While the red-faced platform holder managed to pull the content promptly, many were still able to download the file, and subsequently have bombarded the Internet with spoilers and unannounced details about the game.
Obviously we won't spoil anything here, but one tid-bit did strike us. According to reports on NeoGAF, the final game's campaign mode will be offered in three unique guises: Action Mode, Story Mode and RPG Mode.
In a move to accompany all types of gamers, Action Mode is described as an option "for those who want to emphasise action and combat and minimize story management. Action mode will set automatic replies in conversation and a normal difficulty". Doesn't sound like Mass Effect, but sure, nice to have the choice.
Those that want to avoid combat but focus on the narrative will be at home with the game's Story Mode. This is pitched "for those who want to emphasize story immersion and minimize combat pressure. Story mode will set manually-selectable replies in conversation and a minimal combat difficulty". Seeing as the combat in Mass Effect 2 was terrible, this option actually sounds tempting to us.
But what about those that want the best of both worlds? No problem, Mass Effect 3's RPG is "for those who want to explore both realms of story and combat. RPG mode will set manually-selectable replies in conversation and a normal combat difficulty".
Bioware's Jesse Houston used the company's official forums to reassure fans that the game is still unfinished, with the "leaked" campaign modes still being iterated upon.
"We'd like to stress that the leaked code is in a rough, unfinished state and was not meant for public release. The content is not final, and is not reflective of the quality of the finished, polished game due for release on March 6, 2012 (March 9 in Europe).
"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'. We want to stress that these features are still in the early stages of development and will receive considerable iteration and refinement. These modes are designed to give players an even finer degree of control over their game experience than ever before.
"Whether it be someone who finds the combat difficult but wants to experience the amazing story, someone who wants to focus on the action and combat game play, or fans who want the rich, story-driven RPG Mass Effect experience they've come to love - Mass Effect 3 will support all of these options. We'll have more info in the days ahead."
