Would you be willing to answer a few brief questions about PlayStation Forums?
In solo mode, there's a problem with synchronization of french voices (EUR version of the game). I don't know if it's also present in the U.S. version.
I have installed all the updates, but it seems that bug has not been fixed so far.
Here are some youtube links from various walkthrough that show where this bug is:
Can we hope that this bug will be fixed in a future update patch?
Could you forward this message to the technical team of Naughty Dog, please?
And thank you so much for this amazing game!
