i hope mass effect 2 shows you what you have done in your previous beaten files because i have...a lot...
and i am currently working on my "perfect" file to be in use with me2, level 60 soldier with lift, specter x weapon, collosus x heavy armor (which i have not yet seen for humans), just about every quest complete, full paragon, ect.
but if me2 lacks such a feature, im going to have a hell of a time finding the "right" file to continue off from(seriously, i got like 15), even though its probably going to only minorly effect the game.
