This DLC for Mass Effect 2 is an expansion requiring the base game, blending Shooter and RPG elements. You join Commander Shepard to recruit Kasumi Goto, a master thief, leading to a new two-mission arc focused on infiltrating an arms dealer's vault to retrieve a partner's memory graybox. It enhances the core experience by adding a new squadmate and story content without introducing new core mechanics.
The primary addition provided by this DLC is the introduction of a new squad member for Commander Shepard: Kasumi Goto. Players must undertake missions to locate and successfully recruit this master thief, who is situated on the Citadel space station.
The storyline centers on Kasumi’s personal agenda. In exchange for her skills and loyalty to Shepard’s crew, she requests assistance with a complex heist. The target is Donovan Hock, a known arms dealer. Kasumi seeks to infiltrate Hock’s vault to retrieve a specific item: a "graybox." This device reportedly contains the stored memories and sensitive intelligence gathered by her deceased partner, Keiji Okuda.
This expansion includes two distinct new missions. These missions cover the process of recruiting Kasumi and the subsequent operation to infiltrate Donovan Hock’s stronghold. These objectives integrate directly into the existing narrative structure of the base game, providing new environments to explore and tactical challenges that flesh out the background of the new companion.
As a character-focused DLC, this content enriches the existing gameplay loop by adding a new companion. This means new dialogue options, potential loyalty development within the established framework, and the combat capabilities of Kasumi are added to Shepard's tactical options.
The content does not introduce entirely new core gameplay mechanics or systems separate from the established third-person shooting and role-playing choices that define the main title. The scope is focused on delivering a specific, self-contained story arc centered on the new character, adding depth to the roster rather than fundamentally altering the game world.
Players will continue to engage in the familiar blend of squad management, dialogue-driven decision-making, and tactical combat missions. The focus remains on advancing the overarching galactic conflict while exploring the specific motivations of the newly recruited operative.
This specific content package, Kasumi - Stolen Memory, is a singular addition and does not contain any further associated DLCs or expansions bundled within it.
