Achievements not working?

[Duskbane]

Where do I go to view my achievements? Might be a noob question but there's nowhere in game as there is in other things like TF2 and L4D.

Select the game in the Steam community tab, should have an option to see the achievements in the game somewhere.

What's not working about them? You can't view them, or you can't earn them?
