A post to the BioWare Social Network addresses reaction to the recent leak of details on From Ashes, a day-one DLC pack for Mass Effect 3. With some suggesting a boycott over the news (thanks Jason via PCWorld), BioWare's Mike Gamble wants it understood that this content was developed after the game:

As most of you know, yesterday there was a leak that revealed the upcoming DLC “ME3:From Ashes” on the Xbox LIVE Marketplace. This leak took place before we were prepared to make an announcement about the details of that pack (slated for this Friday). There has been a lot of discussion about the DLC offering but we wanted to clarify a few things...

- “From Ashes” includes the Prothean squad mate, an adventure on Eden Prime, a new weapon, and an alternate appearance for every squad mate. Note that these alternate appearances are in addition to the ones already advertised in the CE.

- The Collectors Edition has been advertised from the beginning as containing a bonus character/mission, but we were not at liberty to provide the details. The Prothean is optional content that is certainly designed to appeal to long-time fans, which is why he is part of the CE offering (the version many fans would be likely to purchase). Mass Effect 3 is a complete – and a huge game - right out of the box.

- The content in “From Ashes” was developed by a separate team (after the core game was finished) and not completed until well after the main game went into certification.

- The Collectors Edition has been sold out in most places for some time now, and is becoming very hard to find (many players prefer not to purchase the digital version). As such, we wanted to make this content available so that SE buyers could also incorporate the Prothean into their game.

We’ll be releasing some images and video about this pack in the coming days.

As always, we are extremely thankful for all of your support. We pulled out all of the stops to make Mass Effect 3 the best game ever, and we can't wait for you all to experience it.
