Xbox 360 Achievements has the full list of Mass Effect 2 achievements. None are secret achievements, which means you should take the spoiler alert here seriously.


Looking through it, I don't see any plot giveaways, although "Cat's in the Cradle" might raise some interesting questions of a character's parentage. Then again, I could be reading too much into that.

Here's the full list, 50 in all for the maximum 1,000 gamerscore. The link at the bottom has the achievement icons.
