GoldenEye 007/Cheats

Upon activating the first cheat you find, on the menu where you select single- or multi-player mode, there will be a new option. "Cheat Menu", at the bottom of the screen. Click on it to bring up a list of all the cheat codes you have discovered. Click on the name of the cheat to toggle it on and off.

On single-player mode, if you have a cheat activated, you can only play levels that you have beaten, and on the difficulty level(s) that you beat them on. For example, let's say you've beaten Dam on Agent and Secret Agent. When you have a cheat activated, you may play Dam on Agent and Secret Agent ONLY. If you want to use that cheat to help you beat it on 00 Agent level, tough.

Some cheats only work in multi-player mode (like the "Turn off radar" cheat), and some only work in single player mode (like the "Enemy rockets" cheat [which really isn't a cheat, but I'll get into that later]). If you use a multi-player cheat in single player mode or vice-versa, it won't really make a difference, aside from the fact that you're still unable to play an unbeaten level with it activated for some reason. Probably a bug.

Time cheats
These are cheats that are activated by beating the game on certain difficulty levels in a certain amount of time. Once you beat a level within the allotted time (listed as the "Target time" on the screen where it tells you your accuracy in the mission, what objectives you accomplished, etcetera), the cheat will be added to your cheat menu. You'll know you've acquired the cheat when A) Your completed time in the mission is lower than the Target time, B) The words "NEW CHEAT ACTIVATED!" show up in capital red letters next to your time, and C) You hear a loud cymbal-like sound. Not very obvious, is it? ;)

Agent

 * This gun is not the actual Golden Gun that you find in multiplayer mode. The cheat to get that gun is beating Egypt in any time.

Secret Agent

 * The first one, not the one at dusk.

00 Agent

 * The first one, not the one where you have to break out of the jail cell.
