you have to start a new xbox live account and create a new gamertag.
you have to restart the game and activate skulls from the main menu
i am VERY sorry to inform you of this, but you cant. in halo 3, halo reach, and halo 3: complete multiplayer experience you can.
Same exact experience of Halo 3.
You get the Halo 3 ODST campaign and Halo 3 multiplayer. Nothing else.
The way I did is you go to restart at last checkpoint or just restart the level
iron is a gold skull. when you activate it it will make your score higher. but if you die with it on, then you will restart from the last checkpoint.

play a ton of matches and win
SORRY BUT HALO IS A FAIR GAME THE ONLY ADVANTAGE YOU GET IS EXPERIENCE AND ADVANCED MOVES I KNOW THEM LOOK 4 ME (XxGWOPBOYZxX)
win, and go positive for that round... is that really how you earn xp ?
No u need 2 go online
Yes, but only on co-op there is no vs. mode, however the Halo 3 ODST case includes 2 discs one including Halo3 ODST and the other being the complete Halo 3 multi-player experience.
