xboxx one BC mass effect 2

I dont think so as the disc will turn into a digital copy one the xbox one

Ummm I don't think Mass Effect 2 & 3 won't get BC since both of these games come with more than one disc.

BC will not work for Kinect games & games that come with 2 or more discs.

Mass Effect 2 and 3 are only available to the BC program as a disc version. There is no digital version available for download.

Battlefield Bad Company (1&2), the campaigns are so much fun. There a ton of great games in the BC list, like Mass Effect or KOTOR to name my other favourites, but Bad Company was the one I expected the most and I played it on day one when it became
BC.
