Fracture

Fracture is an upcoming video game for the PlayStation 3 and Xbox 360 by Day 1 Studios, and is currently scheduled for an October 7th release in North America and a European release on October 10th.
Global warming and the search for methods of combating its effects have split the United States, and the world, in two. In the east is the Atlantic Alliance, a staunch supporter and leading innovator of cybernetic solutions to the world's problems. Their adversary is the Republic of Pacifica and their Pacific Rim allies in the west. They advocate adapting the human genome to cope with the changing world. Both factions are armed with a new type of tectonic technology that allows armies to raise and lower defenses out of the earth at any location of their choosing.
