Emma, who presents the reality series, and Rylan, who co-hosts BB's Bit On The Side, are dressed in smart army uniforms while robotic servants scurry round them in a futuristic house.
The trailer explains this year's 'Power Trip' theme perfectly, with Emma saying: "Everybody is just so nice nowadays. They're all so happy to please."
Brandishing a whip, she continues: "I want the plotters, the schemers. They're so much more fun. After all, there's no 'i' in team."
Rylan can also be seen kicking over a servant that has been polishing his boots.
Yesterday, it was revealed that Big Brother will start with a double-bill launch show, airing over two nights on Thursday 5 and Friday 6 June.
Big Brother: Power Trip will encourage this year's housemates to get ruthless and seize and maintain power, while viewers will also get the chance to manipulate the contestants.
The famous house has again been given a drastic makeover, meaning this year's compound will have a futuristic feel with "stark open spaces and sleek clean lines". There will also be a heavy focus on technology.
