BIG BROTHER announces this summer's exciting new twist, "BB Takeover," featuring weekly surprise guests who will unleash new twists into the game each and every week. The season's special two-night premiere airs Wednesday, June 24 (8:00-9:00 PM, ET/PT) and Thursday, June 25 (8:00-9:00 PM, ET/PT) on the CBS Television Network. In addition, Houseguests this season will live in a modern steel beach house that features a towering Sky Bridge.

This summer's "BB Takeover" twist will feature a surprise guest each week who will appear on the show to announce a new twist into the game. Expecting the unexpected will be taken to new heights as Houseguests attempt to stay in the game amid the ever-changing twists that shake up life inside the house on a weekly basis. A special guest will appear on each night of the two-night premiere and reveal twists that could affect the cast and viewers.

"This is going to be the biggest BIG BROTHER ever! Surprise guests, twists every week all summer long and, of course, Zingbot!" said Executive Producer Rich Meehan. "But the Houseguests better keep their focus, because BIG BROTHER is all about relationships. Trust me, with all the twists and turns, those bonds will be more important than ever, because at the end of the week, it's your housemates that send you packing on eviction night."

This season, the BIG BROTHER Houseguests will live in a modern steel beach house that's the largest yet, with the addition of the "Sky Bridge," which adds 155 square feet of living space. Featuring a floor comprised of 12 clear Plexiglas panels, the bridge is not for the faint of heart, with its clear view to the first floor below. Also, Houseguests will enjoy the towering 22-foot-tall steel Wave Wall made of custom curved steel, wood and Plexiglas in the living room, which required the ceiling to be raised from 12 to 24 feet.

The details on the walls throughout the house will show "half-tone" finishing, similar to a comic book illustration, and one of the bedrooms will be dedicated to this edgy pop art style. While the downstairs area evokes the sea, upstairs is all about the sky. The Head of Household suite is essentially a skybox with transparent flooring and clouds everywhere, where the HOH will feel like they're literally floating on cloud nine. The beach theme continues in the bedrooms, with one filled with coral and driftwood and the other capturing the magic of the sea at night with the vibe of an upscale club.

Following the special two night premiere, BIG BROTHER will air Sundays, beginning June 28 (8:00-9:00 PM, ET/PT), Wednesdays (8:00-9:00 PM, ET/PT), and the live eviction show hosted by Julie Chen on Thursdays, beginning July 2 (9:00-10:00 PM, live ET/delayed PT).

BIG BROTHER follows a group of people living together in a house outfitted with 80 HD cameras - four more than last season - and more than 100 microphones recording their every move, 24 hours a day. Each week, the Houseguests will vote someone out of the house. At the end, the last remaining Houseguest will receive the grand prize of $500,000. BIG BROTHER is produced by Emmy Award-winning producer Allison Grodner and Rich Meehan for Fly on the Wall Entertainment, in association with Endemol Shine North America.
