The cancelled Mass Effect: Universe was reportedly designed to treat the trilogy’s many decisions as the foundation for a much more flexible follow-up. New details suggest players could have created branching timelines, while also exploring a galaxy rebuilding itself after the events of Mass Effect 3.
The project’s closure followed BioWare’s shutdown and the end of years of work on the next entry in the studio’s science-fiction series. An internal trailer later surfaced, showing a customisable new protagonist alongside original-trilogy character Liara T’Soni.
Romain Toutain, the franchise’s technical director, discussed the trailer during a Twitch stream. French-speaking fans were assisted by an English-subtitled clip shared by ✨Lou🖤🤍💜 (@loustica-lucia), with the original post dated 2026-10-24T22:43:56.560Z.
A Mass Effect game built around player choice
Toutain confirmed several details associated with the leaked footage. The protagonist would have been customisable, although he did not reveal the character’s intended name. He also teased lore explaining how the Mass Relays could be repaired after their destruction at the conclusion of Mass Effect 3.
The trailer’s close-quarters combat was not merely cinematic. Players would apparently have been able to shift between firearms and hand-to-hand attacks during play, giving the new entry a broader combat style than the series had previously shown.

What “generate” timelines could have meant
The most substantial revelation concerns the way Universe would have handled decisions from the first three games. Toutain described a system in which players could combine choices from their saves to produce different timelines, explaining the significance of the project’s title.
“All the choices made in the first Mass Effect games were taken into account,” Toutain said, describing timelines that could be generated in a way loosely comparable to Zero Time Dilemma.
The idea went beyond the three-choice world-state import associated with Dragon Age: The Veilguard. Toutain compared it loosely with Dragon Age Keep, the online tool used to prepare world states for Dragon Age: Inquisition, but said Universe would have allowed decisions to contradict actions already taken.
In practice, that meant creating branching points rather than simply importing one fixed history. The game’s systems were intended to track the state of the world and assess whether a sequence of events remained logically valid.
Systems designed to keep missions moving
Toutain described a system capable of checking the consequences of a player’s actions. If a character was killed but was required for a later mission, the game could determine whether to preserve a route to completion, fail the mission as a direct consequence, or alter a future event so another path remained available.
He said the underlying technology was difficult to establish but worked effectively in testing. The goal was to give players “absolute autonomy” while ensuring the game could respond to an unusually large number of possible world states.
That kind of reactive design is also relevant to the branching logic found in interactive entertainment more broadly. Readers exploring their own playable projects can compare the planning involved with RETROCADE’s DIY arcade kits, arcade parts and arcade machine buying guide.
Inside the leaked trailer
Toutain clarified that the footage was never intended for public release. It was an internal trailer created to communicate the project’s mood to the wider studio, which explains why it used “Quartz” by French 79 instead of original music produced by BioWare.
He also identified the squid-like creature that prompted speculation about a biological Reaper asset. Its internal name was reportedly “Billy”.
Fans call for the project to be saved
Following BioWare’s closure, members of the Mass Effect community began campaigning for EA to sell the studio and its intellectual property so the game could continue elsewhere. A Change.org petition urges EA to “save” the project.
Toutain was pessimistic about that prospect, saying he did not expect EA to sell the studio or its properties. In his view, the company was more likely to shut projects down while retaining the licences.
