To unlock all single player and multi-player levels in GoldenEye: Rogue Agent enter DOWN, RIGHT, DOWN, RIGHT, UP, DOWN, UP, LEFT at the extras menu.

Press Down, Left, Up, Left, Right, Down, Left, Up at the extras menu.

Go to the bottom part, then kill everyone. Next, go to the steps were you started and go to the lump in the ground. Take out your Q Spider and go in the hole. Follow the path to the lift and get it to go up. Then, go to the next hole and blow up the thing at the bottom of the wall. You will then be able to get 007 to enter the door.

When you have a Harpoon and are trying to kill someone else with it, shoot the ground around their feet. This is much easier then trying to shoot the person's body. You may even kill more than one. Do not try this with other weapons such as pistols, machine guns, commandos.

When your opponent uses his or her shield, hit them with your stun power. They will be unable to hack out of it because their shield drains all of their power. Then, pick them up and throw them. When your opponent uses MRI Vision, use your shield. You will become invisible to them. Try different combinations of weapons to see which works best for your fighting style.

Use the following trick when you are trying to kill an opponent with a name above their head. When you spot one of them, go for them before you try to kill anyone else, they always have a good gun. Kill them with a shotgun or strong gun. Pick up their gun, then go around killing their other teammates.

Press Right, Left, Right, Left, Down, Down, Up(2) at the extras menu.

At the end of a level, you see your score and these symbols that come up at the bottom of the screen. They are called Octopi. You can have up to five Octopi. You can unlock different things depending on how many you got on a certain level. In order to get Octopi, you must get enough points from beating the level.
