I read in several places, wikis, forums etc. that you only need to break into one of all the black markets to trigger that achievement. I broke into the last three, but the achievement denies to get activated. I mean, I even have it on the results table after completing a mission, that as one of the special events during the mission, I broke into a black market. I tried reloading several times on the last black market. I even validated my data files... no effect, no achievement.

I know, that achievements aren't everything ;) I totally love the game itself. It would just be nice to know, if other people have the same problem and maybe know a workaround.

Thanks in advance...

Only "solution" was to use another saveslot in a second playthrough...
