BioWare has confirmed that Mass Effect 2 will ship on two game discs when it's released for PC and Xbox 360 early next year.
For PC gamers this simply means a two-disc install, but 360 owners will need to swap discs once during play.
"Even though there is a disc swap, it occurs at a carefully planned place in the game (that does not interfere with gameplay) and is done once," said community co-ordinator Chris Priestly on the game's forum (via Kotaku). "You do not swap back and forth. One swap and then done."
"Why two discs? Answer: Because you cannot fit this much awesome on one disc," he bragged.
The hot space RPG is out on 29th January. Plenty more at the Mass Effect 2 gamepage.
