The season 2 premiere of "Westworld" is inching closer, and HBO has already unveiled a few video teasers for its hit science fiction thriller series. The details about the new plotline and fresh faces in the second season are mostly being kept under wraps, although the recent trailer may have spilled some hints. For one, the latest "Westworld" season 2 trailer has a hidden code that will lead to four more theme parks.

The first season of "Westworld" had a rich content that the creators may be able to expound the story further in season 2 and show the viewers many things that they have not seen before. There is a possibility that there are many other theme parks aside from Westworld that are just waiting to be found. Interestingly, the latest season 2 trailer has a hidden binary code which can be deciphered to get the Delos Destinations' fictional website. Upon visiting this website, the fans will know more about the company, plus the fact that is currently in control of four more theme parks other than Westworld.

It was teased back in season 1 that there are a Wild-West and a Samurai World theme park, although it appears that the fans have not yet seen all of the theme parks in the "Westworld" universe. There is not enough information in the Delos Destinations website to know what its four theme parks look like. As for the Samurai World, it was reported that Japanese actor Hiroyuki Sanada will play the role of Musashi, who belongs to the said theme park. It has yet to be seen if Musashi also has some business to do in the Westworld theme park.

Meanwhile, The Hollywood Reporter gave a caution to the "Westworld" fans that some scenes in the Super Bowl ad for season 2 may not appear in the show. It is rumored that some of the footages from the Super Bowl teaser are not intended to be aired on the actual. These scenes were just filmed for the purpose of giving the Super Bowl viewers a great preview of "Westworld" season 2. This could also be HBO's way to keep the major plot details as secret, given that the fans were able to deduce a lot of plot twists in season 1 just by analyzing the trailers.

"Westworld" season 2 will premiere on April 22nd, 9 p.m. EST, on HBO.
