There are a few ways to "glitch" in halo2 ... a glitch is basically a way of cheating depending on what it is.
The 2 most powerful glitches are the "Standby glitch" and the "clone (or) dummy glitch"

1st the "standby glitch"
Check your modem and it will have a standby switch on it ... only NEW modems have this feature.
supposable you have to be the host of the party ..
press it when you are near their flag/base and get to where you want... this freezes up the server (bungie.net) and then press it again ... grab the flag and go back to your base ... everyone else will be playin catchup cuz bungie.net needs to gather all the data info that was lost when you put the game on standby so when they try to shoot you .. you are not really there untill the server catches back up ... i have played with people who hit the switch ever 20 seconds .... fucked up lol



2nd the "Dummy Glitch"

1: you have to be an elite player not a human player (change this in settings)
2: you can not be the host of the party

-Have 2 guys get in a hog...
-Have someone jump in the drivers seat and gunner if you have the people and,
-Have the elite player sit on the passenger side. Have the elite press the X button and right before the elite fully gets out of the hog continuously press B, so it shows like your getting out but canceling at the last minute.
-The elite player will see himself sitting in the hog, but everyone else including his own teammates will see him jump out (but is in the seat).
-YOU NEED TO KEEP PRESSING THE B BUTTON this whole time, don't stop or you will jump out. you are invisible to everyone so you will have to let your driver know when you are back in the seat so he knows.
-Now drive off to the other base
-Stop the hog some were close to the flag.
-The driver or who ever will get the flag
at this time the elite will stop pressing the B button and he will jump out of the hog.
-DO NOT MOVE!! you can look around (up down, 360*, but don't walk) -So the elite is standing outside of the hog waiting for the guy who ran and grabbed the flag ...
-once you get the flag bring it to the passenger side of the hog where you "think" your friend the elite is and drop it ...
-the elite can then press the X button to pick up the flag ...
-once the elite has the flag MOVE FORWARD and you will respond back where your body is at your base and just go and capture

your body is invisible the whole time your playing ... but the "dummy" body that you left at your base can get killed (thus you die)
