Downloadable content included on disc, 6 hour exclusive mission clarified
Since Mass Effect 1 will remain an Xbox 360 exclusive, PlayStation 3 owners will have the option of playing an interactive comic included with Mass Effect 2 to help bridge the gap between the two titles.
Clarifying a recent post made on the official BioWare German forums, producer Jesse Houston confirmed the comic would be exclusive to PS3 at its initial release for players who would be otherwise "unable to realize the full effect of choice in the Mass Effect universe." The comic can be downloaded through the Cerberus Network.
"While I can't release all the details about this yet, what I can tell you is that we want to create a stunning visual experience that not only tells the core story elements of Mass Effect 1, but also is fully interactive allowing you to be faced with some of the major choices which will have consequences your [sic] Mass Effect universe," Houston said.
Mass Effect 2 for PS3 also includes the previously released downloadable content Lair of the Shadow Broker, Project Overlord, Kasumi: Stolen Memory and the Blood Dragon Armor on the Blu-ray disc. The Zaeed and Firewalker content is also accessible through the Cerberus Network.
There will also be exclusive free and paid downloadable content for the PS3 version, such as the Recon Operations Pack, and bundled content like the Aegis Pack.
Houston also clarified the reported "6 hour exclusive mission" saying it was all a translation error.
"This I believe is a communication error lost in translation," he said. "When we talk about 6 hours of content we are talking about what's included exclusively 'On Disc' (Kasumi, Shadow Broker, Overlord), The Interactive Back Story and the Cerberus Network Access."
Mass Effect 2 for PlayStation 3 hits in January.
