Until there's an official statement, this is slapped with a rumor tag, but one of our Destructoid Community Bloggers has seemingly discovered that his videogame store will be receiving copies of BioWare's Mass Effect for PC.
The discovery came from an EA newsletter which arrived at the store where Dtoider myaimistrue works. It lists the game as MASS EFFECT PC DVD 5030945065685 EAN07706226 TBC TBC ACTION 18+ 25 SWE ENG. Complying with one of the cardinal rules of the Internet (pics or it didn't happen), he also provided a shot of the newsletter itself, which can be viewed below.
This isn't very hard to imagine being true, since a game like Mass Effect should be quite comfortable with PC controls, if only because the 360 control mapping was bloody awful (once again, the back button threw grenades and there were three buttons to draw your weapon). A good few gamers wanted to see this come to their computers and now it looks like it'll be happening.
Destructoid will keep you mouse n' keyboarders posted when there's more news to go on.
