Fixed it...or whatever!
I´ve tried the achievement several times on Interval 6 but with level select!
Also in the last interval on the ghosts...no Cheevo -,-
Now im going to the campaign, collecting all the intels and stuff and when i´m in Interval 6 again, i re-tried my Slow Jo achievement and got it on 2nd try!
May it just unlock on instant mission or campaign!
Why my english sucks?
Because its not my Mother Tongue
On some posts I think people don´t buy Games, they buy Achievements
