Mass Effect has put on some weight since we last saw it; Instead of the one disc that the first game shipped with, both the Xbox 360 and PC versions of Mass Effect 2 will come with two. Or three if you decide to get the Collector’s Edition, that final one holding ‘making of’ and other bonus materials.

BioWare’s reasoning is a simple and, considering what we’ve seen of the game thus far, an easily acceptable one. “Because you cannot fit this much awesome on one disc,” says community coordinator Chris Priestly who assures that swapping the disc will be a minimal annoyance, “… it occurs at a carefully planned place in the game (that does not interfere with gameplay) and is done once. You do not swap back and forth. 1 swap and then done.”

The PC version does not require disc swapping once the game’s been installed.
