What is the hidden achievement I missing? (it's the last one giving 10G).
I checked with the list and didn't find the one marked secret.
It's one which give 10G, and the only ones that give 10G in this game are the story-related one that can't be missed, except the Patriot one and I got this one.
Edit : Found it, it's the "It's not worth it" (which can also be missed), but weird, I didn't killed Lenny, I just subdued him. Guess the game don't take that in account and want you to not touch him at all.
