, and Earth has been destroyed by pollution and global warming. Humans filter air and water and are forced to live in artificial environments on Earth's dry surface. A partnership with their allies is their only means of survival. Science is on a verge of a breakthrough that will save the planet, Maintenance keeps the cities functioning and BattleField—made up of Earth's heroes—defends Earth and its allies to ensure a brighter future.
When two BattleField recruits, teenagers Tom and Brent, intercept a missive of war, they embark on a mission to save the human race.
