Mass Effect 2 is the first game in the series to appear on a PlayStation console and it was released almost a year after the versions for other platforms. The game comes on a single Blu-ray and has additional, previously released content included on the disc.
The included DLC packs introduce new missions, an expanded storyline, and new vehicles, weapons and items. Next to a tweaked engine for more graphical polish, there is an additional introduction. Players of the original Mass Effect could carry over a number of choices from the first title using a savegame. These involve events such as a romantic interest, a sacrifice near the end of the game, the main character's appearance and the statistics that had been built up. To resolve that and to bring PS3 owners up to speed with the storyline of the original game, a new chapter called Genesis was added. After determining the gender and look for Commander Shepard and playing the main introduction, Genesis is accessed. It is presented as an interactive comic where players get to relive the events of the first game and also determine the six major decisions that are carried over to the second game.
