Goldeneye has many different tricks. I won't bother listing all of the levels and times to get different cheats. That would be stupid, considering how many places you can get them. My Goldeneye Secret Codes link has a list for people who don't have them. Probably the best trick in the entire game is the code where you can get back up in the vent in the Facility. To do this, get in the stall and go all the way until you stand on the toilet. Then press c left until you duck, don't let go of the c button. Then hold r, keep holding that c! The last step is to push left on your control, while still holding the r and c. You will turn around until you pop up into the vent, then you should walk forward before you fall back down. This may take some time to get good at, but it will make you the terror of multiplayer if you can do it fast and efficiently. There is one more thing, this won't work if you are holding a gun with a scope, the zoom will slow your turning, and you won't get into the vent. There are a number of weird things about that vent, but I'll let you figure them out yourselves. There are a few more tricks than I mentioned, but they are not as good. If you still want them, you can find them on the Goldeneye Secret codes link.

I have just recently found a dumb, moronic, retarted, yet strangely appealing trick. Have you ever wanted to climb into the airplane and look around before you take off? Now you can, only you can't take off after you get in. It helps if you have cheats, but it can be done without them. In the Runway, go get the tank (which is to the right once get out of the building). Then blow up all of the drone guns with the tank rocket(Any explosive may be used). Then blow up the missile launcher. Most people have no idea of where the missile launcher is. It is that tall pillar behind the plane. It has a weird thing on the top. That thing on top is the missle launcher. Blow that up. Now you are ready to blow up the plane. The easiest way would be to run it over with the tank. Bullets will now go through the plane. You can walk into the plane, now duck down and check out the cockpit. The plane is not solid, so anything will pass through it. If you do not complete these instructions, the plane will pop into nothingness. This is the most useless trick of all time, but neat and fun.
