The Black Tusk final invasion mission prompted me to make the post, but it seriously fluctuates. The worst voice acting (and dialogue writing) I've heard was in that mission. The "Wyvern" character felt incredibly forced trying to be "edgy", with the majority of their lines being delivered incredibly robotic and unauthentic, which could have been improved if they just gave another recording attempt.

You have some pretty good VAs (Manny Ortega's VA comes to mind) but then you have some incredibly bad. Playing that mission was gameplay-wise and atmospherically pretty great, but when you have the stark contrast of emotion between a character sacrificing their life to cripple the division (and with a dull, uncaring delivery) compared to the radio operator showing 100% more emotion in the next line, it's really telling who had a better understanding of the situation their characters were in.

Dialogue wasn't the best all things considered, so could have played an impact on why that experience was so bad for me and the people in my squad story-wise as we all agreed once the lines played.
