I am currently missing Audio Log #2 for AWU General Secretary Joe Chen, and I am wondering if anyone has a proven method of getting this missing piece. No I am not lvl 20 yet, BUT I have been steadily collecting audio logs without leveling, so I find it hard to believe thats the case. Also, I have finished both factions campaign missions on hard including the "What-If" missions. Any help would be greatly appreciated folks.

I think it is just from XP gained - when my first char. reached at 20 I didn't have all the logs but as I leveled up my second I unlocked the rest (I can't remember if I unlocked any while playing at lvl 20 on my original char. or not).

I thought it was for every mission you won! am i right?
i've beat a mission with no bots, just me and i only got about 100xp and i still got an audio log

If you've beaten all missions on both sides you should have it. I think there are one or two that unlock from challenges, but I'm not sure.

...and you have to play the campaign on 'hard' respectively 'versus'.
