Halo CE Multiplayer Health hack?

Hello everyone, I was recently playing on the HPTFORUM halo ce servers and there was a guy named "Trolly"
He was invincible, i checked his score and his kd was like 150-0, so he never died and when he had the flag i just kept shooting at him and throwing my frags and he would never die.

Like all of blue team was shooting at this guy and he never died. So i got the rocket and shot but he didn't die either same thing with all the vechiles. I used the warthog but he just didn't die.

Does anyone know any working multiplayer hacks? I need a health hack that makes me invincible in a multiplayer game not my own hosted game though.

Can anyone help me?

Server commands enable godmode
There is also a devmode code that can be used server side...
it has to do with the fact that the player doesnt suffer from any damage effects...
