I have gone over the list of all the creatures on PSP1 and comparing it to my list. I have checked it over and over again and I dont have the kill all enemies achievment even though all the monsters were covered on my list and the psupedia list. Is there a monster that is not on the list on psupedia?

The only thing that i can come up with is that maybe you have to finish the mission to get credit? When I finally got 3 people to get to that one monster, I quit the mission after getting the kill. So maybe that could be the reason?

Anyone have any idea of any monster that I dont have? Or any reason any of my monster kills were not "counted"?
