Hidden FMV sequence
Allow the game to idle at the title screen. You will see a FMV sequence showing a man playing the game.
Every time you engage in a swordfight, use only the hammer or little scorpion moves. These are easy to pull off, and will give you respect each time they hit. If your opponent is dodging these attracts, which some do, then hit him or her a few times with another attack to bring him or her to about half health. Then , attack away. The opponent might block your attack, but it is very powerful and will break their sword after a few hits. Note: This does not work for every fight. For example, against Harry as his sword is unbreakable. Also, it will not work if you do not have an offhand sword equipped.
Never kill an opponent after a duel. If you let them live, you will get a lot of respect, and they often open up secrets for you.
As soon as you learn how to focus, start to use it. When in combat, focus as soon as you can and shoot the guns out of your opponent's hands (aim inside the white box). Then, shake the Wiimote Up and Down to disarm them. This will take them out of combat and give you about 50 respect per enemy. Also, if there is a leader in the room (an enemy with a circle above his head), disarm him immediately to make all other enemies in the room disarm, giving you a huge respect bonus.
To increase your focus quickly to disarm opponents, use the Uzi. It fires a lot of bullets that do not do a lot of damage. Therefore, if you are out of focus and want to disarm someone, shoot them with the Uzi for awhile. You should get enough focus back to disarm them without killing them. Try doing this if a leader comes in the room and you are out of focus. It makes tough rooms a much easier.
Break opponent's sword
When your opponent starts blocking your attacks in a sword battle, use special attacks to break their sword.
Locate the geishas on the mission assigned by Reiko. Look at the nearby lockers and open the one with the darker door. Inside are photos of the development team with blonde wigs.
Shoot an Uzi at nothing for a long time and the game will freeze.
In multi-player mode, if your opponent(s) are dead and you scope with the sniper, the crosshairs will not be in the correct location.
Casino: Easy access from exploding bunnies
In the casino level where you need to "play with the bunnies and hunters", you will reach a point where you need to advance up a snowy hill via penguin lift. The easiest and safest way up by climbing the downward moving track towards the left side of the arena. Simply jump on the track and move to the right of it. The entire left side of the track will move you down, however a tiny bit of the right side is motionless. You may not be able to see it because it is a glitch, but it will allow you to reach your destination quicker and out of reach from snipers.
Restaurant: Leave level boundary
In the Restaurant stage in Multi-player mode, go to the platform where the sniper rifle (AE Rifle) is located. Jump onto the wall next to the stairs. Then, jump out into the sky outside of the course. You will land on a green clump of land. You can move through the green mass on solid land, but if you throw a grenade it will fall through the floor. The only way to exit is to have another player kill you.
