So I confirmed with my own eyes that there are zero achievements for completing all the Terrorist Hunts in single player mode. That means starting up a splitscreen solo and playing with half a screen, as if it wasn't tricky enough :p
Anyway, my biggest problem is how enemies "pop in" and have this knack for coming up from behind at the worst possible moment. I guess what's realy happening is a cluster of enemies will spawn in and during the initial exchange of fire, 1 or 2 units from the rear, maybe hidden from view, will start circling around your position. By the time you've mopped up the unlucky men up front and think you've "cleared" a room, the stragglers have found position behind you. So begins the rather nail-biting routine was moving foward, clearing in front, turning around, clearing your rear, then move forward again, clear front, clear back.... and so on and so forth.
Fun stuff, but intensely frustrating when you expertly flush out a mob only to have that one guy who walked in from 4 rooms away to take you out with a few pistol shots.
