Enter the Matrix Cheats

First, unlimited ammo code helps a lot here. First, choose an automatic
gum like ump or g29 that have a large clip. Start shooting so hell stay
still and dodge. While he's dodging run backwards and throw grenades at
him till he dies. that-a-way you kill him and get a pretty good pistol.

It is possible to take down Agent Smith without a wall kick, even if temporarily. First, scoot back so he does not throw you, then equip any gun and fire. At the same time, go into Focus and while he is dodging the bullets you just fired, run in then punch or kick him until he goes down. Kicks are recommended because they are more powerful. Then, get out of there while still using Focus. When you are out of harms way, let off the Focus. Note: Doing this in cramped spaces such as hallways is not recommended unless absolutely necessary.

Hey people you must go to the hacking icon and enter cheat.exe before you enter your cheat then before each cheat type in cheat space and then the cheat these cheats work because I have tried them myself

P.S: you cannot get neo or trinity so don't try it is all bull.

In certain levels you have grenades or grenade launchers.
Three launched at far range or one at close range will kill them.
If they do not die, pull out a gun. When the auto aim is red,
it indicates near death; you can easily take them in hand to hand
combat. Sometimes sparking objects are nearby. Knock them into
it and will die.
On the level where the Agents chase you up the stairs and onto
the rooftops, you can kill them. Before entering the levels, make
sure you have enabled the "Unlimited ammunition", "Unlimited
health", and "All weapons" codes.. At the beginning
of the level, cycle through your weapons and select the grenade
launcher. As soon as an Agent runs after you, shoot him three
times with the grenade launcher. Wait until the smoke clears and
they will be dead.
This trick works best if you are Ghost. In any level that has
an Agent and you are or can get to a roof, go up to the Agent.
He may kick or punch you back; watch the ledges. Hit him once
or twice so that the camera pans to the side. Walk up to him,
punch him, then do a Focus Kick (without pressing a direction).
The agent will fly back. While he is on the ground press [Punch],
[Punch], [Focus] + [Back] + [Punch].
This will do an uppercut, sending him flying. Once he is in the
air, press [Kick] and Ghost will do a flying kick, sending
the Agent soaring across the room. If you are on a roof, do this
to send him flying over the edge, where he dies on impact.
Enable the "Unlimited ammunition" code and obtain the
GP gun (which takes the oxygen out the air). It can kill an Agent.

I have found a way in which you can play with Neo Trinity Morpheus and more...

1. Firstly you have to open your enter the matrix folder, then open the "actors" folder (make a backup copy called "actors_backup").

2. Then you have to find all the Costumes for the original players...(e.g. "Ghost_Costume01.dcx" or "Niobe_Costume01.dcx").

3. Then find the player you want instead of Niobe or Ghost (e.g. "Neo.dcx") and copy that file to how many costumes there are for each player. (e.g. 5 Ghost Costumes = 5 "Neo.dcx" copies)

4. Then rename all the ".dcx" for the desired player (Neo.dcx) to the original player costumes (ghost_costumes01dcx).

5. So..."Neo.dcx" will be renamed to "Ghost_Costume01.dcx"...and so on...

6. After that load a game or start a new one and you wil be playing with a different player.

***NOTE***
All the characters moves will remain the same...only the skin will be changed.

I have tried the following players and thry have worked for me:
Neo.dcx
Morpheus_coat.dcx
Trinity_zen.dcx
AgentSmith.dcx
AgentThompson.dcx
AgentJackson.dcx
AgentJohnson.dcx
Seraph.dcx
Keymaker.dcx
Sparks.dcx

Enjoy!!!
