Hints and tip for Perfect Dark

In Carrington Institute: Defence, you can stop a small flow of guards. There are several areas where you can stop guards. When you obtain the devastator from Hacker Central, or using an explosive gun by cheating, go to any of numerous areas in the downstairs corridors (where you activate the sentry guns) and in four areas you can stop the flow of guards.

By sentry gun #3, The one far away from the hangar, go towards the pad. Face the pad straight, then go left through the doors and go right down a long hallway. Go through those doors and go into the small box-like room.

As soon as you enter, look left. Shoot an Explosive at the corner. If you stand back to watch, you can see a guard fly out. That now indicates that guards will stop coming from that area. Now go towards the Sentry gun near the upper exit of the hangar. In the area by the doors (if you follow the hallway) there is a spot where you can shoot. You might as well just keep shooting where ever because it is very difficult to explain.

Now go towards the other Sentry Gun that was not mentioned yet, and go through the first door you come to. Follow that corridor to the far end and go through the double doors. look right and there is an area that is separated by a small wall. Shoot into the corners to the left and right of that and there should be two guards that come out. I must go, but there is one of these in each landing pad, and also one right infront of your office.
