Personalized Campaign Xbox 360

(NOTE: THIS GLITCH IS FOR THOSE WHO DO NOT HAVE XBOX LIVE! ANY

      Ok, so I found this a few of years ago but didn't get to post it until now, anyway, 
what this glitch does is lets you play the campaign with what ever settings you want, 
(Health regen. , gravity, speed, weapon dmg. , etc. ) . To get it, follow the following 
instructions exactly:

 (*=required; (/)=optional)

1st - Go to the Main Menu >> System Link*

2nd - (X)CREATE >> (A)NEXT*

3rd - Change all of these setting anyway you want, and then, *

4th - Press: (X)SAVE >>[Name of it] >> (A)ACCEPT (/)

5th - (A)CREATE >> [And when it says "Couldn't start the Host", press (A)OK, & go 
all-he-way back to the main menu. ]*

     Once you get that done, start a campaign and when it loads and your playing, it'll 
have all of your settings on there! Have fun! (I like this one because as a person with 
no Gamertag for Xbox LIVE, I often find things that require it, and that ticks me off, 
so to all of the "non-LIVE'ers", this won't let you down, it'll only let the other with it 
down XD).
