I wouldn't do that anyway because that sort of cheating just isn't me, but also it's traceable. The game tracks ALL your stats, this one guy on the Waypoint forums got caught out because Waypoint tracked him using multitudes of rockets. Dunno if it tracks hits taken but it'd track no deaths as each save and quit followed by resume game is logged as a new session.
Shame it didn't work, but I'm not risking my Xbox Live account over a freaking emblem, I've got plenty more.
I'm the squash for your juice, I'm pure, I'm concentrate.
Id also like to thank the little piece of tape i stuck in the middle of my TV screen that i used as my recticle for the last week (To compensate for the Blind skull). It served me well and will not be forgotten.
