ok, this is ocming from the offical strategy guide in my own words...

when you are looking at the turrets in their cases or when you havent grabbed them yet, you want to put them to your right. to your right, there is another hall way, and to the right again there is a door. but one turret facing the door, another one directly behind it, and one more facing the little hallway where you picked them up. next, stay right next to them and MAKE SURE NONE FALL DOWN. if any fall, your chances of winning drops by like 50%.

this will last for 6 minutes. pretty much keep your g-gun up all the time to grab the turrets ift hey fall. if they fall, get them up within 2 seconds.

also, the grenades taht they throw you can grab with the g-gun and throw them back at them. that helps so much when i tried it.

gl to you.
