Big Brother: Over the Top, the reality show's upcoming fall, online-only edition, will be quite different from the typical Big Brother.

Those who want to watch Big Brother: Over the Top can only do so through CBS All Access, the same way to watch the Big Brother live feeds during the summer. With no TV episodes and even more unfiltered access to what's going on in the house, this will be a very special edition of Big Brother.

Here's everything we know so far about Big Brother: Over the Top:

-12 new houseguests, plus a familiar face
 

Big Brother: Over the Top will feature 12 new houseguests in addition to a returning player. It was announced during the Big Brother 18 finale that viewers can vote on either Jason Roy from Big Brother 17 or Jozea Flores from Big Brother 18 to play again alongside these 12 newbies. You can go now to CBS.com and vote on either Jason or Jozea. You can vote every day until Tuesday, Sept. 27 at 3 p.m. ET. The winner will be revealed on Wednesday after the houseguests enter the house. Meanwhile, the new houseguests will be revealed on Monday.

-Weekday replays and full episodes
 

Keeping up with everything happening on the live feeds all day every day can be hard work, so Big Brother: Over the Top will show highlights from each day starting at 10 p.m. ET. Then there's a full episode that will "air" Wednesdays at 10 p.m. ET, recapping the week's major events.

-Brand new twists, competitions and ceremonies - all played out live!
 

HOH competitions and live evictions will take place on Wednesday nights, starting at 11 p.m. ET. Then there's a new Safety Ceremony that replaces the old Nomination Ceremony. The Safety Ceremony, where houseguests are revealed as safe for the week, begins on Saturday at 10 p.m. ET and concludes the following night on Sunday at 10 p.m. ET. This is when the nominations will be revealed. The Veto competition will be played on Monday at 4 p.m. ET and then the Veto meeting will take place Tuesday at 4 p.m. ET. We will get to see all competitions and ceremonies - which is a first for Big Brother.

-Live Diary Rooms
 

Considering there are no TV episodes, there would seemingly be no need for Diary Room sessions. However, Big Brother has found a way to include them on the feeds. We will get to see live Diary Rooms Tuesdays and Fridays starting at 10:30 p.m. ET.

-No jury
 

There won't be a jury voting on the winner of Big Brother: Over the Top. Instead, America will get to decide the winner of the season, much like the very first season of U.S. Big Brother back in 2000. Various countries, like the U.K., also have this format.

-Julie Chen is still involved
 

It's not yet known if host Julie Chen will be part of the weekly full episode, but she will be talking with houseguests every Thursday. She will also have an interview with the previous night's evicted houseguest on Thursday as well. The times on these interviews are not yet known.

Big Brother: Over the Top premieres Wednesday at 10 p.m. ET / 7 p.m. PT on CBS All Access.
