Help with Legendary!

Hey guys, long story short I lost my old gamertag and now I am replaying through all the Halo games again :slight_smile:

Would anybody be interested in helping me on legendary for halo 3?

I also need reach, ODST and 4 but let’s start with 3!

Thanks guys!

Edit: My tag is ser0nex

I might be able to help. Whens the next time you would be on?
