Enter The Matrix

Playing as Ghost on the city rooftops, after evading the many gaps and climbing the ladders, the Agent that burst through the door drops down to destroy you. If you choose to hide behind the left wall and attempt to fire off rounds from around the corner at this Agent, he will unsurprisingly dodge every bullet. If you Focus, you should be able to jump over the gap between you and the Agent, and will be able to engage in hand-to-hand combat. However, at this point it is extremely hard to win; so continue to jump across to your left. Fall down into the lower area. Now instead of taking the cop out and running up the stairs, dispatch the cop(s), but wait around long enough to see the Agent. If he fires at you, then Focus and bullet dodge to get close to him. You now have enough space to fully challenge this Agent without being closed in. Battling an Agent is more intense (and difficult) than taking on any groups of police or SWATs, because they can avoid all bullets and have shattering strength. You will have to Focus almost all of the time in order to knock him down, and inevitably you will soon find yourself on the brink of death. Run up the stairs and to the phone if low on health. Note: Although you cannot fully destroy the Agent, you can temporarily defeat one until it moves into another body. This would seem impossible, but there is a way. Going back to the point where you climb up the ladder and the Agent first drops down, instead of waiting for the Agent to land, climb up the ladder. Before you even see the Agent, start running and use your Focus to jump to the platform where the Agent lands. Still holding Focus, move behind his position where he lands. Begin to kick him, and as he is off guard, he is very unlikely to counter. If you kick him enough, you should be able to knock him off the edge of the "platform" and down the gap, causing the Agent to plummet to his death. Thus, you have temporarily defeated an Agent. Note: If you should ever face Agent Smith, you would be wise not to underestimate him, he is the most skilled Agent.

Press Focus, then Down + Kick to trip the Agent. Immediately when he gets up, press Kick and he will fall off the edge and stay out of your way for awhile.

It is possible to beat the Agent who comes through the ceiling to death. Enable the "Unlimited health" and "Unlimited Focus" codes and it should work. Note: This takes a very long time.

When you are running from rooftop to rooftop, you will see an Agent drop down onto another roof across a gap. If you Focus and unload on him while running at him, he will begin dodging your shots. Jump across the gap and over the Agent, firing at him as much as possible. When you are over his head, stop Focusing. You will land behind him and although you will not be shooting at him anymore, he will still be dodging for a few seconds. Use this opportunity to get in a good strong kick or try to knock him into the gap. If you do not get him in the gap on your first try, you should probably quit. If you knock him off the roof, you will see his gun appear on the ground, then quickly shrink into nothingness. You have now defeated the Agent.

This is very difficult to do and may take some time. After you see the first Agent, keep running as usual. When you reach the place where the agent jumps through the wooden roof, shoot at him to keep him occupied (or throw him in Focus mode). Run up the steps quickly and let him follow you. When he runs at you, move out of his way and let him stand near the edge. Run up to him (not in Focus) and try to throw him. Eventually, he will fall off the edge. When he does, stand on the edge on one of the little "bars". When you look down, you will see Agent Smith laying down on the sidewalk with his gun beside him. Note: When you look down there, you will also see regular cops shooting at you.

When driving as Niobe or riding shotgun as Ghost, you can avoid being shot at. To do so, keep your screen in front of you. Doing this makes your enemies seem as if they are not there. They will stop shooting as long as you do not shoot at them.

To do this, it is best to use the "Unlimited health", "Unlimited ammunition" , and "Unlimited Focus" codes. Use Focus and try to disarm the Agent. It may take a while, but eventually you should get it. Once the Agent is broken, you can punch and kick him and he will not react. He will just stand there and straighten his tie every once in a while. If you try to shoot him, he still dodges the bullets as normal.

If two or more weapons are available, press Left or Right. This should cycle through your weapons.

If you activated the "TRINITY" folder, type HANDSHAKE.EXE and press Enter. You will see a message from Spark. Type anything and press Enter. He will say that you sent him a file to download with a trojan virus. He will then say that he was playing. He will tell you something about you having access to his computer. Access the "DIR: folder and go to "LOGOS:". Go to your command list and select "EMP: in what he gave you. He will say that he was just kidding and will give you a gift in the loading screen. When he is done, you will hear a message from Neo. He will then say goodbye and shutdown the computer for you.

When the "Unlimited Focus", "Unlimited Health", "Unlimited Ammunition", and "Maximum Firepower" are enabled at the same time, the game places a grenade or bomb immediately where you begin the level (only on some levels). It does not kill you, but will knock you for a loop. For example, on the "Agent On Board" level, you start out besides Axel. If one of those cheats are enabled, the bomb will blow up Axel and you will die, ending the game. You must play this level without cheats in order to complete it. The way to get away from the bomb is run before it explodes.

Enabling cheats can also cause other undesirable effects in the game. For example, when fighting Agent on Board and trying to knock him off the plane, he will carry an MP5 instead of being unarmed.

When using codes such as "Unlimited Health and "Unlimited Ammunition" on the Catching A Plane level, when the last intermission sequence is loading the game may exit.

Using the "Unlimited Ammunition" code on the Water Way level will prevent you from getting the flashlight.

Enabling too many codes in the Airport level may freeze the game at the end. When you get close to the end of the level, a loading screen will appear and turn black. You will have to reset the game to continue.

No cheats can be enabled when attempting to load the mission named "Malachi And Bane 2". The screen will turn black and the game will freeze. If codes are enabled you must reset the game and replay the "Malachi And Bane" mission in order to continue. After the level is completed, you will be able to save.

As Niobe, when you first start a woman runs past you. Run directly towards the railing and jump over it. Sparks will tell you to stay out of the lobby unless you want a fight. Fight the cops that enter the lobby then turn and go back to the side of the concourse that you started on. You must stay on the ground floor and run towards the escalators. Turn left when you get to them and do not go up. Continue across to the other side of the concourse and turn left around that corner. Somewhere in front of you or near you should be a man. If you go near him, he will start to run away. Follow him. He will keep looking back at you and will trip. He will run slightly farther, then stop, turn, and walk out the door of the terminal. You can follow him out before the door closes to get outside. You will see the SWAT van parked at the curb, and if you go around to the other side you can pick up an entry shotgun. There is really nothing else useful out there, but you can run around if desired.
