Ok... In the Beta, I was playing the main questline on a mission where you had to eliminate all the mutant snipers on the ridge. Everyone had this... "Glitch" I guess we can call it. When the boss grenadier arrives, the audio is just typed into the subtitles to say what it was. But if Trion had the time to finish the audio in the later quests, why didn't the audio for this show up? (Not meant for a hate message.)
