With the second half of the year fast approaching, fans of the 2016 Netflix breakout series "Stranger Things" are anticipating the show's sophomore run. "Stranger Things" Season 2 is set to debut this October, bringing back the original cast, together with some new faces.

The story is set a year following the events of the death of the Demogorgon and Eleven's mysterious disappearance. When the show returns, viewers will get to see the band of young brothers finally reunited with Will Byers, who is still dealing with his experience in the Upside Down.

Recently, executive producer Shawn Levy shared that they're already in the editing process of production and that the upcoming season will be a lot stranger than their debut run.The show will touch on government conspiracy themes, TV Line reported. Levy told TV Line, "We wanted to explore the idea of how they could keep something like this covered up and what happens if you’re not able to keep a lid on this."

Shawn Levy teases 'darker' season 2

Following the events of the first season, it became clear that the government in Hawkins holds deep and dark secrets that involve human experiments, resulting in weapons such as Eleven and odd realities such as the Upside Down.

While talking to The Hollywood Reporter, "Stranger Things" season 2 executive producer Shawn Levy admitted that the sophomore run of the show is indeed "darker" and "more ambitious" than its predecessor.

He shared, "The threats to Hawkins and to our characters are bigger, darker, often times scarier."

Sophomore season will be more terrifying but has 'heart'

One of the best things to come out of the Netflix hit series is the amazing chemistry between the cast. This enabled them to tell a story like no other and showcase true character development.

David Harbour recently opened up about how his character, Chief Jim Hopper will have to deal with the repercussions of his heroic acts during season 1. This definitely built relationships between him and the Byers family, as well as Eleven. As per Shawn Levy, "Stranger Things" season 2 "got the best heart," which fans may also look forward to seeing.

More of Eleven's back story

In the debut season of "Stranger Things," viewers were let in on how Eleven was created as a weapon by the Hawkins Laboratory. The reason behind this was unclear, but back in February, co-creator Matt Duffer admitted that "Stranger Things" season 2 will "get into [Eleven's] story and backstory. We learn about where she came from and how she came into the world and the program that resulted in her." Such programs are definitely part of some government conspiracy in Hawkins, and viewers will get to see more of that when the show returns on October 31.
