It is the fifth video Netflix has released for the start of season two.
The second season of the series, from writer, director and executive producer Hwang Dong-hyuk, follows Seong Gi-hun (Lee Jung-jae) as he returns to the game to try to destroy it from within.
The new trailer shows what's happening on the island this time with new characters trying to win the money with new games. One resembles a menacing version of tic-tac-toe, while another appears to take place on a horse-drawn carousel.
“We are not trying to harm you. We are presenting you with an opportunity,” one guard ominously says in the trailer.
Lee Jung-jae returns as Seong Gi-hun and is joined by Lee Byung-hun, who plays Front Man, the game's leader; Wi Ha-jun, who plays Hwang Jun-ho, a detective who sneaks into the game looking for his brother; and Gong Yoo, who plays the Recruiter, who initially invited Gi-hun to play the game.
New players include Yim Si-wan, Kang Ha-Neul, Park Sung-hoon and Yang Dong-geun, as well as Park Gyu-young, Jo Yu-ri, Kang Ae-sim, Lee David, Lee Jin-uk, Choi Seung- hyun, Roh Jae-won and Won Ji-an.
