(adsbygoogle = window.adsbygoogle || []).push({}); if you already did the "one man spartan army" or w/e its called challenge, you can't do this.

Get to 399 kills (gruntocolypse is best way)

leave game

start new "score attack" matchmaking game, choose gruntocolypse, get one kill, when the challenge complete appears on screen pull the ethernet cord, then leave the game. than connect cord and sign back in, and do it again

if you have a slim it's too difficult and not worth it

I can see bungie banning for this.

yeah this is extremely banable and works with any challenge

If I do thisbjust 5 time will I get banned

i have a slim and i do this, except i use an ethernet cable
