Tomb Raider

This is one of the hidden achievements and one that can't be completed after finishing the game, so try to finish it during the first playthrough. During the game, you'll meet some of the Endurance crew members. You can talk to them by going near them and pressing "E". You'll notice text cloud symbol above their heads as long as there is an option to talk to them (repeat the talking until text cloud is gone and than move to another character). Conversations are saved on next checkpoint so, if you die before you pass the checkpoint, you'll have to do the conversations again.

Here are the characters you need to talk to in order of appereance in game:

1. Whitman
2. Roth
3. Roth
4. Jonah, Reyes, Sam
5. Jonah, Reyes, Sam, Whitman
6. Jonah, Reyes, Whitman

This achievement doesn't require the Whitman conversations. You can still go for them if it makes you feel better (might as well), but if you missed just those two, you should be totally fine. They're still listed above just in case you want to see them.
