Yeah this bug is repetitive with my game, I was enjoying the campaign for about 2-3 hours

it got that interesting XD. But what made me stop was the fact that this mission, Semper Fi or Die, has an annoying bug where your companions in Delta Squad (I think), have a audio bug. They keep repeating "Move up!" all the way through, I could not focus and the aliens soon killed me because the sound was so annoying, also I could not hear what Hargreave was saying in the suit radio.
Summing it down, I have an audio bug which I have no idea how to fix and I will not play anymore of the campaign until this is fixed. I will get you video feed if it's required.
