Sega Stormrise - PS 3

Stormrise is a real-time tactics video game developed by Creative  Assembly's Australian studio and published by Sega. The game is a real-time tactics game, with the ability to control units in the air, on the surface, and underground. In the near future, a network of orbital weather control satellites was created to prevent an environmental disaster. But, the satellites malfunctioned triggering a catastrophic event known as simply "The Event", in which firestorms ravaged the surface of the Earth. A select few were chosen to go into cryogenic stasis and rebuild society, while the rest were left to die. After a few decades, two civilizations began to emerge. Those who went into stasis would reawaken and form the technologically advanced Echelon, while those who were left behind would adapt to the new environment and become the tribal Sai. It's set in a post-apocalyptic world. The Echelon: A technologically advanced race that endured the planet's fallout by way of cryogenic stasis.
The Sai: A tribal society that adapted to the new environment and evolved.
