Mass Effect 2 is different for everyone. BioWare have built a system into the game which reads your save game (if one exists) from the previous Mass Effect and tailors your experience of the sequel based on that. On top of the way your story begins there are various different ways to play the game and various branches throughout the storyline which will all have an effect on how the story concludes for you.
But that is getting ahead of ourselves. There will be a “First Level” feature on TSA soon and you can expect a full review next week, when I’ve had a chance to put some time into it. For now, I’ve captured my own opening cinematic sequence which is based on the choices I made in the first game. Enjoy!
