Next month, HBO's hit series Westworld is returning for a much-anticipated second season. In building anticipation surrounding the upcoming episodes, today we receive the official trailer for season two.

Set to an orchestral cover of Nirvana's “Heart-Shaped Box,” the dramatic footage ensures a reckoning is on the way, with a robotic uprising. Humans and hosts will no doubt be at war throughout season two, as you can get a feel for what to expect by pressing play above.

As Westworld's inaugural season ushered in the adaptation of Michael Crichton’s 1973 film of the same name, the second season will seemingly center around six different parks, including Shogun World, which was referred to as Samurai World in the original picture.

Westworld season two premieres on HBO April 22.

In other TV news, the third season of 'Stranger Things' will feature more "Dad Steve" and middle school romance.
