Activision's "Call of Duty" transports us into a future dystopia that's both terrifying and believable in another "documentary" for the game, this time promoting its much-anticipated launch, Black Ops 3.

The teaser trailer, "Ember," by 72andSunny creates a timeline from the 1990s stretching into the late 21st century, combining both real news clips and live-action footage, showing how technology takes us into an era where "modified" athletes compete in the Olympics, consumers buy retinal chips at the mall and protestors rail against a kind of evil Big Science. There's also a suggestion that all this technology has created some kind of "super soldier" using technologies such as neural connection and bionic limbs. The film ends by asking, "How far will we go?"

A longer trailer will be out this weekend, while Black Ops 3 itself will be released this fall.
