The first full-length trailer for the second season of HBO's Westworld offers a look a the rise of the machines, and a glimpse of the much-teased feudal Japan theme park, ShogunWorld.

At the end of Season 1, the Hosts gained sentience and freedom to do as they please, which unfolds in different ways. Dolores (Evan Rachel Wood) leads a revolution into other worlds in the park, with hapless lover Teddy (James Marsden) along for the ride. Maeve (Thandie Newton) searches for her missing daughter, whom she believes is somewhere in the park. And the humans trapped there will have to come together for their survival and shut down the revolt before it gets out of hand.

Backed by a haunting rendition of Nirvana's "Heart-Shaped Box," the trailer shows the chaos of the Hosts across Westworld. In additiona to ShogunWorld, more areas of the park have been teased for the second season of Westworld, although their names and details haven't been revealed.
