Buy a flashed xbox, get iso download where you can use gpds online. Now plug disk into the console, say bunch of words, thats ok, then put gpd on profile, and plug back into xbox. load black ops, zombie patch, go to solo zombies make sure they work, then plug cat 5 cable in, and sign into xbox live, then exit solo zombies, go to zombies multiplayer, and find match, or host one yourself. For online 15th, plug gpd in profile, load black ops, go to multiplayer, then splitscreen, make sure mods work, sign into xbox live, then exit game, and go to multiplayer xbox live, private match host a match. Gratz

^^Before you do all this, have auto sign in off, and unplug ethernet cable.
