Big changes are in store for Big Brother.

The 16th cycle begins next week and in the tee-up to the return of the summer reality staple, CBS has announced this season's twists — and they're pretty significant.

This season two houseguests will win the Head of Household (HOH) title each week, a major tweak from the usual lone HOH. Being named HOH still has its perks, including the upstairs HOH suite. Because there will be two HOHs, each will have to nominate two houseguests for eviction each week. In a twist, however, winning HOH does not guarantee safety for the week.

Another twist comes in the form of fans influencing the game in a significant new way with an interactive element CBS is dubbing Team America.

There will also be a new high-stakes competition, the Battle of the Block, which the network promises will shift the power in the house week to week.

“When the houseguests learn about the new twists, they will need to throw out any pre-existing strategy if they want to survive in the game,” said Allison Grodner, executive producer of Big Brother. "The new Battle of the Block competition will shake up the power in the house like never before. A houseguest can go from zero to hero, or vice versa, every week!"

More twists and competitions will be announced during the June 25 premiere, which will be broadcast for the first time in HD.

Earlier on Wednesday, The Hollywood Reporter exclusively debuted first-look photos of the urban treehouse-themed house.
