How do I access someone's Halo3 fileshare if there not one of my recent players or friends?

Question

Do I have to add them as a friend or download it off the internet? Also I'm looking for the map Onslaught if any might have it.

Answer 1

Search their gamertag on Bungie.net and you'll be able to download whatever you want from their fileshare into yours.

Click download and then the next time you sign onto Xbox Live, it will show up in your downloads.

Or yeah, you could add them as a friend, but if you don't want them as your friend, it's much easier to just download it from the website.
