A 13-minute video of Mass Effect 3 gameplay leaked due to "human error" on Microsoft's end this past Friday. According to BioWare, ME3 content that was meant for internal beta testing was flagged incorrectly and sent to people who signed up for the beta of the Xbox Live dashboard update. While the leaked code was in a rough, unfinished state, a new story feature was one of the things that particularly caught our attention.
It's not up anymore, but the video showed various areas and characters in the game, including Commander Shepard and Captain Anderson during the Reaper invasion on Earth and another part featuring Shepard, Liara, and Garrus escorting the quirky Mordin and a Krogan.
"One feature that was present in this early build is a set of game play modes that are in development. In the beta code they are referred to as “action mode”, “story mode” and “RPG mode," said BioWare's Jesse Houston on the Mass Effect 3 forums.
