Here's some basic codes to 007 Goldeneye:
Navigate the Golden room in Egyptian Temple-When you enter the room with the Golden gun, follow these coordinates on each tile to get in without being blown away by the drone guns...left,left, up,up,right,right,right,up,up,left,up,left,up,up, right.
Easy detonation- to easily detonate remote mines, press A and B at the same time.
Paintbrush Weapon- Play a multiplayer game with sniper rifles. Grab one but don't get ANYTHING else...not even ammo. From here press the A botton 2 times to bring up a paintbrush.
More time on train-On the train, line up at the end so that Xenia is blocked by Ourumov. Use the ZMG and shoot at Ourumov but keep shooting while he falls. You should hit Xenia(don't kill her). She says she's hit, and Alec wont be able to leave without her and wont tell you that you only have a minute until you've almost already escaped!
Floating mines-Go into multiplayer in the bunker and get remote mines. Throw 1 mine on every TV that is hanging from the ceiling in the control room. Blow them up with the detonator and get more mines. Now when you throw a mine nothing will happen but if take a few steps back you'll see a mine floating in midair wherever you walk and lay one!
Maxic Box (Caverns)-Find the radio room. Go around the corner to your right (Left from radio control area) and 1 of the boxes over there is the magic one. If you shoot it, more boxes will keep coming out until you reach 2 computers. Inside these are double assault riffles!
Go back into vents in Facility-stand on the toilet that's under the vent. Then hold Left C until player ducks, press and hold R, and Left on the control stick. When you return to vent, release C & R and press forward on control stick.
