This guy lists all 99 achievements for the not even released Orange Box.

Considering the length of the game (HL2, plus EP1 and EP2), this was probably expected. Still, AchievementJunkie is going to have a field day :D

Most of the Achievements are for HL2 and TF2 but I still cannot wait for this bundle of bundles.
