Enter the Hacking engine in the game. Enter CHEAT.EXE and the cheat menu will be unlocked. Enter one of the following codes to activate the corresponding effect.

Use the following trick to have one of your multi-player characters carry the sword throughout each battle. Get the sword and then go into multi-player mode. Press Kick + Punch to get the sword out. Defeat your opponent, then when the match restarts you will be holding the sword.

When in the Chinatown level, get to where there is a SWAT team truck and it explodes. Go on the truck that is on fire. You will see that you are jumping and moving slowly. However, it will not make the bullets go slow when the Agents shoot you.

At the beginning of the Big Distraction, instead of going through with the level, walk back behind the staircase at the ground floor. You will notice that instead of an accumulating pile of mail, all the white letters disappear, but the yellow letters will remain.

After activating the two player and the sword fight codes, start a two player game in any level. Let both players kill each other with the sword. If done correctly, you should be able to fight each other with the sword still out.

Use the following glitch to keep the sword out in single player mode. Use the sword, but at the exact moment get hit with a blast. Try throwing a grenade or flashbang, then use the sword on an enemy. You will be thrown back, but the sword should still remain in your hand. Note: You may have to attempt this multiple times in the event you are killed by the grenade.

Go on the Power Plant level (Core Control Room 1). Enable the "Unlimited health" code. Shoot the first three snipers. Defeat the SWAT team that appears in the room that you are in. Shoot all of the next group of snipers, except for one. Go to the far right of the window. Perform a forward dodge bullet move (hold Forward + Action) and you should end up landing on a pole. Go to the highest point of the pole Hold Focus and walk off the right side of the pole. Then, run over to Niobe and shoot the last sniper. Follow Niobe around the brides. Niobe will mysteriously disappear, as well as half the core.

Enable the "Enemies cannot see you" and the "All weapons" codes. When you are on the building tops running to the church, stop just before you get on the board to get into the church. Take out your sniper rifle and zoom in on the church, near the top. If you are playing as Ghost, you will see Niobe at the church, and vice versa

Near the part of the level where you are supposed to answer the phone, take out all the snipers and do a backflip off of the right wall (facing the big fan) of the pillar in the middle, phone story. While falling, press the Analog-stick in the direction of the catwalks. If done correctly, you will land outside of the catwalk, having fallen one story. Look below and you will see nothing. You will not be able to move more than a few steps and never move again. You can only turn, shoot, use Focus (no special moves), fight, and go into first-person view.
