Firing Range Trick
Here's a handy little trick if you're having problems beating all the weapons challenges in the firing range. Go into the Carrington Institute firing range and access the Laptop Gun challenge (for any medal). When the training session begins hold down the B button so the gun switches over to the secondary weapon mode (sentry gun). Hit Z to deploy the sentry gun -- but as soon as you hit Z hit the START button. Select "abort", then hit START again as soon as the screen starts to fade. You should now be back at the weapon challenges list. You can now pick any challenge you haven't completed and commence the training. If done properly, the sentry gun should still be deployed and will start firing at the targets and beat most of the challenges for you. Note that there are some challenges where this trick doesn't work, such as the RCP-120.

Cheese List
Why are there pieces of cheese hidden in Perfect Dark? Well... The guys who made this game are from England, and... Ah, hell. We don't know. But here are the cheese locations:

1.1: Enter the first big room, with the big ventilation fan, the light switch and the security hub. Just to the right of the security hub is a large gray cylinder, hit the cylinder with some type of explosive. A large hole will open up, enter the hole and you will fall to a small room with 3 vents and a ladder. Inside one of the vents you will find the cheese. --Goskins18@hotmail.com
1.2: The cheese in the dataDyne research lab is on the pipes below the glass floor in the lab where the bastard scientist sounds the alarm on you. The glass I'm talking about is forward and below from the entrance to that particular lab. At least I think it's cheese.... --`Xenocide
1.3: On mission 1.3, you can kill a guard to get the keycard [see walkthrough for instructions on how to get this key card] to Cassandra's office. She isn't there this time, but there's a grenade on her table. If you throw it in the right hand corner of the room, one of the walls breaks away. Inside you'll find a Dragon and... a piece of cheese! --BennyBoy32
2: After activating the wind generator, continue through the underground passages towards Carrington. After going down a set of steps you'll soon end up in the wine cellar. The first room has two shelves of bottles, but no cheese. Proceed through this room to the narrow hall. Jackpot. You are in a small, narrow hall with a shelf of wine bottles on the left and one further down on the right. The left one has a small piece of stinky yellowy-orange (with darkish looking holes) cheese on top. It's pretty much in the middle on top, and it's kinda hard to see. Once you've located a spec of yellow, use the sniper rifle to zoom in and inspect your prize. It's unmistakable -- that's cheese. --Dallas Gow
3.1: In a toilet in the Punk Pond bar. [see walkthrough for route into Pond Punk] --Billy Collister
3.2: In the vent in the Damping Control room. Behold the power of cheese. --Mr. Squishy
4.1: Not discovered yet.
4.2: In level 4.2, it helps if you have a sniper rifle [cheat]. You have to do it on the difficulty special agent or higher. Blast through the wall and head down to the locker rooms. Go through the door in the middle and kill all the guys there. Go up the ramp across from the door. Then you get to the t-section you should see a section of railing in front of you just to the right. Kneel down and pull out the sniper rifle and look straight ahead down the vent shaft and you will see the cheese. You can walk across the piping and go into the vent shaft but if you go too far you'll fall into the locker room. --pranger
4.3: On escape from area 51,on special agent play the level normally,cross the zig-zag bridge that spans across the gorge and make your way through the next room (where johnathon is on agent difficulty)when you come to the next door,just keep heading straight through the series of doors ahead of you until you come across a big room with catwalks and support rails heading off into the left on the first one there is a break in the rail that you can walk out on the rail to a little vent..duck,zoom in with the sniper rifle..and theres that sweet cheddar!!! --michael rice, aka devoid
5.1: Go through the caves where you sedate the stewardess and head to the left of the cable line all the way against the mountain. Pull out your slipery sniper rifle and point and zoom it at the water where the arrowshaped mountain seems to indicate. Swiss cheese it is my fiends. --duros bith
5.2: The cheese on the level where you are on Air Force One is on some equipment near where the presidential escape pod is. --Andrew
5.3: If you go to the right side of air force 1 on the crash site level and look through the crevice on the right side of the wall guarded by one of those "Scandanavian Freaks", you'll see a little speck of yellow. Upon further inspection (with the sniper rifle) it is quite apparent that you are looking at a block of cheese!!! You can't get to it because of an invisible wall, so you may have trouble finding a good viewing angle. --Found by Brandon Whaley aka Red Picasso, redpicasso@ignmail.com
6.1: Say goodbye to Elvis and proceed through the first door. Turn right and go down the hall. Left at the alarm and through the door. There should be a sort of pillar in this smallish area. Keep going a bit and there will be a door on the left. The door leads to the room with the big power thingy (where you have to use the XRayScan to hit switches). Don't go through the door, but instead walk forward a bit. There will be a large grate in the floor. Shoot out the lights on the floor if they're too bright, and look down. There's a big stinking wedge of fromage down there. It's pretty obvious and unmistakable -- that's cheese. --Dallas Gow
6.2: I found a hidden cheese today while playing my brand new copy of Perfect Dark... In Mission 6.2 (Deep Sea- Nullify Threat) right at the beginning of the level if you look to your right and out the windows that look into the ocean floor, you can catch a glimpse of a piece of cheese near the far back wall of rock. You can get an even better look if you go through the first door straight ahead and look to your right again. It just jumped out at me and I couldn't resist getting on the IGN Cheese List. --Jason Kiernan
7: Shoot the Skedar at the beginning, then go through the door right next to him. You'll be on a balcony overlooking a landing pad. Directly to your right you'll see a small ramp leading to a shiny door. Go up the ramp, against the door, and turn around. Above the door you just came through and slightly to the left, you should be able to see the cheese in a narrow crack. Just follow your nose; that cheese has been in the sun for awhile. --donor
8: This piece of cheese is easily found. Take the elevator down into the Skedar hangar (with or without Elvis) and turn right after the ramp as you enter the hangar. Head back towards the elevators on the wall in front of you and go into the room on your right. As you enter the room, turn left, crouch and look into the hole in the glass portion of the floor. In the back left corner is a lovely piece of Swiss cheese. --Found by Chris Flyer
9: Next to the Shield (only there in A/SA) at the end of dead end tunnel (head the WRONG way at the start). --Billy Collister
