The game is due out later this year and features online multiplayer action in a massively multiplayer FPS setting. In Firefall, Earth has been plunged into a dark age known as the Nine Year Winter. This was the direct result of an asteroid colliding with Earth - an asteroid that was predicted by astronomers to be a 'near miss'. A substance known as crystite is discovered in the planet, allowing factions to generate nearly unlimited amounts of power. Events proceed and eventually the Arclight is built. This is a massive ship, sustained by two crystite reactors, nearly the size of an entire city.
The Arclight was the result of a collaboration from nearly every world power, but its maiden voyage couldn't have gone more wrong. As the Arclight began to "fold space" in its journey, something went wrong and a massive tear was rent in the fabric of the universe, creating the Melding - a giant energy storm that is pouring out of the rift and transforming all life it comes in contact with.
In the cinematic intro above, the Arclight itself comes crashing down from above onto Brazil down below. For more on Firefall, check out http://firefallthegame.com/. Enjoy!
