The final season of the critically-acclaimed drama series Mr. Robot, starring Academy Award winner Rami Malek, will say "Goodbye, Friend" beginning Sunday, October 6 at 10/9c with 13 all new episodes. Mr. Robot goes on to say this in the first trailer released for new episodes.

"If you go down this path, it'll never end. It will always be something else. Another symbol to destroy, more people to save. This is an endless war. What you're about to do is crossing a line. Elliot's response? RELATED: Mr. Robot Will End with Season 4 in 2019

"It's a little late for that, don't you think?"

Set during the 2015 Christmas holiday, the fast-paced season will be one filled with answers, hacking and blood. Check out the first official trailer featuring Elliot (Rami Malek) and Mr. Robot (Christian Slater) getting back to work and down a path that could prove endless. But have they crossed a line?

Mr. Robot follows Elliot Alderson (Malek), a cyber-security engineer who, along with Mr. Robot (Slater) and fsociety, starts a revolution to change the world. Season 4 will pick up where the third season finale left off, delving into the pros and cons of Elliot hitting "send" on the email that could reverse 5/9.

The series stars Academy and Emmy Award winner Malek, Golden Globe(R) Award winner Christian Slater, Portia Doubleday, Carly Chaikin, Martin Wallstrm, Grace Gummer, Michael Cristofer and Emmy Award nominee BD Wong. Mr. Robot hails from writer, director and executive producer Sam Esmail, as well as Anonymous Content executive producers Steve Golin and Chad Hamilton. Sam Esmail had this to say about Elliot's ultimate endgame.

"It brings the show back to its initial promise of Elliot wanting to take down the guys behind the scenes who are manipulating society. The journey between seasons one to three has been about discovering who the real culprits are. The hack was merely a distraction that was co-opted by these people, and it's finally been revealed and exposed to Elliot. In a weird way, the next season will return back to that initial premise of the show and have Elliot be motivated by that, with this new clarity."

Esmail went onto say this about entering the final season.

"Whenever I talk about Elliot's emotional journey, it really is about this relationship with Mr. Robot, that needs to face its reckoning at some point. The ending of [season three] pivots them to working together as a team for the first time in a genuine way. There's this realization that they are pieces of one whole, and it's something we haven't quite seen before, especially given the tumultuous relationship they had together in season two, and then here in season three when they didn't speak with each other for basically the entire season. We've now finally brought them to a point where they can work together as a team - and dare I even say, integrate."
