Leaked Mass Effect 5 trailer surfaces online after BioWare studio closure

A former BioWare employee posted leaked footage of the cancelled Mass Effect 5 online after BioWare’s studio was shut down and EA officially ended development of the project, the leak reportedly appearing on Reddit and surfacing after the studio closure.

The footage, described in the leak as a trailer, was reportedly produced from pre-production and in-game assets by a small development team and appears to have been prepared internally months before the studio’s closure. The clip carries the reported title "MASS EFFECT UNIVERSE" and finishes with a "Coming Soon" notice, but those who shared it and observers have not verified its authenticity.

Posts sharing the material identified the source as a purported BioWare developer and suggested the project was further along than initial planning, though no independent confirmation of development status has been provided. The leaked footage is said to be largely cinematic in presentation, relying on CGI sequences rather than playable sections.

Observers of the trailer noted that the small amount of gameplay-like material is embedded within cinematic segments rather than shown as standalone play, reinforcing the characterization of the clip as a cinematic teaser rather than a gameplay reveal. The reported internal title, "Mass Effect Universe," was shown in the material and has been described as a possible internal name for the project.

According to the leaks, roughly 50 developers from BioWare’s Austin office had been working on the title before the studio's closure. The material was reportedly created using pre-production assets and in-game elements produced by that small team prior to EA’s decision to end development.

EA’s formal decision to end development and the subsequent studio shutdown mean the series currently has no future under the circumstances described in the leak; the source states the project has been cancelled. Fans have reacted by starting petitions and expressing hope that EA may either continue the project or sell the Mass Effect intellectual property to another studio.

EA and BioWare have not issued an official statement about the leaked footage or its authenticity, and the provenance of the posted trailer remains unconfirmed.
