Shoot hats:
Switch to any weapon (I suggest using a pistol). Get a clear shot at an enemy's head. Instead of shooting their head, shoot their hat. It will fly off.

DK in Dam:
Head to the end of the first mission, Dam. Go to the bungee platform that you would usually jump from to end the mission. Instead of jumping, stand on the platform and look to the left and down into the dam. On the side of the mountain is a clear image of Donkey Kong's head. If you want a closer look, bring a sniper rifle with you.

Beat Aztec quick and easy:
To complete Aztec, you normally need to beat Jaws, get the key card he drops, and head back across the level so that you can get into the locked room. To open this locked door without beating Jaws, simply stand at the glass door and shoot it to attract attention. When you see the door next to you start to open, run and hide behind one of the shelfs in the room. One of the guards should go to where you were standing, and open the door to go looking for you. Charge at him and get into the locked door before it closes.

Fire weapon in ending cutscene:
Before you complete a mission, set your control style to either 2.3 (Domino) or 2.4 (Goodhead), and equip the weapon you want to fire. If Bond is holding a weapon in the ending cutscene, you can fire the weapon and kill the people surrounding you by pressing Z on the 2nd controller.

How to mix and match guns:
EASILY To mix and match guns easily do the following:

1. Put the all weapons cheat on and "x2" cheat on
2.go to a double weapon (where you have two of the same weapon)
3.press A as to go to the next weapon, but instead of following through just before it gets to the next weapon press Z so it goes back to the last weapon. While it is switching between guns release Z and then press Z.
4.The effect this should have is the effect of one gun in one hand and a different gun in another hand.

Suspend ammo in the air:
In the bunker level, if you go into the big room and look up, you will see monitors on the ceiling. Plant some remote mines on them and blow them up. Now you can fire rockets, grenades, tank ammo, or anything that is not a bullet and it will suspend in the air. It works best if you move backwards as you fire. The ammo is live so you can pick it up again or shoot it with a gun and it will explode. You can suspend the ammo anywhere in the level. It can be done in both single player and multi player modes.

Refill your Rocket Launcher even when there's no rocket ammo around:
When you're out of ammo in your rocket launcher, hold down Z and look for any big gun ammo (like the RCP-90) and pick it up. It will refill your rockets!

Jump back up into ceiling in Facility:
In order to get back into the beginning vent in the ceiling in the Facility level:

1. Stand on top of toilet in the stall directly under the hole in the ceiling.
2. Hold R and Right C
3. Hold Left on the control stick.

This should make you spin around counter clockwise on top of the toilet. After about one or two turns, you will suddenly launch into the vent. Make sure you quickly hit down on the control stick so that you back up into the vent and don't fall down again. This is useful in Multiplayer Mode.
