jeremyh120 Posted August 18, 2011 Share Posted August 18, 2011 I just finished the game today and unlocked everything else besides this one. I did have to go back for nitro splicers but I did end up finding one but PhD never unlocked? I know for a fact I have all 3 bots. (camera turret and flying) Is this a common problem?

McGoogles Posted August 19, 2011 Share Posted August 19, 2011 No, it should've unlocked once you've fully researched your last subject. Maybe you fully researched something and got the achievement but your Xbox 360 froze and you completely forgot? Try loading an earlier save and researching everything from there to see if you accidentally forgot something. Link to comment Share on other sites More sharing options...
jeremyh120 Posted August 20, 2011 Author Share Posted August 20, 2011 I think I'm just unlucky. I know nothing like that happened because I was also going for no vita chambers. I have read a few posts on here about this happening and one guy even said it randomly unlocked while he was just running around snapping pictures of nothing. So I may try that, but ultimately I'll probably have to do a quick run through again to see if it will unlock. At least the audio dairy one unlocked... that would have taken forever to re-do. Staying optimistic, ha. Link to comment Share on other sites More sharing options...
Mattiixk Posted August 31, 2011 Share Posted August 31, 2011 Had the same problem during my playthrough! When I decide to replay it I'ma go on my last save and have a go at backtracking to see if I did in fact miss any. Link to comment Share on other sites More sharing options...
warborn718 Posted August 24, 2012 Share Posted August 24, 2012 You might have completed the research on one of them, got the achievement, then died later without saving after you maxed out that particular research. I almost did this but i realized it before it was too late, so go back and take pictures of each of them again and you'll know if this is the case.
