This DLC for Mass Effect 3 is a narrative and gameplay extension requiring the base game. You undertake a mission to stop Cerberus from seizing a Prothean artifact on Eden Prime. The core addition is the last surviving Prothean as a permanent squad member, offering new tactical depth, alongside the Prothean Particle Rifle and new cosmetic options for all existing companions. It integrates directly into the main campaign, deepening the lore surrounding the Prothean Empire.
The central conflict of this content involves the hostile organization Cerberus launching an attack on the human colony of Eden Prime. With Alliance forces heavily committed to the war against the Reapers, support is unavailable. Intelligence suggests Cerberus is targeting a newly discovered Prothean artifact on the planet. Players take control of Commander Shepard to infiltrate the compromised colony and secure this ancient technology before Cerberus can exploit it.
The atmosphere is tense, reflecting the immediate danger posed by Cerberus infiltration while the galaxy faces existential threat. The storyline provides significant insight into the final days of the Prothean Empire, offering context to their downfall at the hands of the Reapers.
The most significant addition is the introduction of a powerful, permanent new squad member: the last surviving Prothean. This character joins Shepard’s crew, bringing unique perspectives and abilities to the ongoing fight. Integrating this character into the squad composition alters tactical options available during missions.
Beyond the new companion, the content pack includes:
This content is designed as an extension of the main role-playing shooter experience. It is not a standalone adventure but rather a crucial chapter woven into the existing structure of the parent title. The inclusion of a new squad member and weapon directly impacts combat encounters and squad customization throughout the remainder of the campaign.
As a focused downloadable content release, this package is not comparable in scope to the full base game. It provides a specific, self-contained narrative arc centered on the Prothean discovery and the immediate threat posed by Cerberus. Its quality is generally considered consistent with the narrative and tactical shooter elements established in the parent title, offering substantial lore development and a valuable new tactical asset.
This content is categorized as DLC, meaning it requires the base game, Mass Effect 3, to be played. It enhances the existing tactical shooter and RPG mechanics by adding new strategic depth through the new squadmate.
