They don't change where they are pointing animation-wise. However, the flak trajectory is slightly cheated up or down depending on the player. I suppose I could have said point-of-impact rather than point-of-aim
Best way to see it in action is to assign the following script (modified from a mock ally script by xplosys) to an enemy, give them a flat trajectory flak weapon and stand behind them. Note that they shoot straight but if you crouch they shoot towards the ground.
