I only have 11 and beat the game on Casual and Hardcore lol. I have had alot of trouble finding them.
I found that after you hear the sound that means all foes are dead, you generally have plenty of time to hunt around and find them. They actually give you a good shot at finding them all. Two exceptions are after the firefight leaving the prison at the beginning (before getting on the copter) and after you kill the first Berserker (***spoiler*** come out the door and it's along the wall on the left, I missed it the first two times). Those two times it goes to cut scenes right after the final kills so be quick.
