A summer of gaming, alliances, and deception is underway.

“Big Brother” is set to premiere this week. For Season 27 of the hit reality competition series, the official theme will be “Big Brother: A Summer of Mystery,” CBS confirmed Wednesday, July 2.

In addition to unexpected twists and turns, CBS said the season will include a “masked visitor, a secret accomplice and the shocking arrival of a “Mystery Houseguest” whose identity will remain under wraps … at least for now.”

Until then, here’s what we know about the confirmed cast of “Big Brother” Season 27:
