In Sleeping Dogs, which DLC do I need to do all achievements?
Sleeping Dogs have only two expansion packs (so far) that give you achievements:
- Year of the Snake
- Nightmare in North Point
trueachievements.com is usually a good website for all your achievement needs. Here is the link to the game page on the site. Scroll down for names of achievement-enabled DLCs.
