Where can i see what levels i did coop o ...

I thought I went through the whole game on coop, but apparently i didnt.. i only have one act left to do. I skipped the Rookie training in the begining.. do you think I should do that? OR is there any place that I can check which ones i did coop on? Thanks!Where can i see what levels i did coop o ...
You can't check which specific mission you did not do co-op. Just try the training you skipped although I don't think that would be it.Where can i see what levels i did coop o ...
You do have to do the training. The achievement is veryscrewy. For a level to actually count, you have to do the whole level in one shot. You can't do 1-1 and 1-2 another day. You have to do like 1-1 through 1-4 or whichever the numbers are. I did all the levels but I took time inbetween so it didn't count.
This is what i did. I didnt start coop till half way through Act 1. Then I joined an online coop game and we got all the way to the last chapter in Act 5 the Hive. Then i Just split screened the rest of the campain an hour or so later. Then I just went and did the first 3 i missed in the begining.. So your saying I should just complete the whole act 1 in one shot?
Okay nevermind. I guess you DO need to complete the rookie training part.. lol thanks for the help!
