Simply just go to the main menu sign in the 2nd profile and go to matchmaking, and if you tried that and it didn't work i don't know what to tell you. I tried it and it worked
Buy the game
matchmaking menu option.
Yes. Halo 3 and Halo: Reach both have Matchmaking.
yes but you can play matchmakeing firefight on your own
no... only if you want to play online matchmaking
You have to PLay Matchmaking for a long time it's one of the last ranks.
Yes, you can, but not in the campaign. Only in custom games, matchmaking, ect.
Campaign should be one of three options to choose from when you first play Halo Reach. It will show up along with Matchmaking and Theater on the main menu.
You get xbox live gold and then look for matchmaking in the main menu of the game.
The same way you would reach other ranks: play matchmaking, do daily challenges, and go for commendations
To play on Halo 3 matchmaking you must have a gold xbox live membership and an internet connection to play on matchmaking. If you only have a silver membership it will not let you play matchmaking.
the best in my opinion is Living Dead it is so fun
