# List of Mr. Robot episodes
**Mr. Robot** is an American techno-thriller drama series that aired 45 episodes in four seasons on [USA Network](https://www.edgepedia.org/usa-network) from June 24, 2015 to December 22, 2019[1](https://televisionstats.com/s/mr-robot/episodes) • [2](https://tvseriesfinale.com/tv-show/mr-robot/). Created by [Sam Esmail](https://www.edgepedia.org/sam-esmail) and starring [Rami Malek](https://www.edgepedia.org/rami-malek) as the hacker Elliot Alderson, the series is as recognizable for its episode titles as for its plots: each episode carries a filename-style title such as **eps1.0_hellofriend.mov**, and the file extensions change meaning season by season, from video formats to encryption programs[3](https://www.thewrap.com/mr-robot-how-a-change-in-season-2s-episode-titles-could-be-key/).

| Series run | June 24, 2015 to December 22, 2019; 45 episodes in 4 seasons on USA Network[1](https://televisionstats.com/s/mr-robot/episodes) • [2](https://tvseriesfinale.com/tv-show/mr-robot/) |

| Title format | Filename-style titles of the form eps[season].[episode]_[title].[extension], such as eps1.0_hellofriend.mov[1](https://televisionstats.com/s/mr-robot/episodes) |
| Extension themes | Season 1: a different video extension for every episode; Season 2: encryption-program extensions such as .tc (TrueCrypt)[3](https://www.thewrap.com/mr-robot-how-a-change-in-season-2s-episode-titles-could-be-key/) |

| Emmys | The pilot won Outstanding Music Composition for a Series (Mac Quayle, 2016); the series was nominated for Outstanding Drama Series in 2016, and Rami Malek won Outstanding Lead Actor[7](https://www.emmys.com/shows/mr-robot) |
## Title conventions
Every regular episode title imitates a computer filename, in the pattern eps[season].[episode]_[title].[extension], so that season 1 episode 1 reads eps1.0_hellofriend.mov and season 1 episode 4 reads eps1.3_da3m0ns.mp4[1](https://televisionstats.com/s/mr-robot/episodes). The titles are not purely decorative. As an analysis in *TheWrap* put it, the cryptic titles often contain references to computer terms that double as clues to the story and its themes[3](https://www.thewrap.com/mr-robot-how-a-change-in-season-2s-episode-titles-could-be-key/).
**A clue in the extension.** The clearest example is "eps1.3_da3m0ns.mp4". A daemon is software that operates in the background of a system without any user input; daemons play a central part in the episode and additionally function as a hint toward the major twist closing out season 1, when it is revealed that [Mr. Robot](https://www.edgepedia.org/mr-robot) exists only inside Elliot's mind, a daemon his brain had been running without his awareness.[3](https://www.thewrap.com/mr-robot-how-a-change-in-season-2s-episode-titles-could-be-key/)
The extensions themselves carry meaning. Every episode title in season 1 ends in a different video extension: the pilot comes in a QuickTime MOV format, and the finale comes in Microsoft's phased-out AVI. In season 2 the formats changed to encryption extensions, beginning with the premiere title "eps2.0_unm4sk-pt1.tc", native to the obsolete encryption program [TrueCrypt](https://www.edgepedia.org/truecrypt), with other titles referencing programs like KeepSafe, SmartEncryptor, and Android's encryption system[3](https://www.thewrap.com/mr-robot-how-a-change-in-season-2s-episode-titles-could-be-key/).

## Season 3 (2017)
Season 3 premiered on October 11, 2017[4](https://ckmusicdesign.nl/userfiles/file/metagulef_jezoga.pdf).

USA Network announced the fourth season's renewal on December 13, 2017, the same day as the season 3 finale[12](https://mrrobot.fandom.com/wiki/Season_4).
## Season 4 (2019)
The fourth and final season premiered on October 6, 2019 and ran 13 episodes, concluding December 22, 2019[4](https://ckmusicdesign.nl/userfiles/file/metagulef_jezoga.pdf) • [1](https://televisionstats.com/s/mr-robot/episodes).
**"407 Proxy Authentication Required."** The seventh episode, aired November 17, 2019, is the season's centerpiece. Presented as a five-act stage play, this bottle episode takes place entirely within Krista Gordon's home, where Fernando Vera holds Elliot and Krista hostage and, through a brutal psychological interrogation, forces Elliot to confront a repressed childhood trauma involving his father, Edward Alderson. The episode holds a near-perfect 9.9 rating on IMDb[6](https://shapes.inc/fandom/mr-robot/episodes-guide).
The series ended on December 22, 2019 with the final episodes broadcast as "Series Finale Part 1" and "Series Finale Part 2"; the concluding episode carried the title "Hello, Elliot"[2](https://tvseriesfinale.com/tv-show/mr-robot/) • [13](https://www.aceshowbiz.com/tv/mr_robot/episode.html) • [14](https://www.alecbojalad.com/s/The-Best-TV-Episode-Numbers-of-All-Time-Den-of-Geek.pdf).
## Reception of the run
Every season earned a 90% critics' score or higher on Rotten Tomatoes, with season 1 highest at 98% and season 2 lowest at 90%[5](https://www.rottentomatoes.com/tv/mr_robot). On the TMDB-based ratings compiled by TelevisionStats, the average episode score rises season by season, from 7.9 for season 1 to 8.1, 8.4, and 8.6 for seasons 2, 3, and 4, with the season 4 stretch of episodes 5 through 9 scoring 9.1, 8.5, 9.2, 8.6, and 9.0 and episode 7 the series' best at 9.2[1](https://televisionstats.com/s/mr-robot/episodes).
The second season remains the contested one. According to a *Time* retrospective, the first season won universal acclaim, but each episode of the divisive second season grew stranger and more daring while losing a bit of its hold on viewers, and that season landed on far fewer year-end "best TV" lists than the first.[15](https://time.com/7299891/mr-robot-netflix-legacy/) The same retrospective credits the show's run of experimental episodes from season 2 onward, when Esmail took over as full-time director: a 15-minute 1990s sitcom parody, an entire installment presented as a single shot during a riot, and a hostage situation structured like a five-act play[15](https://time.com/7299891/mr-robot-netflix-legacy/).
