i am positive what it is. first, YES it is a mod, it was on xbox live and they used a mod to put in the sliding and the person, second, it is also lag, either of these two they couldve used but on halogrid.com, the ghost himself says it was a mod. now speaking of mods, if nobody else has anything to say, then close this or somethin or just leave it alone is our best bet. now you know, "THE GHOST OF LOCKOUT"
