In addition to the core game, it also comes with the premium DLC "Kasumi: Stolen Memory," "Overlord," and "Lair of the Shadow Broker."

Now, one interesting point is that with the lack of Mass Effect on the PlayStation 3, there's simply no way for PlayStation gamers to import a Shepard from the first game. To address the lack of this feature, the PlayStation 3 version of Mass Effect 2 features an interactive comic (in-game) that summarizes the first game and allows players to make the key choices needed to define their Shepard.
While I don't have a PlayStation 3, the interactive comic is already available for viewing online, and you can check it out below.
This comic kicks in after Shepard's "death" at the beginning of Mass Effect 2, and honestly, I'd love for it to find its way to the Xbox 360 version. For someone like me who regrettably lost the majority of his Mass Effect characters, this interactive comic would have come in very, very handy.
