Getting this cheat is an is so easy, it's an embarrasment to the game. Feel ashamed if you don't get the cheat the first time you play the level. If you have never held an N64 controller, you should still be able to get it on the first try. I think that the programmer who inputed the target time must have been drunk at the time or something.
Unlike most levels, you can really take your time to beat this one. Forget about strafing, walk backwards the whole time if you feel like it, waste time killing enemies you don't have to kill, you'll always have plenty of extra time. Bond will start in the same building as the facility, take a left and go down the chute. On your left side there will be a small building, in it are two soldiers and a key on the table, take the key (objective a completed) and shoot the soldiers if you want to, then exit. Take a left and head down the runway toward the plane. Along the way, shoot any guards just for fun, a drone gun will start firing at you half way to the plane, just ignore it. Very, very rarely, too much enemy fire hits the plane and it blows up, if it doesn't, just press B when you reach the plane and you're done (objective b completed).
DK Mode
This is most likely the first cheat that you will get in the game, so in the beginning, you will be so happy you got the cheat that you will use it all the time, but once you get bigger, better cheats, You'll use DK Mode less and less. Basically, when DK mode is used, everybody (including Bond) has Donkey Kong body proportions with giant heads and oversized arms that hang down to the ground. They all carry oversized weapons too. Before, I used to think that this cheat was funny, but I got tired of it too quickly. Now I only use it to get a high percentage of head hit in a level.
