The Outer Worldsbase game was originally released in 2019, but the game also had DLC planned for a later date.The Outer Worlds: Peril on Gorgondebuted in September of 2020 with the option of buying it individually or as part of the Expansion Pass. The Expansion Pass includedPeril on GorgonandMurder on Eridanos, though not much was known about the latter DLC. Until today, players could only expect thatMurder on Eridanoswould follow Halcyon Helen’s “finest and final adventure.”The Outer Worldsreleased a new teaser trailer today forMurder on Eridanosthat gives players a better idea of what’s to come.

The trailer makes the audience feel as though they’re watching one of the serials mentioned inThe Outer Worlds.Halcyon Helen is one of the most well-known serial stars, though players don’t really see her in-game. Instead, she can be found on the loading screen that advertisesTerror on Monarch, a show warning the citizens of Halcyon about the dangers of a world without The Board. Halcyon Helen is played by Ruth Bellamy, but the trailer makes it seem that neither the character nor the actress will exist for much longer.

Intriguing New Plot

Many players ofThe Outer Worldswere fans ofPeril on Gorgonand its unique approach to DLC.Peril on Gorgonwas an immersive DLCthat felt like a self-contained story without being out of place inThe Outer Worlds. It was set up like a “pulp noir” story, with the Stranger in the role of a detective piecing together clues to uncover the truth of the Gorgon asteroid. There were lots of details to bring this genre to life in the game, including new music, sound effects, and mysterious atmosphere and lighting.

Murder on Eridanosseems to follow a similar style, though it might not be as “pulp noir” as the last DLC.The trailer remarks that a “special investigation”must be completed regarding Halcyon Helen’s murder, which may mean a few things for players. From what fans can glean from the trailer, the character of Halcyon Helen is dead, and possibly her actress Ruth Bellamy. This doesn’t exactly make sense becauseMurder on Eridanosis advertised as an aetherwave serial, meaning it’s an Odeon Pictures production and therefore fake. However, there wouldn’t be a breaking news announcement interrupting the moment Halcyon Helen is killed if it wasn’t a real murder and not scripted.

A Deeper Look at the Rizzo’s Corporation

Peril on Gorgonmainly focused on a deeper lookat the Spacer’s Choice facility on Gorgon and its dark past, andMurder on Eridanosseems to take a similar approach. This time, though, it will focus on Rizzo’s — the company that mainly produces Spectrum Vodka or things solely made from “purpleberry.” Rizzo’s also produced the Halcyon Helen series with the help of Odeon Pictures, making the immensely popular character the spokesperson for the company.

From the trailer, Halcyon Helen has lost a few people in her investigation including her partner and ex-partner. She’s fighting against “the Brain-Eaters,” which seems to be a new enemy for players toencounter on their trip to Eridanos. However, it’s possible these are just costumes and players will face regular enemies like Board soldiers behind the masks. The end of the trailer shows a door unlocking and Halcyon Helen’s face shifting before saying “it’s you.” This could mean that players should be on alert for the real villain hiding in plain sight during the Stranger’s investigation of Halcyon Helen’s murder.

For now, players can only guess whatMurder on Eridanoswill hold as far as plot and gameplay goes. However, one thing is certain — this special investigation is bound to hold a few surprises.

The Outer Worlds: Murder on Eridanosreleases July 12, 2025 for PC, PS4, and Xbox One.
