I don't know if anyone has the same problem, but for some strange reason, que game gives me a CTD everytime I try to collect the trophy belt in the research lab in the predator campaign. The one right above the train, in a catwalk, in the big room as you enter the lab. I don't get any kind of message. It looks like the game just closes.
I just found this crash as this was my first time trying to get the collectables. Already finished the game multiple times and never had a single problem.
Do you guys thing that the problem could be with steam itself instead of the game? Since the problem appears to be related to the achievement.
